Paper Abstract

A simple, robust architecture is proposed for adaptive antenna array processing using an acousto-optic Bragg cell array and a photorefractive material in a time integrating correlator configuration. A Bragg cell array is used for computing correlation coefficients and for forming the tapped delay line filter. The resulting processor is very compact since it can be implemented as a monolithic structure by using the same material for the acousto-optic interaction and the photorefractive implementation of adaptive tap weights. Equations are derived for expected dynamic range, and time response.
