摘　　要：交叉定位是一种利用多站角度信息进行解算获得目标距离信息的方法,利用双站即可完成对目标的三维定位,但此时的误差分布特性和定位精度较差。在多站系统中,可以利用目标的冗余信息进行数据融合,以改善雷达交叉定位系统中交叉定位误差分布特性和定位精度,提出了基于交会角的多站交叉定位融合算法,仿真结果给出了融合前后的定位误差分布图。与以往的方法相比,此方法计算量小,实时性较好。The cross-location based on direction measurement by multiple-radar is a method to get the distance information of the target.The precision of coordination and the performance of error distribution in system of two-radar cross-location are bad.In multiple-radar system,we can use the target＇s redundant information to fuse data.That can improve the precision of coordination and the performance of error distribution in system of multiple-radar cross-location.The paper advances an algorithm of weighted data fusion in system of multiple-radar cross-location based on rendezvous angle.The simulation results give pictures of error distribution with and without data fusion.Compared with the older method,the computational effort of this method is little and the real-time is better.
