Multichannel optical correlator for radar signal processing
Abstract
A multichannel coherent optical processor for radar signals is described in which pulse compression is achieved by matched spatial filtering. The optical system can be used for phased-array, linear-frequency modulated-pulse-burst, or other radar systems. Its application to linear phased-array signal processing is discussed in depth. From the output optical pattern, one can obtain data on the target's fine range and azimuth (for a phased array) or fine range and Doppler (for a pulse burst radar) etc.
