Abstract

This paper analyzes and evaluates the nonlinearity of a fiber optic link in an optically controlled array. It establishes the numerical simulation model for calculating the pattern of the optically controlled phased array with fiber optic delayer at subarray. And finally, it simulates the effect of nonlinearity in the fiber optic link on the pattern of the optically controlled array antenna by computer, and gives the curves to describe the sidelobe level and mainlobe 3 dB width versus second-harmonic distortion.
