Abstract
An electro-optical system for performing the computation of the radar ambiguity function or other similar mathematical function using the parallel processing capability of optical systems including a photo-responsive, real-time programmable mask for storing a set of sample values {s.sub.p }. A light source is positioned to illuminate the mask and have its intensity modulated as a function of the sample values {s.sub.p }. The image from the programmable mask is transferred to a CCD photo-sensor array that is clocked in synchronism with the light pulse outputs of the light emitting diode to give rise to electro-optical products which are integrated in the CCD structure to yield the ambiguity or other similar mathematical function.
