摘要
Abstract
Array-element can fail during working usually because of various reasons .Aimming at this question ,the effects of element failure on the side-lobe level of phased array antenna are analyzed based on the model of one-dimension uni-form linear array .And the number and the distribution position of the failed elements are studied .Simulation results show that the side-lobe level will deteriorate slightly when the failed elements are located at the both ends of the array ,but it will deteriorate seriously when the failed elements are located at the middle of the array .For the 24-element uniform linear array with - 30dB side-lobe level ,the probability of the side-lobe level is higher than - 20dB exceeds 90 percents when the number of failed elements is more than 2 .关键词
