Analysis on Effect of Amplitude-Phase Errors for Performance of Sonar Uniform Linear Array

Amplitude-Phase errors are important factors that restrict the performance of Sonar array. This paper establishes the model of uniform linear array (ULA) with amplitude-phase errors, and puts forward the method of statistical numeration combining with computer simulation. This method analyzes the effect on the performance of ULA with Amplitude-Phase Errors and element failure through calculating the statistical character of the radiation pattern of ULA. The analysis of theory is true through simulation proving.
