Study of Optical Switch Crosstalk and Its Influence on Optically Controlled Phased Array Radar System
光开关串扰及其对光控相控阵列系统的影响研究

In this paper, numerical simulation models of crosstalk for optical switch in time-delay beamforming network and of optically phased array are built. Based on the computer simulation, influences of crosstalk on pattern, including pointing deviation and sidelobe level, and on compression of LFM received by an array are studied. Simulation results indicate that the crosstalk ratio in optical switch must be less than 20dB.
