Abstract

Nowadays different modifications of acoustooptic matrix-vector processor (AOMVP) are applied to the linear-algebra problems, spectrum analysis of radio signals, organization of reconfigurable interconnections, digital multiplication, neural networks' . One of the most promising AOMVP applications is parallel signal processing in synthetic aperture radar (SJ)2 Nevertheless, the advantages of optical information processing may be plagued because of the limited accuracy of computations in AOMVP, which are basically of analog nature. Therefore, theoretical and experimental investigation of computation accuracy is of considerable importance for SAR processor designers. Below the performance of AOMVP-based SA.R processor is analyzed in regard to the quality of fabrication, tuning, and adjustment of AOMTP elements, which is characterized with the totality of their noise and error root-mean-squares (rms's), as well as the value of crosstalk among the processing channels. The optical scheme of AOMVP experimental model intended for high speed processing of radar signals with using ofa multichannel acoustooptic modulator (MAOM) is presented
