摘要
Abstract
Phased array antenna has found wide applications due to its characteristics of the fast scanning speed and the flexible beam pointing.Since the numerous array elements,there is a great possibility of element failure.So it is necessary to carry out the analysis of damaged phased array antenna.Matlab modeling is used to obtain the intact antenna pattern and the damaged antenna pattern,and the damaged pattern is analyzed.The conclusion is reached that the closer the position of the damage array element to the center,the greater the impact on the antenna pattern.Moreover,on the basis of the failure of single array element,the antenna array is divided into five regions.The damage level is determined directly through observing the number of failure array elements in each regions.An important basis is provided for the damage assessment and the repair of the planar phased array antenna.关键词
