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 ...

Overhead imagery analysts employ computer-based software as Electronic Light Tables (ELTs), to perform detailed analysis of aerial images in search of elements of interest. Conventional display design for ELT software requires analysts to take their eyes away from the image they are analyzing to perform routine functions. This interaction overhead typically leads to losses in visual momentum and i ...

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 ...

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 ...

This effort will demonstrate a scalable aerial platform architecture which matches the scalability necessary for expandable missile defense communications architectures directly supporting all Missile Defense Agency (MDA) missions.

High efficiency heat-sinks for thermal management of high energy solid state lasers are proposed. Advanced heat sink technology enables increased performance of directed energy solid state lasers. Efficient high performance thermal management materials representing next generation thermal expansion matched high thermal conductivity heat sinks are proposed with an additional level of hybridizatio ...
