摘　　要：针对雷达组网滤波过程中的系统误差问题,本文在双站二阶抗差估计的基础上提出了一种在三站组网情况下减少航迹滤波系统误差的三阶抗差估计方法,并探讨了在两种不同布站方式下该方法对于减少滤波系统误差的效果。仿真结果证明,该方法在第一种布站方式下能够有效减少组网滤波过程中在距离维、方位维、俯仰维测量时产生的系统误差。In view of systematic error problem in the radar network filtering process,in this paper,a method was proposed based on the two-station second-order robustness estimation that can reduce the problem of low-resolution radar in the three-station network.A third-order robust estimation method for track filtering system errors was presented,and the effect of this method on reducing filtering system errors under two different station deployment modes was discussed.The simulation results proved that this method can effectively reduce the systematic errors generated in the measurement of distance,azimuth and pitch dimensions during the network filtering process in the first station layout mode.
