Paper Abstract

A novel channelized, hybrid time- and space-integrating acoustooptic (AO) spectrum analyzer is described. The architecture consists of two AO cells in a crossed-cell configuration. The first AO cell is a wide bandwidth device that performs space-integrating spectral analysis and channelizes signals according to carrier frequency. The second AO cell, in conjunction with a modulated source, performs time-integrating spectral analysis of the signal envelope using the chirp algorithm. One possible application of the processor is to determine the carrier frequency and pulse repetition frequency (PRF) of received radar signals.
