This Phase I SBIR proposal represents a cooperative effort between Atlantic Aerospace Electronics Corporation and Texas Instruments, Inc. It is aimed at developing and assessing the feasibility of two innovative and fundamentally different approaches to track-before-detect (TBD) processing for passive airborne IRTW and IRST sensors. TBD processing techniques are required for airborne surveillance ...

This Phase I SBIR proposal is aimed at developing and assessing the feasibility of Image Processing Techniques to distinguish between submarine and non-submarine in Active Sonar Echoes. Image Processing Techniques have proven to be highly effective in detecting objects in cluttered backgrounds using other sensors such as Synthetic Aperture Radar, Infrared Sensors, and Lasers. The highly reverberan ...

A NEW APPROACH IS PROPOSED FOR OCEANOGRAPHIC REMOTE SENSING WITH DUAL USE APPLICATIONS IN MINE HUNTING, OCEAN BOTTOM MAPPING, AND SEA FLOOR REMOTE SENSING. THE WEAVER IS A SONAR SYSTEM INTENDED TO DETECT, LOCALIZE, AND CLASSIFY SEAFLOOR BOTTOM LAYING TARGETS, DISCRIMINATING MAN-MADE ITEMS FROM NATURAL ONES IN THE PRESENCE OF NATURAL CLUTTER; IT EXPLOITS HERETOFORE OVERLOOKED TARGET-PHYSICS BASED C ...

Tactiling is the name given to a method of tactually supplementing speechreading. According to this method a deaf speechreader places his hand on a talker's shoulder with his fingers lightly against the neck; thus, the talker will obtain clues relating to voicing and dynamic speech intensity. The method was invented by a postlingually deaf Swedish male and has been studied since 1986 by several in ...

This project will develop and demonstrate a design for a wavelet-based compression system that will support the tranmission of video and still data bia UHF satellite communication channels and twisted-pair cuircuits. The system will feature real-time teleconferecing and the ability to rapidly transmit still imagery and video material at user selectable quality levels. The project will focus on eng ...

Subclutter visibility may be achieved using wavelets and wavepacket methodss. Wavelets offer the ability to separate features based on scale. Wavepackets and the best-basis algorithm offer the further advantage of adaptability; bases adapt to the signal to provide optimum signal representation. We propose to develop techniques for separting low altitude, low observable targets from clutter on the ...

Digital imagery is an increasingly prevalent in the computerized workplace; however, the increasing volume of this data is stressing storage and communications systems. One of the most competitive solutions to these stresses is wavelet-based data compression. A wide variety of wavelet image compression methods exists, and given an application, there is a need to compare different methods before ...
