首先介绍了双基地雷达距离解算模型,并对其距离解算误差进行仿真,结果表明双基地雷达在基线附近存在无法高精度定位的缺点。然后介绍了选优和LS两种数据融合算法,通过对两种优化算法进行系统仿真,结果表明,这两种算法均可获得较高的距离解算精度,很大程度上提高了基线附近定位精度,改善了系统的定位性能。

Firstly, the range solving model of bistatic guidance radar is introduced, and the range solving error is simulated. The simulation results show that the bistatic guidance radar is inability to position finding related to the base line by high precision. Then two data fusion algorithms on excellent selected and LS are introduced. The simulations on the two data fusion algorithms show that both the optimization methods could get the high range solving precision enhance the systematic location perform and greatly improve the position accuracy related to the areas around base line.
