We apply the theory of partially observable Markov decision processes (POMDPs) to the design of guidance algorithms for controlling the motion of unmanned aerial vehicles (UAVs) with on-board sensors for tracking multiple ground targets. While POMDPs are intractable to optimize exactly, principled approximation methods can be devised based on Bellman’s principle. We introduce a new approximation ...

Based on our success in developing the world first commercial high power femtosecond fiber laser system and our leading technology development in ultrashort pulsed fiber laser and nonlinear fiber optics, PolarOnyx proposes, for the first time, a compact all fiber based high power (>kW) mid-IR supercontinuum source (1-5 micron) to meet with the requirement of the AF solicitation AF09-BT01. The lase ...

Recent advances in dielectric and magnetic materials have spurred renewed interest in the field of solid state pulse and RF burst generation using Non-Linear Transmission Lines (NLTL) . The NLTL approach to HPM and UWB generation eliminates the need for an electron beam, vacuum system and magnets required in conventional HPM sources. Furthermore, the novel waveforms of NLTL generated pulses promi ...

Existing computer combat wargames offer a sophisticated and high fidelity base platform for accurately modeling standard combat scenarios. However, the rapid development of UAV capabilities in terms of sizes, weapons, sensors, communications and flight ability is presenting a new challenge for these simulations. At the same time, the general state of world affairs is changing such that the likeli ...

Higher efficiency solar cells are needed to reduce solar array mass, volume, and cost for Air Force space missions. Intermediate-band quantum-dot (QD) solar cells can yield dramatically higher efficiencies than current multi-junction (MJ) technologies. However, several issues must be addressed to demonstrate manufacturable, high efficiency devices. CFDRC aims to develop: 1) High-efficiency, ligh ...

The United States Missile Defense Agency (MDA) is searching for a software-defined multi-channel radar receiver that would provide improved performance and added flexibility over currently deployed radar systems. In response, MaXentric is proposing a system codenamed MASR (Manycore Adaptive Software Radar). The MASR system is composed of a hierarchy of X-band front-ends, high-speed digitizers, F ...

Higher efficiency solar cells are needed to reduce mass, volume, and cost of DoD space missions. However, to achieve higher efficiency and radiation hardness of the best to date multi-junction photovoltaic (PV) devices, several challenges must be addressed. This project aims to develop: 1) Quantum Well (QW)-based multi-junction cell that exhibits enhanced efficiency, and 2) Radiation-hardened PV c ...

Compelling applications of infrared ultrafast lasers—ranging from ship self defense and aircraft self defense, to medical and micromachining applications—have defined a critical performance point at about one millijoule per pulse from a reliable and robust portable laser system with high average power. Increasing amplifier efficiency is a critical need in order to reach high average powers nee ...

Recent advances in THz-source stability, power and practicality have opened the door for active THz imaging in both commercial and military settings. AEgis is teaming with U Buffalo to develop a THz detection device that utilizes classical rectification effects in semiconductor point contacts (SPCs) to achieve response in the 1 to 10 THz range and is capable of operating at temperatures over 150 K ...

We propose algorithm development and efficient GPU implementation of numerical PDE solvers based on four novel high-order methodologies: 1) High-order Discontinuous Galerkin approaches, 2) Fast High-Order boundary integral methods, 3) Convergent FFT-based methodologies for evaluation of computational boundary conditions, and 4) Fourier Continuation methods. These methodologies are applicable to a ...
