| 摘 要： | 多站雷达的布局直接影响距离差法目标定位的精度。首先给出多站雷达系统距离差定位的误差协方差矩阵的表达式和计算方法,然后以误差椭球体积最小为布站优化的目标,讨论了多站平面布局对空间目标定位时的优化布站方法,并在平面优化布局的基础上,推出无约束情况下的最优布局。仿真结果与理论分析一致,该结论可以推广到无源定位系统。

| Abstract: | Locating accuracy of TDOA(time difference of arrival)is depend on multiradar constellation.The expression and the calculation method of locating error covariance matrix based on the method of TDOA is proposed firstly.For the aim of minimizing the error ellipsoid volume,the mothed of optimal station constellation for target locating in multiradar system is presented.As follows from the optimal constellation on the ground,the optimal constellation without restriction results are also expounded.The computer simulation results are in accordance with the theory analysis,the conclusion can also be used in passive locating system. |
