摘　　要：角反射器在舰船目标防御中发挥着重要作用,如何有效对抗角反射器干扰是当前的研究难题.以典型八面体角反阵列为例,通过电磁计算和暗室测量获得了宽带双基地散射特性数据,分析了一维距离像随观测角和双基地雷达几何结构变化的规律.结果表明当双基地角达到一定角度条件下,角反射器散射强度急剧下降,这一特性可用于抗角反射器方法设计.Corner reflector plays an important role in ship target defense.How to counter the corner reflector interference effectively is currently a difficult research problem.Taking the typical octahedral corner reflector array as an example,this paper obtains the wideband bistatic scattering data by electromagnetic calculation and anechoic chamber measurement and analyzes the change law of 1D high-resolution range profiles(HRRP)with the observation angle and the bistatic geometry.The results show that the scattering intensity of the corner reflector decreases sharply when the bistatic angle reaches certain condition,which can be used to counter the corner reflector.
