Paper Abstract

We consider an analog (linear) heterodyned linear algebraic optical processor for adaptive phased array radar (APAR). Its use in solving the discrete steepest descent (DSD) algorithm is considered. New stability and performance measure expressions are used (that relate the scenario and the processor's accuracy) and their verification is obtained by scenario tests. Extensions to more complex problems by terminating the number of iterations and by matrix preconditioning are discussed and demonstrated.
