摘要
研究了双机被动定位系统的最优传感器配置问题。在目标到我机的距离给定及最小圆概率误差准则下,得出了一些有意义的结论。研究表明,最优传感器配置与双机距离以及双机和目标形成的交汇角有关系,最优双机配置应满足双机距离D为我机与目标距离D1的1～1.2倍之间,构成交汇角β在90°-θ1/2<β<90°之间。得出的结论在双机被动传感器的优化配置进而提高目标定位精度方面,具有一定的理论和实际意义。
Optimum deployment in double-plane passive location system is concerned.Giving the distance of target and my plane and in the sense of the minimum Circular Error Probability （CEP）,some significant conclusions are given.The research indicates that the optimum sensors deployment is dependent on the distance of two planes and the cut angle of two planes and target.The optimum deployment should satisfy that the two planes distance D is 1～1.2 times of the distance of my plane and target D1,and the formed cut angle is in 90-1/2 90.These conclusions can be applied for reference in optimal deployment of double passive sensors to obtain high location accuracy.
