COMPACT PHASE-CONJUGATING CORRELATOR - SIMULATION AND EXPERIMENTAL-ANALYSIS

A simulation and experimental investigation of a recently proposed, co mpact, phase-conjugating correlator is undertaken. The effects of nois e and other distortions in the input image and in the correlator filte r plane are considered. As with other phase-only designs, the phase-co njugating correlator is sensitive to distortion of the input image whi le being robust in the presence of filter-plane distortions; this robu stness is enhanced by the phase-conjugating property of the design.
