摘　　要：角反射器作为一种反雷达探测的无源干扰设备具有很强的雷达回波特性。根据重要目标的散射中心模型指导排布角反射器阵列,可以更好地模拟目标的雷达特征以实现干扰,具有重要的军事应用前景。为了合理地排布角反射器阵列以模拟实际场景中重要目标的电磁散射特性,本文基于弹跳射线法快速成像技术构建了复杂场景目标复合电磁散射模型,并提出了基于目标属性散射中心模型的角反射器阵列优化排布方法。仿真实验分析了在不同雷达入射角度下不同类型角反射器的电磁散射特性。同时结合不同干扰效果评价指标,验证了在多雷达入射角度下本文所设计角反射器阵列的目标干扰效果在85%以上,角反射器阵列作为无源干扰具备保护重要目标的能力。The corner reflector as a passive jamming device for anti-radar detection has strong radar echo characteristics.Arranging the corner reflector array according to the scattering center model of an important target can better simulate the radar characteristics of the target to achieve jamming,which has important military application prospects.In order to reasonably arrange the corner reflector arrays to simulate the electromagnetic scattering characteristics of the important targets in the actual scene,this paper constructs a complex electromagnetic scattering model of the target in the complex scene based on the fast imaging technology of the bounce ray method,and proposes an optimal arrangement method of the corner reflector arrays based on the scattering center model of the target attributes.Simulation experiments analyze the electromagnetic scattering characteristics of different types of corner reflectors under different radar incidence angles.At the same time,combined with different interference effect evaluation indexes,the simulation experiment verifies that the target interference effect of the corner reflector array designed in this paper is more than 85%under multiple radar incidence angles,and the corner reflector array has the ability to protect important targets as passive interference.
