Abstract

We describe an acousto-optic signal processor which simultaneously determines target range, velocity (Doppler shift) and angle-of-arrival from pulsed Doppler radar signals. The two-dimensional processor combines a two-channel acousto-optic time-integrating correlator fed with radar signals from two antennas with an orthogonal acousto-optic time-integrating spectrum analyzer to simultaneously display target range, Doppler, and angle-of-arrival in orthogonal spatial dimensions on a two-dimensional photodetector array. By combining the pulsed Doppler and angle-of-arrival signal processing functions in a single acousto-optic processor, a compact, low power consuming package is possible.
