Exploring Potential ADS-B Vulnerabilities in the FAA's NextGen Air Transportation System
The Federal Aviation Administration's (FAA) Next Generation upgrade proposes a fundamental transformation to thenational airspace system (NAS) that aims to reduce dependence on outdated radar infrastructure, increase airline safetyand condense required aircraft spatial separation. A key component of the upgrade is the Automatic DependentSurveillance-Broadcast (ADS-B) system. ADS-B provides continual broadcast of aircraft position, identity, velocityand other information over unencrypted data links to generate a precise air picture for air traffic management. Officialdocuments claim operational requirements necessitate unencrypted data links while maintaining that there is a lowlikelihood for malicious exploitation. This paper studies the security vulnerabilities associated with the ADS-Bimplementation plan and develops a taxonomy to classify attacks and examine potential impacts the attacks have onoverall NAS operations. The taxonomy helps provide a comprehensive understanding of the threats associated withADS-B implementation and facilitates risk analysis and risk management.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Pulse Shaped 8-PSK Bandwidth Efficiency and Spectral Spike Elimination
The most bandwidth-efficient communication methods are imperative to cope with the congested frequency bands. Pulse shaping methods have excellent effects on narrowing bandwidth and increasing band utilization. The position of the baseband filters for the pulse shaping is crucial. Post-modulation pulse shaping (a low pass filter is located after the modulator) can change signals from constant envelope to non-constant envelope, and non-constant envelope signals through non-linear device (a SSPA or TWT) can further spread the power spectra. Pre-modulation pulse shaping (a filter is located before the modulator) will have constant envelope. These two pulse shaping methods have different effects on narrowing the bandwidth and producing bit errors. This report studied the effect of various pre-modulation pulse shaping filters with respect to bandwidth, spectral spikes and bit error rate. A pre-modulation pulse shaped 8-ary Phase Shift Keying (8PSK) modulation was used throughout the simulations. In addition to traditional pulse shaping filters, such as Bessel, Butterworth and Square Root Raised Cosine (SRRC), other kinds of filters or pulse waveforms were also studied in the pre-modulation pulse shaping method. Simulations were conducted by using the Signal Processing Worksystem (SPW) software package on HP workstations which simulated the power spectral density of pulse shaped 8-PSK signals, end to end system performance and bit error rates (BERS) as a function of Eb/No using pulse shaping in an AWGN channel. These results are compared with the post-modulation pulse shaped 8-PSK results. The simulations indicate traditional pulse shaping filters used in pre-modulation pulse shaping may produce narrower bandwidth, but with worse BER than those in post-modulation pulse shaping. Theory and simulations show pre- modulation pulse shaping could also produce discrete line power spectra (spikes) at regular frequency intervals.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Impact of Snow Removal Operations on Thermoplastic Pavement Markings
This pilot study explored the effect snow removal operations have on thermoplastic pavement markings. Including snow removal as a separate independent variable is unique because much of the previous research performed on pavement marking degradation mentioned snow removal as a direct cause in a marking degrading more rapidly; however, it is mentioned as an afterthought and a suggestion to be considered in future research. This pilot study looked at 10 thermoplastic markings and all marking data were collected in the field, using a hand-held retroreflectometer. Data collected began 60 days after initial marking application and ended 12 months after initial marking application. Data were analyzed using linear regression. A significant finding was that during the first year, white thermoplastic markings located in the center of the road, and that are exposed to snow removal operations do not reach the apex of their break-in phase. Thus the start of the linear degradation phase does not start until at least one year after initial application.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Radar Orbit Analysis Tool Using Least Squares Estimator
Most objects tracked in space follow a regular Keplerian orbit; unfortunately, non-Keplerian objects such as maneuvering satellites, tethered systems, and thrusting ballistic missiles are becoming more common. It is important to be able to distinguish between Keplerian and non-Keplerian objects due to the potential risk of a tethered satellite being mistaken for an object on re-entry. This research focused on creating a computer model that can detect the non-gravitational acceleration present in non- Keplerian orbits. A 3rd order Taylor series expansion was used to model the dynamics and to produce simulated radar data. Linear least squares estimation was used to estimate the initial state of a space object with a state vector composed of position, velocity, acceleration, and its first derivative. Monte Carlo analysis was used to verify that the estimator was unbiased and representative of the uncertainty in the data. The Monte Carlo method detected non-gravitational acceleration as small as 1.12 cm/s2; however, a subsequent approach that analyzed the data sets individually only detected acceleration as small as 10.63 cm/s2. At smaller magnitudes, the estimator was able to detect the presence of non-gravitational acceleration, but was ultimately unable to estimate the true value with statistical accuracy.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

An Estimation Theory Approach to Detection and Ranging of Obscured Targets in 3-D LADAR Data
The purpose of this research is to develop an algorithm to detect obscured images in 3-D LADAR data. The real data used for this research was gathered using a FLASH LADAR system under development at AFRL/SNJM. The system transmits light with a wavelength of 1.55 micrometers and produces 20 128 X 128 temporally resolved images from the return pulse separated by less than 2 nanoseconds in time. New algorithms for estimating the range to a target in 3-D FLASH LADAR data were developed. Results from processing real data are presented and compared to the traditional correlation receiver for extracting ranges to the target. This research shows that the algorithms presented are capable of distinguishing two surfaces separated by only 40 inches using real data.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Assessment of the Undiscovered oil and gas of the Senegal Province, Mauritania, Senegal, the Gambia, and Guinea-Bissau, Northwest Africa
Undiscovered, conventional oil and gas resources were assessed in the Senegal Province as part of the U.S. Geological Survey World Petroleum Assessment 2000 (U.S. Geological Survey World Energy Assessment Team, 2000). Although several total petroleum systems may exist in the province, only one composite total petroleum system, the Cretaceous-Tertiary Composite Total Petroleum System, was defined with one assessment unit, the Coastal Plain and Offshore Assessment Unit, having sufficient data to allow quantitative assessment. The primary source rocks for the Cretaceous-Tertiary Composite Total Petroleum System are the Cenomanian-Turonian marine shales. The Turonian shales can be as much as 150 meters thick and contain Type II organic carbon ranging from 3 to 10 weight percent. In the Senegal Province, source rocks are mature even when situated at depths relatively shallow for continental passive margin basins. Reservoir rocks consist of Upper Cretaceous sandstones and lower Tertiary clastic and carbonate rocks. The Lower Cretaceous platform carbonate rocks (sealed by Cenomanian shales) have porosities ranging from 10 to 23 percent. Oligocene carbonate rock reservoirs exist, such as the Dome Flore field, which contains as much as 1 billion barrels of heavy oil (10? API, 1.6 percent sulfur) in place. The traps are a combination of structural closures and stratigraphic pinch-outs. Hydrocarbon production in the Senegal Province to date has been limited to several small oil and gas fields around Cape Verde (also known as the Dakar Peninsula) from Upper Cretaceous sandstone reservoirs bounded by normal faults, of which three fields (two gas and one oil) exceed the minimum size assessed in this study (1 MMBO; 6 BCFG). Discovered known oil resources in the Senegal Province are 10 MMBO, with known gas resources of 49 BCFG (Petroconsultants, 1996). This study estimates that 10 percent of the total number of potential oil and gas fields (both discovered and undiscovered) of at least the minimum size have been discovered. The estimated mean size and number of assessed, undiscovered oil fields are 13 MMBO and 13 fields, respectively, whereas the mean size and number of undiscovered gas fields are estimated to be 50 BCFG and 11 fields. The mean estimates for undiscovered conventional petroleum resources are 157 MMBO, 856 BCFG, and 43 MMBNGL (table 2). The mean sizes of the largest anticipated undiscovered oil and gas fields are 66 MMBO and 208 BCFG, respectively. The Senegal Province is underexplored considering its large size. The province has hydrocarbon potential in both the offshore and onshore, and undiscovered gas resources may be significant and accessible in areas where the zone of oil generation is relatively shallow.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Energy
This paper examines the state of the nation and the Air Force with regard to energy. First, it describes in detail the "perfect storm," or convergence of reasons why the problem of energy dependence deserves immediate and uncompromising attention. In short, there exists a three-pronged threat of environmental damage, market instability associated with crude oil depletion, and most importantly, energy security issues that must be addressed. The paper argues that energy independence is the answer. The US Air Force, as the single largest institutional consumer of oil in the United States, is in a position similar to that of the nation as a whole who, despite representing only about 5 percent of the world's population, consumes 25 percent of the world's oil. Both the United States and the Air Force are thus in positions of responsibility and poised to serve as an example for others. The second portion of the paper describes initiatives either already undertaken or planned by the Air Force to help in becoming more energy independent.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Impact of Snow Removal Operations on Thermoplastic Pavement Markings
This pilot study explored the effect snow removal operations have on thermoplastic pavement markings. Including snow removal as a separate independent variable is unique because much of the previous research performed on pavement marking degradation mentioned snow removal as a direct cause in a marking degrading more rapidly; however, it is mentioned as an afterthought and a suggestion to be considered in future research. This pilot study looked at 10 thermoplastic markings and all marking data were collected in the field, using a hand-held retroreflectometer. Data collected began 60 days after initial marking application and ended 12 months after initial marking application. Data were analyzed using linear regression. A significant finding was that during the first year, white thermoplastic markings located in the center of the road, and that are exposed to snow removal operations do not reach the apex of their break-in phase. Thus the start of the linear degradation phase does not start until at least one year after initial application.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Development of an Experimental Platform for Testing Autonomous UAV Guidance and Control Algorithms
With the United States' push towards using unmanned aerial vehicles (UAVs) for more military missions, wide area search theory is being researched to determine the viability of multiple vehicle autonomous searches over the battle area. Previous work includes theoretical development of detection and attack probabilities while taking into account known enemy presence within the search environment. Simulations have been able to transform these theories into code to predict the UAV performance against known numbers of true and false targets. The next step to transitioning these autonomous search algorithms to an operational environment is the experimental testing of these theories through the use of surrogate vehicles, to determine if the guidance and control laws developed can guide the vehicles when operating in search areas with true and false targets. In addition to the challenge of experimental implementation, dynamic scaling must also be considered so that these smaller surrogate vehicles will scale to full size UAVs performing searches in real world scenarios. This research demonstrates the ability of a given sensor to use a basic ATR algorithm to identify targets in a search area based on its size and color. With this ability, the system's target thresholds can also be altered to mimic real world UAV sensor performance. It also builds on previous dynamic scaling studies to show that the performance of a full size UAV can be imitated using a surrogate vehicle. Further investigation will show sensor orientation, field of view, vehicle geometry, and the known size of the target can be used to determine target pixel thresholds as well as the vehicle steering correction angle to navigate directly over the centroid of an identified target.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Wide-Angle Multistatic Synthetic Aperture Radar
Traditional monostatic Synthetic Aperture Radar (SAR) platforms force the user to choose between two image types: larger, low resolution images or smaller, high resolution images. Switching to a Wide-Angle Multistatic Synthetic Aperture Radar (WAM-SAR) approach allows formation of large high-resolution images. Unfortunately, WAM-SAR suffers from two significant implementation problems. First, wavefront curvature effects, non-linear flight paths, and warped ground planes lead to image defocusing with traditional SAR processing methods. A new 3-D monostatic/bistatic image formation routine solves the defocusing problem, correcting for all relevant wide-angle effects. Inverse SAR (ISAR) imagery from a Radar Cross Section (RCS) chamber validates this approach. The second implementation problem stems from the large Doppler spread in the wide-angle scene, leading to severe aliasing problems. This research effort develops a new anti-aliasing technique using randomized Stepped-Frequency (SF) waveforms to form Doppler filter nulls coinciding with aliasing artifact locations. Both simulation and laboratory results demonstrate effective performance, eliminating more than 99% of the aliased energy.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Vibration Analysis of Commercial Thermal Barrier Coatings
Thermal barrier coatings (TBCs) are currently used in turbine engine components to protect substrate material from exposure to high temperature and corrosion. These coatings have the potential to reduce stress in critical engine parts which could increase the life cycle of these parts. The fact that these coatings are already qualified for use in turbine engines makes it worth investigating their damping properties. The problem with TBCs is that they are difficult to characterize as they display nonlinear properties. This research utilizes an experimental and finite element procedure to characterize these coatings. A scanning electron microscope (SEM) was employed to observe the microstructure contribution to the damping properties.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Design and Validation of an Sccurate GPS Signal and Receiver Truth Model for Comparing Advanced Receiver Processing Techniques
Recent increases in the computational power of computers and digital signal processors have made possible new, novel signal tracking techniques in GPS receivers. One such technique is known as Direct Correlator Output Processing (DCOP). This technique replaces individual traditional tracking loops with a single Kalman Filter, which jointly processes the received signals while exploiting their correlated noises. DCOP is innovative in its potential to replace the tried and true classical signal tracking loops. It is also an enabling technology for ultra-tightly coupled GPS/INS (Global Positioning System/Inertial Navigation System). Potential benefits of these new tracking techniques include an order-of-magnitude improvement in positional accuracy in environments of jamming and high dynamics. However, such performance gains are typically based on software simulations of conceptual GPS receiver designs, not working prototypes. Simulating these new designs requires the modeling of GPS signals and receiver tracking loops, instead of the traditional pseudorange and carrier-phase measurements, which many proven GPS simulation software packages accurately model.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Hybrid Micro-Electro-Mechanical Tunable Filter
While advantages such as good thermal stability and processing-chemical compatibilities exist for common monolithic-integrated micro-electro-mechanically tunable filters (MEM-TF) and MEM-tunable vertical cavity surface emitting lasers (MT-VCSEL), they often require full processingto determine device characteristics. Alternatively, the MEM actuators and the optical parts maybe fabricated separately, then subsequently bonded. This "hybrid approach" potentially increases design flexibility. Since hybrid techniques allow integration of heterogeneous material systems, "best of breed" compound optoelectronic devices may be customized to enable materials groups to be optimized for tasksthey arebest suited.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
