摘　　要：在研究多部两坐标雷达组网对目标的三维空间定位问题时 ,给出了一种利用WLS(WeightedLeastSquare)算法进行数据融合处理的方法 ,推导了定位精度公式 ,并且研究了在不同条件下的定位精度几何稀释和高度误差。仿真结果表明此方法可以有效地提高组网雷达的定位精度。此公式可以推广到三站以上的组网雷达系统中 ,在雷达缺乏高度测量的情况下 。An algorithm, WLS(Weighted Least Square),is presented to research the 3 D locating precision of multi 2D radar network to target. The formula of the locating accuracy is deduced. Geometric Dilution of Precision (GDOP) and height error are discussed under different conditions. Simulation results indicate that method can improve locating accuracy of 2D radar network effectively. This formula can be extended to other radar networks been possessed of three or more radars too. This method is able to realizes effective estimation of the position and height of the target without its height data.
