The goal of this program is to develop and implement optimal spectral signature detection techniques which provide automated detection and identification of materials in hyperspectral image sequences. The requirement to detect, identify and discriminate materials is a common theme in many… More

Not Available We propose to develop a high speed tunable semiconductor laser source for tue time delay beam steering of phased array radar antenna systems. The source will be based on a widely tunable multi-section integrated semiconductor laser with all electronic tuning. We will develop a control… More

With the advent of high quality hyperspectral sensors there has been parallel research and substantial improvement in the signal processing and exploitation of the spectral data sets. Several recent hyperspectral collection campaigns conducted by the ArmyNight Vision Laboratory and the Central… More

Precise geolocation of deployed sonobuoys is a standing requirement of the U.S. Navy for improving ASW operations. Current approaches to sonobuoy localization often require close over-flight of the sonobuoy by the monitoring aircraft. This compromisesthe security of the aircraft, and does not… More

The SOCOM direction finding (DF) requirement is a small, low-power package that is modular in design and capable of interoperating with a variety of receivers including the SIGINT Threat Warning receivers currently under development by Digital ReceiverTechnology, Inc. and Applied Signal Technology,… More

To maximize the utility of spectral imagery sensors it is essential that processing techniques for data from these sensors are highly automated, provide high probability of target detection with low false alarm rates, and offer a reliable confidence assessment capability. The detection and false… More

The availability of low cost global positioning system (GPS) jammer systems provides the potential for an adversary to severely limit the utility of one of the United States' most important navigation and timing resources. During the recent conflict in Iraq, GPS jammer systems developed by the… More
