Optical Matrix Inverter for Phased Array Radar

Abstract

The purpose of this study is to investigate new approaches to process the data collected by phased array antennas to achieve interference cancelling. This data processing needs to be performed with severe time constraints. A hybrid optoelectronic processor, the bimodal optical computer (BOC), was introduced. The BOC was implemented to process the phased array data. The BOC algorithm was analyzed for the convergence of the optimal weights. Convergence dependence on the errors involved in the analog optics devices, the condition number of the matrix and the strength of the jammer signal were considered. An experimental model of the BOC was built and used in solving systems of linear equations and matrix inversion. An agreement between theory and experiments is shown. Computer simulation of the BOC in interference cancelling was presented.(r.h.)
