摘　　要：为解决高技术战争中防空武器系统对隐身目标的探测问题,将临近空间作战领域与收发分置体制相结合,提出了一种基于临近空间作战平台的双基地雷达反隐身技术。根据典型隐身目标F-117A的缩比模型,利用GRECO电磁仿真软件计算出其C波段的双站RCS特性曲线;采用一种新的网格剖分方法,对临近空间双基地雷达探测隐身目标F-117A的范围进行了计算和仿真;同时在相同条件下与单站雷达、地面双基地雷达的探测范围进行了仿真对比,验证了临近空间双基地雷达探测隐身目标的先进性;最后指出了它在未来防空作战中的应用前景。In order to solve the problem of the aerial defense system in detecting stealth targets, a new method is presented which combines near space operating area with receiving/transmitting mechanism, i. e. , a bistatic radar system based on the near space operational platform. Taking F-117A model as example,the bistatic radar RCS is simulated with the electromagnetism software in the C waveband. The detection range of the near space bistatic radar to anti-stealth is simulated based on the new gridding analysis method. The effect of the method is compared with the detection ranges of the monostatic radar and ground-based bistatic radar,and the advantages of the near-space based bistatic radar in detecting stealth targets are validated. The application prospect of it in the future aerial defense is presented.
