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 ...

The first sentinel of ABL’s present target acquisition suite is a passive infrared search and track sensor of 1970s vintage, which we propose replacing with HyPAWS. HyPAWS is a low-cost passive wide-field of view staring sensor. Several such units suffice to provide full 360-degree view coverage. Leveraging revolutionary sensing techniques in ongoing development, HyPAWS offers advanced detect ...

It is proposed to investigate an innovative mitigation technique for insensitive munitions through a new rocket motor case design. The proposed study will focus upon developing a motor case with sympathetic responses to unplanned thermal stimuli. This particular motor case design will be according to current operating mission parameters for a specific MDA rocket booster.

The insider threat remains one of the most difficult to detect -- left alone to mitigate -- threats against information systems. The overall objective of the effort (Phase I and Phase II) is to produce and prototype a Distributed Insider Threat Detection System (DITDS) for distributed environments, capable of identifying and quantifying emerging insider threats against the network, allowing for t ...

The objective of this program is to characterize the upper atmosphere electrical environment so that the effects of this environment on high altitude airships (HAA) and other platforms intending to operate in this environment can be determined, and protection methods developed. This includes transient luminous events (TLEs), such as red sprites and blue jets and their associated electrical propert ...

Radiation Hardened Multi-color infrared (IR) focal planes are required for MDA/SMDC systems applications . Key to meeting these system requirements is to develop multi-color radiation hardened HgCdTe focal plane arrays for LWIR band ( 7-14 microns) and VLWIR band with wavelength of greater than 14 microns with high pixel uniformity, reduced readout noise, improved resolution, and higher temperatur ...

Highly energetic chemical processes play a central role in many military and commercial applications. For example, spectral emissions from missile plumes, arising from high-velocity chemical interactions of exhaust gases with the atmosphere, are used to detect, track, and identify threat targets. Detailed, quantitative knowledge of the energy-dependent chemical reaction cross sections and rates i ...

Silicon has long been the semiconductor of choice for high-voltage power electronic applications. Recently, SiC has attracted attention because SiC is projected to have better performance than silicon. [1] SiC power switching devices have yet to becommercialized, largely due to SiC crystal defects, most notably the device-killing micropipe defect, which does not permit high total current parts t ...

A random access, solid-state, optical cross-switch capable of 770 channel discrimination in the telecommunications C-band is designed and proven as an alternative to current thin-film WDM devices and as a mechanically robust alternative tomicroelectromechanical (MEMS) WDM devices. The device may be used in multiplexing (mux), demultiplexing (demux), or complete cross-switch configurations, and is ...

The wide-bandgap semiconductors GaN and SiC hold great promise for high temperature and highpower electronic devices. This is due to the attractive properties these materials possess, such as wide energy bandgaps, high breakdown fields, high thermalconductivities, and high saturated electron velocities. In addition, GaN and SiC have adequate electron mobilities and can readily be doped n and p ty ...
