摘　　要：对于用多台光电经纬仪进行交会测量获取空中目标给出了一种定位方法。利用所求目标位置估计点到各个观测站定位视线的距离和最小,先求出两站定位的目标坐标,然后以每两站交会测量方差的倒数为权,将所有的交会测量结果进行融合处理,即可得目标坐标。仿真结果表明,新方法有效地提高了定位的精度及稳定性。A location method is given for trajectory measurement by multi-photoelectric theodolites intersection,the concrete method is using the sum of distance among target position estimation and location lines of observers reach the minimum,deriving the location of the target by two stations,making reciprocal of each two photoelectric theodolites intersection precision as weight to get track or position of aerial target,the goal coordinate can be gained.The simulation results show that the new method is effective for improving the positioning accuracy and stability.
