针对多机动站交叉定位系统观测站具有机动能力的应用特点,从测向交叉定位技术的定位原理入手,分析了影响定位精度的因素,以4 站交叉定位系统为例,按目标大致分布区域已知且布设阵地条件不受限制、基于任务需求观测站需机动的随机布站两种典型应用场景,提出了根据目标分布区域优化布站阵型、根据既定阵型优化数据处理算法两种定位优化方法。在不额外增加观测站的条件下,有效提升定位精度、增大有效定位区域。该方法成本代价小、技术难度低、定位效果好,具有较好的应用推广价值。

Considering the stations′motility feature of the motility multi-station cross location System, the factors which affecting location accuracy have been analyzed through the principle of the direction finding cross location technology. Taking four stations cross location system for instance, because of two typical applying scenes of the target distribution known and station unlimited, as well as random station layout while station moved, the optimizing station layout according to target distribution and optimizing data processing algorithm according to the fixed station layout have been advanced. The location accuracy and the location area have been optimized without adding extra station. The method is worth to popularizing because of low cost, low difficulty and fine location result.
