Abstract 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.
