Optical Processor Evaluation.

Abstract

This report evaluates several different algorithms for use in a hybrid electro-optical signal processor. The processor is intended to perform adaptive interference cancellation in radar systems. A personal computer is used to take in an optically formed correlation signal, and compute delays and weights which are used to optically form an estimate of the interfering signal. This report concerns the algorithm that will reside within the personal computer to accomplish this task. The algorithms considered include parabolic interpolation, steepest descent, conjugate direction, simulated annealing, and two neural network approaches. Relative advantages and disadvantages of each algorithm are discussed.
