The Weapons Sciences Directorate of the U.S. Army Missile Command has been directly involved in research and development of optical processing technology for several years. Extensive publications have described developments in several key areas of research. Current efforts are aimed toward military applications, for which optical processing offers great potential for improved speed and performance in automatic target detection, location, and recognition. Research is directed toward overcoming the remaining technical issues. Topics of investigation include: spatial light modulator performance and use; photorefractive materials for datastorage; Vander Lugt, joint transform, and acousto-optic correlator designs; neural network implementations for morphological transforms, region and texture segmentation, rapid training techniques; and composite filter design, development, and implementation. This paper describes progress and accomplishments in some of these areas, with projections for future work.
The United States Department of Energy's Special Technologies Laboratory (STL) has been actively involved with ground penetrating radar technology since 1968. Throughout this time period, a variety of technical ap...

ISO/MPEG has specified an algorithm for compression of video sequences at 1.5 Mbit/s. Meanwhile, additional features must be provided by the decoding system in order to build interactive applications. Support of special modes (slow, reverse, fast) and direct interfacing with graphical and video systems give an added value to the global system. In this paper, we describe a one chip MPEG1 video decoder, DIVA (Decoder for Interactive Video Applications) dedicated to interactive applications. It implements the decoding of MPEG core bitstream and is able to decode a compressed video bitstream at up to 5 Mbit/s. The architecture is organized around a single memory bank of DRAMs used in fast page mode to reach the performances required by the algorithm. After decoding, output pictures are resampled at CCIR 601 resolution and can be generated at 13.5 MHz for interlaced systems or at 25.175 MHz for computer (VGA) PC systems. An instruction set was developed in order to drive the chip so that an application can load instructions in the decoder well in advance before their execution, thus releasing the CPU from the scheduling task. DIVA was designed with an ASIC approach in a 0.8 micron technology. The chip contains 600,000 transistors in a die size of 11 X 11 sq mm and dissipates 1.3 Watt at 27 MHz.

The threat to air defence system is constantly changing because of the developments in aircraft, weapons and ECM technology. Paralleling the development of the threat there is a development of air defence systems. advances in fibre optic data processing techniques have made possible to implement the technology in air defence. The purpose of this paper is to survey the signal processing techniques presently implemented in modern air defence and those which are likely to be applied in the future years.< >
