| 摘 要： | 针对室外近地雷达横截面(RCS)测试场测量结果易受多路径干扰影响的问题,利用射线跟踪技术,综合考虑了信号直射、地面反射和刀边衍射3种因素,建立了单刀刃型障碍信号传输损耗预测模型,推导出了单刀刃型雷达栅信号传输衰落的数学表达式.结合某单位外场数据,对近地信号传输损耗预测模型进行了仿真分析,提出了一种新的单刀刃型雷达栅高度选取原则,根据优化结果进行了工程实现.实测结果证明了文中所述模型的实用性和有效性.

| Abstract: | To deal with the problem that the radar cross section(RCS) outdoor measurement result is vulnerable to the multi-path interference with low elevation,a radio propagation loss prediction model for outdoor RCS range is presented with the use of ray tracing technique.The direct signal,ground reflection signal and edge diffraction signal were considered in the presented model.The general expression of the path transmission attenuation with single knife edge fence was derived in detail.Numerical simulation and a... |
