摘　　要：针对机载电子战中经常遇到的地形遮蔽问题,定量分析了遮蔽条件下电磁波绕射效应对机载电子战设备的影响。首先基于传统刃形单峰绕射模型提出了在地球曲率下山峰绕射高度的计算方法;然后基于Picquenard刃形多峰绕射模型提出了地球曲率下的主峰迭代搜索算法;最后利用构建的电磁波绕射模型,提出了机载电子战在地形遮蔽情况下的对抗策略。将算法嵌入模型后,通过比对仿真结果与真实试验数据,表明所提算法可适用于计算地形遮蔽对机载电子战设备的影响。In response to the terrain masking problem commonly encountered in airborne electronic warfare,a quantitative analysis method was conducted on the impact of electromagnetic wave diffraction with shielding conditions on airborne electronic warfare equipment.At first,based on traditional unimodal knife-edge diffraction model,an algorithm for calculating peak diffraction height was proposed.Then,based on Picquenard mutimodal knife-edge diffraction model,an iteration algorithm for searching main peak under earth curvature was proposed.Finally,the counter measures of airborne electronic warfare under terrain shielding condition was presented.After embedding the algorithm into the model,by comparing simulation results with real experimental data,it is shown that the proposed algorithm is suitable for calculating the impact of terrain occlusion on airborne electronic warfare equipment.
