Design considerations for a heterodyne spatial tracking system utilizing pupil plane processing techniques and its advantages over traditional focal plane processing are described. Noise performance bounds, optimal and suboptimal local oscillator distributions, pull-in performance, and applications other than spatial tracking are discussed. Experimental verification of a one-axis closed-loop tracking system is presented.
