| 摘 要： | 利用坐标转换后的伪测量值，根据最佳线性无偏估计原理，提出一种双基地雷达目标的定位方法并给出了算法定位误差的Cramer-Rao理论下限表达式，在不同噪声条件下对算法进行仿真计算，结果表明该方法可以显著提高双基地雷达目标的定位精度，其理论下限和仿真结果都明显优于最小二乘方法。

| Abstract: | According to the principle of best linear unbiased estimation, A target localization algorithm for bistatic radar was proposed by pseudo measuring value after coordinate conversion. The expression of the Cramer-Rao lower bound for bistatic radar was given. The numerical simulation of the algorithm was carried out at different noise conditions. Simulation results show that the target localization accuracy for bistatic radar is effectively improved, and the Cramer-Rao lower bound and simulation results are better than that of a weighted least square method. |
