High sensitivity HgCdTe focal plane arrays operating at 77 K can be tailored for response across the infrared spectrum. However, the cooling systems required to achieve the desired sensitivity makes them heavy and therefore unsuitable for the next generation of interceptor seekers. Reducing cooling requirements will allow the detector’s integration in lighter and more compact systems. Superior o ...

The objectives of this proposal are to develop and demonstrate a novel physics-based computational electromagnetics (CEM) algorithm for accurate and efficient predication of radar signatures of MDA objects of interest (MOIs) and to implement and demonstrate a robust stochastic collocation-based algorithm for efficiently quantifying the effect of geometrical and material uncertainties on the signat ...

Infrared photon sensors presently available for ballistic missile defense applications, with a cutoff wavelength ~10 micron, are based on HgCdTe. These suffer from a high non-uniformity and thus a high focal plane array cost. The most promising alternative is III-V compound semiconductor superlattices based on arsenides and antimonides, such as Type-II InAs/GaSb superlattices, which are expected ...

This small business innovation research Phase I proposal investigates a newly discovered high temperature amorphous oxide material (Cerablak) for use in a broad range of BMDO applications. Cerablak is thermally stable and remains amorphous up to 1400 C inoxidizing environments. No other oxide material is known to exhibit this metastable behavior. Cerablak is synthesized using a patented sol-gel ...

The main objective of the proposed Phase I project is to demonstrate a simple, scalable process to produce multiple, highly oriented, and longitudinally aligned 50-1000 nm wide YBCO filaments on Ni based tapes for efficient power generation application.The proposed process will take advantage of the well-known property that even a single monolayer of contamination is often sufficient to prevent ep ...

The availability of large format, multicolor, high performance infrared focal plane arrays is of the utmost importance to future DoD missions. The semiconductor HgCdTe is the material of choice for multicolor arrays due to its bandgap tunabilitythroughout the infrared spectral range and its high quantum efficiency. Present day 2nd generation focal plane array technology, based on the hybridizati ...

HgCdTe infrared arrays operating at 77K can now be tailored to a wide range of wavelengths ranging from 1 to 14 mm. However, the cooling requirements of traditional detectors make them bulky and unsuitable for many applications. Due to advancements inmaterials and device technologies, it is now possible to fabricate HgCdTe-based infrared arrays operating close to room temperature with sensitiviti ...

There is a growing trend towards the use of ¿Car-Less¿ technology, where a rail-car is not needed to transport road-haul trailers over rail: Trailers operate in the usual manner over highways, drive up to a rail yard and transform to ¿rail-mode¿ with relative ease. In rail mode, many ¿Car-Less¿ units use slightly modified 3-piece, 70-ton freight car trucks. These trucks are no ...
