In order to provide the required simulation frame rates we propose to decouple the incident flux calculations from a simple thermal response model. We propose to develop a table-lookup methodology based on high fidelity precomputed environmental and eventually aerothermal fluxes which can be draw in real time to drive the thermal response model. A simple 1-D thermal calculation based on an analyt ...

Current state-of-the-art infrared focal plane arrays are based on HgCdTe grown on bulk CdZnTe substrates. The use of Si-based substrates would eliminate a number of drawbacks related to the HgCdTe/CdZnTe system and permit larger formats. We have developed growth protocols that produce material with good crystal quality for such a highly mismatched heteroepitaxial system. Double crystal rocking c ...

Hydrogen isotopes have been shown to reduce the electrical effects of various semiconductor defects. Specifically, monoatomic hydrogen and deuterium passivate the electrical activity of defects such as dislocations in long-wavelength HgCdTe grown on Si. We propose a novel method of controlling the intake of hydrogen in HgCdTe IRFPAs by using the H2/He plasma afterglow formed by flowing plasma-gene ...

Current state-of-the-art infrared focal plane arrays (IRFPAs) are based on HgCdTe material epitaxially grown on bulk CdZnTe substrates. The size of the IRFPAs is limited by the size of the available CdZnTe substrates and the thermal mismatch between CdZnTe and the Si readout circuit, which misaligns the photodiode array with respect to the circuit during heating and cooling cycles. Having HgCdTe ...

An innovative, super-miniature, fast-switching array-based photonic time delay device is being developed for the active electronically scanned-array (AESA) MDA and Navy radars. The design is based on the fast electro-optic effect, the super miniature fiber-lens collimation array, and the existing WDM photonic true time delay technologies. In Phase I Agiltron has successfully demonstrated the core ...

Physical Sciences Inc. (PSI) proposes to develop, evaluate, and test new elements of a sensor fusion architecture for Command, Control, and Battle Management and Communications (C2BMC) for Ballistic Missile Defense (BMD). PSI proposes an innovative architecture designed to leverage sensor diversity and multimodal feature extraction to provide Enhanced C2BMC functionality in search, track, discrimi ...

Fusing data together for target tracking is a complex problem. There are two elements: First, the raw observations must be associated with existing tracks or used to form new tracks. Once the association has been done, then the tracks can be updated and filtered with the new data. When associating data (either measurements or tracks or both) with existing tracks, the separation between the trac ...

Missile defense takes place in a dynamic, uncertain environment. Multi-raid attacks threaten to overload sensor capabilities, leaving fewer sensor resources free to observe each target complex. Moreover, the shift in emphasis toward early intercept, coupled with the growing importance of short- and medium-range threats, reduces the time available for detection, tracking, and discrimination, becaus ...

Detecting, localizing, identifying, tracking, and intercepting multiple and dispersed missiles aimed at multiple and dispersed defended areas, presents a daunting theoretical and practical challenge. The Scientific Systems Company, Inc. team proposes a foundational, information-theoretic and controltheoretic approach. It is based on mathematically modeling a multiplatform-multisensor-multitarget s ...

Knowledge Based Systems, Inc. (KBSI) proposes to investigate innovative methodologies and algorithms for Efficient Sensor Management for Optimal Multi-Task Performance (ES-MaTe), The goal of the proposed research is to investigate an efficient sensor resource management method for sensor scheduling specific to tasks required by a missile defense system. The Ballistic Missile Defense System uses ...
