外辐射源雷达系统优化布站方法研究

Study on the Method of Optimizing the Distribution of Passive Radar

在外辐射源雷达系统中,不同几何布局的雷达收发站对同一空间位置上的目标,其定位精度是不同的;同样,在雷达收发站几何布局已定的情况下,该系统对不同空间位置上目标的定位精度分布也是不同的。因此研究雷达收发站几何布局与目标定位精度分布之间的关系,对于有效使用不同几何布局的外辐射源雷达系统,精确地对目标进行探测和定位是十分必要的。文章通过MATLAB仿真分析了几种Tn-R型外辐射源雷达系统的定位精度几何稀释,并由此提出了优化布站的方法 。

In passive radar system,for the same space position,different geometric distribution of the radar transmitter and receiver has different location accuracy.Similarly,for the determined distribution,different space position has different location accuracy.Therefore,it’s necessary to study the relationship between the geometric distribution and the accuracy of the targets,which is effective for the use of different passive radar for precise detection.In this paper,the geometrical dilution of precision(GDOP)simulation of several Tn-R passive radar system is analyzed by MATLAB,and thus a method of optimizing the distribution of the stations is proposed.
