针对在空战中敌机保持电磁静默情况下,我机如何获取敌机有效位置信息的问题进行研究.介绍了接收站放置在空中的双基地雷达,提出一种基于时间差—测向的目标定位方法,在测向基础上增加电磁波到达接收站的时间信息,通过测向和时间信息实现对目标的定位,给出定位的三维空间结构图,并分析影响定位精度的几个因素,用几何稀释精度(GDOP)分析定位精度并做出仿真.仿真结果表明测向精度比时间精度对定位误差影响大,具有一定的工程应用价值.

This paper aims at obtaining and working over airplane's valid position under the situation that enemy's machine keep electromagnetism silence in the air battle .The bistatic radar with the receiver deployed in a platform is introduced. This paper gives a kind of object location method based on TDOA-direction. Which increased the time information based on the direction to achieve location of the target,the three-dimensional configuration is provided. The main factors which effect direction accuracy are analyzed. The location precision is analyzed with geometric dilution of precision( GDOP)and the simulation is given.Based on the analysis of simulation results,the direction precision has more infection for location error than the time precision. It is simpler to apply in practice.
