Paper Abstract

This paper describes a novel pulse compressor concept based on optical coherent detection and associated implementation issues imposed by electro-optical component characteristics. The concept was developed to support pulse compression of wideband linear frequency modulation (LFM) waveforms in noncooperative bistatic/multistatic radar applications. Waveform bandwidths in excess of 1 GHz can be accommodated. Coherent optical detection is used to implement difference-mixing for subsequent digital active-correlation processing. This technique is noncooperative in that it requires no dedicated external reference or timing signals to be provided by the illuminating radar. Rather, the necessary reference signal is derived from intercepting the radar sidelobe emissions. Noncooperative narrow-band processing techniques have been developed, but the capability of this optical processing architecture to accommodate wideband signals appears unique.
