摘　　要：为了提升隐身飞机平台末端防护能力,本文通过分析多种角反射器及隐身飞机平台的RCS特性,提出了一种新型角反射器阵列,其由四级角反射器叠加组成.基于CST软件对阵列全角域雷达散射特性进行了建模与仿真分析,制作了模型样件且在微波暗室远场环境内进行了RCS测试,并与仿真结果进行对比验证,得到了该角反射器阵列的雷达散射特性.该角反射器阵列结构具有前向RCS小、前侧向及正侧向RCS大的特点,与隐身飞机平台特性相似,整体结构呈流线型并且在阵列尾部有折叠尾翼,能够从飞机平台进行投放并保持飞行,具备较好的干扰应用价值.In order to support the improvement of the end protection capability of stealth aircraft platform,a new corner reflector array is proposed by analyzing the radar cross section(RCS)characteristics of various corner reflectors and stealth aircraft platform.The array structure is composed of four groups of corner reflectors superposed.Meanwhile,the full-angular radar scattering characteristics are modeled and simulated based on CST software.The model sample is made the RCS test is carried out in the far field environment of the microwave darkroom.The simulation results are compared and verified,and the radar scattering characteristics of the corner reflector array are obtained.The structure of the corner reflector array has the characteristics of small forward RCS and large forward and positive side RCS,which can be dropped from the aircraft platform and keep flying,thus it has good interference application value.
