Paper Abstract

The Acousto-Optic Spectrum Analyzer (AOSA) is probably the simplest optical processor with practical value. It performs a single dimensional real-time Fourier transform using only four active components, a light source, Bragg cell, transform lens, and a photodetector array. A description of the basic operating parameters of the AOSA when used for radar signal processing is presented by comparing a traditional ray trace with a process element diagram and an electrical equivalent circuit. Selected applications and off-the-air results are included.
