摘　　要：通过对相控阵天线工作机理进行分析,提出了基于雷达作用距离的相控阵天线毁伤判据与毁伤准则。建立AN/SPY-1D舰载多功能相控阵雷达天线模型,依据毁伤准则进行仿真评估分析,得到针对天线的毁伤分析结果。结果表明:对于AN/SPY-1D天线,当阵元毁伤比例超过50%时,雷达失效;同时对天线边缘区域阵元的毁伤将进一步造成雷达波束宽度的增加、分辨能力的降低。The working mechanism of phased array antenna is analyzed.The damage criterion of phased array antenna based on radar working distance are proposed.The model of AN/SPY-1 D shipborne multi-function phased array radar antenna is given.And the damage according to the damage criteria is analyzed.Damage results for a typical phased array antenna are obtained.
