Future battlefields will require independent operations and increased operational tempo, placing severe burdens on weapons platform crewmembers in the areas of information flow management, data fusion, and assessment of data to arrive at the most tactically acceptable decisions. Work continues in the development of decision aids to assist direct/indirect fire weapon platform commanders in accompl ...

The field training of Reserve Component units is difficult because of limited training time and facilities and the difficulty in assembling all necessary player personnel. Computer wargames which allow interactive play of player personnel are a relatively inexpensive alternative and supplement to field exercises. Unfortunately, most existing simulations are designed to exercise maneuver command an ...

APA Optics will develop a monolithic UV seeker for use in flame sensing and passive or tactical threat warning systems. The key to the technical approach is the deposition of high optical/electrical quality Al(x)Ga(1-x)N over GaAs substrates and using it to fabricate back to back Schottky barrier detectors. Al(x)Ga(1-x)N is a compound III/V semiconductor system with a bandgap tunable from 220 to 3 ...

We propose a six month Phase I program to demonstrate the feasibility of growing A1N single crystals to serve as substrates for subsequent A1xGa1xN epitaxy. Our approach is to use a low pressure, high temperature (>>2000oC) furnace with a temperature gradient between the A1N charge and the deposition (seed) regions. Our approach is based on several innovations. These include the use of single prec ...

High voltage semiconductor devices have found important applications in the areas of high power generation, power control, power conversion, surge protection, and industrial electronics. However, GaAs or Si based high voltage device are limited by a relatively low intrinsic breakdown voltage and,therefore, inherently suited for high power applications. We propose to develop novel high voltage hete ...

We propose a six month Phase I research program aimed at developing compliant substrates for the epitaxy of GaN and AlGaN films. We present two alternate approaches one with silicon and the other with GaAs as the starting substrate material and a unique multilayer structure to be deposited using low pressure MOCVD. We propose to investigate an approach based on the use of SIMOX substrates. These c ...

This proposal describes a new approach to laser diode drivers which combines the unique advantages of three key technologies. The innovative approach will extend the performance capabilities of laser diode systems to greater than 200 A peak pulse current, less than one nanosecond rise time, at greater than 10 KHz repetition rates. Not customarily used in laser diode drivers, the unique combinati ...

This project will investigate the use of Laser Raman Infra-Red Fiber Optic Sensor to remotely determine the chemical characteristics of advanced composite materials. The proposed research will investigate a means to measure and manage the composition and cure state of the resin matrix during an autoclave or repair process. Fourier transform Raman spectroscopy using near infrared excitation (1064 n ...

Immunization has proven to be an effective method of protecting both military and cibilian populations from disease caused by bacterial, viral, or toxic agents. The U.S. military faces the problem of protecting its personnel from incapacitation caused by exposure to agents of both natural and man-made orgin. In developing countries, immunization is the most cost-effective weapon for disease prev ...
