Abstract
An iterative optical matrix-vector processor that computes the adaptive weights for a phased array radar is described. Multidimensional adaptivity in both target angle and velocity is achieved by lexicographically ordering the antenna elements as they are fed to the optical processor. Complex weights are computed by spatial multiplexing of the vector and matrix inputs to the system. The error sources of the optical system and the convergence of the iterative algorithm are analyzed, and experimental demonstration of the accuracy and performance of the system is included. This novel processor is found to perform quite adequately and to be most appropriate for advanced multidimensional adaptive phased array radars.
