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 ...

We propose a new fiber WDM fabrication method for single mode high power fiber laser. Our new approach will enable kW operation for both single mode fiber WDM and PCF WDM. In Phase I, a proof of concept experiment has been demonstrated. In phase II, we will target at delivery of a reliable prototypes for both step index fiber WDM and PCF WDM.

ABSTRACT: Hypersonic vehicles will require structures that can withstand highly transient flows and complex loadings throughout the flight trajectory. Shock boundary-layer interaction can excite panels locally and lead to structural failures. Non-contacting measurement technologies are needed to characterize the effect of flow transients (due to pressure and temperature fluctuations) on the struct ...

ABSTRACT: Exquadrum, Inc. proposes to develop an innovative multi-mode power generation system for hypersonic flight vehicles. This system produces the required power output that the flight vehicle demands, independent of the flight characteristics at the time. However, this system will work in conjunction with the propulsion system to augment the power generation capabilities. This is accomplishe ...

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 ...

Experimental data from a number of DoD supported research programs have indicated that electrical systems capable of producing highly repetitive bursts of high voltage, fast risetime pulses are a critical enabling technology for applications tied to nonequilibrium physical processes, such as combustion, boundary layer flow, and the generation of high power EM waves. Recognizing the important role ...

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: We propose here a robust production-level high-order mesh generation software for complex geometries. High order accurate numerical methods are becoming increasingly popular in the present time and have demonstrated a great measure of success in efficient error-controlled simulations for a wide variety of important problems. A curved geometry and mesh generation system is essential in m ...

ABSTRACT: XL Scientific LLC will leverage over a half a century of High Power Microwave (HPM) Effects Test and Modeling experience to develop an integrated DREAM2 toolkit that models the vulnerability and susceptibility of electronic systems, subsystems and components to directed energy (DE) HPM weapons. The analysis toolkit developed will center on three essential modules, critical in a full asse ...
