Abstract

Accusto-optic (Bragg cell) devices are able to perform a wide range of signal processing functions including correlation and spectrum analysis. This paper discusses three Bragg cell architectures which have applications in electronic warfare, radar, lidar and spread spectrum communications. These are a 100 MHz bandwidth time-integrating correlator (TIC), a two-dimensional optical processor for generating the cross-ambiguity function (OAF) and an optical multi path analyser. This paper is illustrated by examples of hardware constructed by Marconi Defence Systems.
