On the remote tracking station (RTS) side, switched beam smart antenna, distributed beam forming technique, multiple access technique based on FDMA and/or CDMA are applied to obtain multiple satellites reception objective. On the satellite si ...

ABSTRACT: In this proposal a Game-theoretic Universal Anti-RFI Defense (GUARD) framework for Satellite Communications is proposed. Key components of the GUARD framework include i) Radio Frequency Interferences (RFI) modeling and impact evaluation infrastructure, which allows the evaluation of the impact of RFI from various sources, and provides a comprehensive RFI knowledge base to SATCOM; ii) RF ...

ABSTRACT: Our main objective in this project is to propose a novel Structured Sparse Priors for Target Recognition (SSPTR) system and to demonstrate that discriminative applications such as data clustering or target detection, tracking, and classification can be solved effectively and directly on the compressed measurement domain without the need to recover the original data. Our proposed sparse-r ...

ABSTRACT: A range segment upgrade for Air Force satellite control network (AFSCN) will significantly improve system effectiveness via spectrum sharing and seamless interoperation. However, the upgraded system requires new capabilities such as real-time and accurate RF interference detection and mitigation, array antenna backlobe/sidelobe suppressions, accurate performance degradation prediction, ...

ABSTRACT: Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal cracking of hydrocarbon fuels is always accompanied by coke formation. The coke deposits on the combustor and nozzle walls reduces heat fluxes and c ...

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: This Phase I effort will involve the development of an ultra low cost, high specific power, modular and flexible solar array module using currently available thin-film solar cells, innovative interconnects, and flexible encapsulation. The high efficiency thin-film solar cells will enable high specific power and flexibility in the module. The interconnect scheme and encapsulation will a ...

ABSTRACT: The ability of plasmas to modify combustion has been known for more than 50 years. Recent advances in plasma generation technology and measurement diagnostics have led to extensive efforts to understand both the kinetics of the plasma-flame interaction and the enhancement of combustion properties such as ignition, extinction, flame speed and dynamics. Combustion Science & Engineering, ...

ABSTRACT: Ramjets and scramjets are the preferred propulsion platforms for flight in the supersonic (3

ABSTRACT: This Small Business Technology Transfer Phase I project develops collaborative spectrum awareness techniques that enable dynamic spectrum access (DSA) systems to make decisions with imperfect awareness. DSA technologies are emerging as a promising mitigator against spectrum congestion resulting from the explosive growth in commercial and Government wireless systems and services. DSA sys ...
