Investigation of Electro-Acoustic Technology for Topographic Applications.

Abstract

Studies were made of surface acoustic wave (SAW) and acousto-optical (A/O) devices for image processing and feature extraction from images. In the report, each device is defined, signal processing with the devices is discussed, and topographic applications for the devices are reviewed. The report concludes that the devices may be used in signal processing and decision circuitry for topographic systems, for example, distance measurement equipment (DME), radar return receivers, and image analyzers.
