ABSTRACT: Over the past decade, there has been a sustained interest in Global Positioning System (GPS) denied navigation technologies for unmanned aircraft systems (UAS). This has been primarily due to the well accepted susceptibility of GPS signals to intentional jamming or unintentional interference and blockage. One of the challenging problems in GPS-denied navigation is handing off moving targ ...

ABSTRACT: Toyon Research Corp. and the Penn State Univ. propose research and development of innovative algorithms for classifying objects and activities observed in high-dimensional data, including video and hyperspectral imagery. The proposed algorithms include novel feature clustering techniques to enable effective characterization of intra-class and inter-class appearance variations in datasets ...

ABSTRACT: Analysis and Applications and Associates, Inc. (AAA) proposes to develop software that evaluates effects of the hypersonic flow environment on electro-optic/infrared optical systems and vehicles for specific hypersonic flight profiles. We propose a high fidelity definition of the near-field flow, using the latest CFD and turbulence modeling technologies, to determine the environment from ...

ABSTRACT: MZA partnered with the University of Notre Dame proposes to extend MZAs WaveTrain wave-optics sensor simulation framework to model EO/IR sensors operating on hypersonic aircraft. Following the methods we have developed for aero-optical imaging through subsonic, transonic, and supersonic flows, existing WaveTrain libraries will be expanded to include hypersonic flow, shocks, thermal effec ...

ABSTRACT: This project will develop and demonstrate a software package based on coupled Fokker-Planck (FP) - Fermi Kinetic Transport (FKT) models and full-wave Maxwell electromagnetic (EM) solver to accurately predict semiconductor device behavior from dc up through the mm-wave and THz frequency ranges. The FP model provides accurate non-equilibrium occupation functions for hot electrons with real ...

ABSTRACT: The next-generation Global Positioning System (GPS) in congested and contested environments is expected to exploit Spectrum Holes (SH) in order to provide uninterrupted Position Navigation and Timing (PNT) service worldwide. Innoflight has teamed with the Air Force Institute of Technologys (AFITs) Autonomy and Navigation Technology (ANT) Center to develop a system based on cognitive radi ...

ABSTRACT: The effects of fatigue and exhaustion can have significant effects on the capabilities of personnel throughout the military and civilian sectors. Current methods to evaluate and reduce the effects of severe fatigue and exhaustion include self-reporting, assessment using simple cognitive tests and exercises, and the implementation of fatigue management programs. Detection of chemical ind ...

ABSTRACT: To address the Air Force need for a nondestructive evaluation technique applicable to energetic composites with low density gradients, Luminit, LLC, and Southern Illinois University Intelligent Measurement and Evaluation Laboratory propose to develop a new Compression Imaging Phase Array Ultrasound Interrogator (CIPHOR) system based on phased array higher frequency ultrasonic imaging. ...

ABSTRACT: In this effort, Freedom Photonics will develop a high-sensitivity high-resolution coherent imaging system based on a Si avalanche photodiode (APD) array and corresponding bias and read-out electronics. This will be a monolithic APD and ROIC (readout-integrated-circuit) focal plane array (FPA) system. We start from a proven high-performance CMOS electronics backplane and build the photon ...

ABSTRACT: The United States relies heavily on force multiplying, space-based navigation, communications and intelligence, surveillance and reconnaissance (ISR) capabilities. These satellites populate all orbital regimes including low-earth orbit (LEO), medium earth orbit (MEO) and geosynchronous earth orbit (GEO) and frequently require complex ground station network support requirements. Miltary ...
