Abstract

This paper presents an analysis of the amplitude and phase description dispersedness influence of the entrance channels acousto-optic system which processes array signals on the accuracy of random signal frequency and arrival angle estimation in the presence of external interferences and internal noises. The dependence as static descriptions of the frequency and arrival angle estimations on the signal to interference ratio, the ratio of observation time to delay time of an acousto-optic modulator, the threshold of the level devices and amplitude and phase fluctuation dispersions of the entrance channels have been analyzed.
