摘要
为满足雷达对抗隐身目标的需求,建立了单站电磁波入射角度的模型。利用电磁仿真软件XFDTD计算和分析了典型隐身目标F-117A飞机的单站雷达截面积,包括电磁波在头向入射、鼻椎向入射、正侧向入射、尾向入射条件下单站雷达截面积随频率变化的特性。通过对仿真结果的分析得出了有利于单基地雷达反隐身的入射方向和工作频段等结论及数据,具有一定的理论参考价值。
In order to meet the needs to defense stealth targets, the model for electromagnetic wave incident angle of mono-radar is built, the radar cross sectional area of F-117A stealth fighter under mono-radar condition is analyzed with XFDTD, under different angle and frequency conditions. Some valuable data and conclusions are obtained, which can be provided as theoretical reference.
