ABSTRACT: Sapphire possesses a number of physical properties, including high strength, high melting point, chemical inertness, and excellent transparency in the visible and IR spectrum, which make it an attractive window material for military applications. For Phase I, Rubicon Technology demonstrated a sapphire crystal growth process to MRL 5 capable of growing slabs 20"x 14". During Phase II th ...

ABSTRACT: Voxtel"s proposes the development of a High Energy Event Tracking (HEET) readout integrated circuit (ROIC), optimized for the identification and tracking of high energy events within a large format staring infrared sensor. Working with the AFRL program office, in Phase I, Voxtel has developed a novel ROIC architecture that simultaneously provides the system with standard video imaging d ...

Many hardware trojans depend on (a) the ability of an attacker to have an accurate model of the target system and of key software used on that system and (b) identification of one or more deterministic trigger conditions with low observability (i.e., conditions that evade detection by traditional scan- or ATPG-based testing methodologies but that can be exercised on demand via external stimuli). ...

ABSTRACT: MicroLink will develop a high-efficiency, flexible photovoltaic blanket, which will reduce solider borne weight by reducing battery requirements. The photovoltaic blanket will combine ultra-thin, flexible high-efficiency, GaAs-based multi-junction solar cells, made using MicroLink"s proprietary epitaxial lift-off (ELO) process, with a novel packaging approach that involves laminating a ...

The use of synthetic data for the generation of target signature templates is a vital element of current and future automatic target recognition systems. [1] [2] Although current synthetic signatures closely match their measured counterparts, they suffer from two shortcomings: 1) susceptibility to model error and 2) poor representation of signature variance. The current model validation relie ...

ABSTRACT: Quantum key distribution (QKD) is an exciting application of quantum theory to the important real-world problem of secure communication. Specifically, QKD may allow for provably secure key distribution. These random keys can then be used either in a one-time pad style encryption system (for absolute security at low rates) or a standard encryption system (for high security at high rates) ...

ABSTRACT: Tezzaron proposes to develop and demonstrate a 64Mb 3D integrated MRAM device comprising one non-volatile memory cell layer and one radiation hardened I/O logic and control layer. This memory device will address the industry"s next generation needs for nonvolatile memory density and also, because of its virtually unlimited wearout lifetime, act as next main memory, reducing overall comp ...

The fabrication of large format, long wavelength (LWIR) mercury cadmium telluride based focal plane arrays (FPAs) is highly desirable for Air Force applications such as satellite power and array cooling reduction along with higher resolution. However, the development of large FPAs has been seriously impeded by the limited size of commercially available bulk Cd{sub 1-x}Zn{sub x}Te substrates. In ...

Techical advances in two dimensional staring focal plan arrays (FPSs) have stimulated research to utilize FPSs in spectrometer instrumentation with the goal of increased spectral, spatial and temporal resolution. Conventional staring FPA spectrometers create a three dimensional image (two spatial and one spectral) by either using a sequence of narrow band spectral filters to slice the ...

Large planar arrays which consist of several hundred to several thousand antennas provide narrow, high gain pencil beams. Electronic beam steering for terminal guidance radar can be achiev ed using frequency scanning, beam switching, time delay or phase delay. Electronics steering allows beam manipulations in tens of nanoseconds using compact, mechanically rigid structures. Due to the increase in ...
