Abstract

An architecture for an optically implemented adaptive array processor which operates in quadratic residue number systems (QRNS) is presented. The unit provides four adaptive degrees of freedom but can be expanded, through additional modular processing elements, to 12 or more degrees. Separate subprocessors construct a sample covariance matrix and solve for the complex weights via Gauss elimination and back substitution. A third subprocessor performs scaling and integer reconstruction operations through mixed radix conversion (MRC). The system uses optical clocking to operate at an internal rate of 200 MHz, and it will produce complete weight solutions approximately once per microsecond with a total latency of about 2.3 psec.
