Abstract

Coherent optical processing can be effectively used to detect moving objects against a background of fixed objects and noise. If done digitally, the task can require a large amount of processing power. The optical approach is to do pattern recognition in the frequency plane of the time-integrated sky image. A spatial filter, matched to the spectral energy distribution of the moving objects, rotates in the frequency plane. Earlier experiments established the validity of the approach'. The processor has since been refined, simplified and implemented in an optical/digital configuration. A small digital computer (PDP 11/03) provides simulated input data, controls the operation of the optical processor, and displays the results.
