摘　　要：针对行进间工作时由于雷达与目标的相对运动,阵面坐标系下的点迹无法进行关联滤波的问题,本文梳理了一种在行进间工作时对点迹数据的补偿方法,根据北斗定位系统以及惯导所测得的信息对阵面坐标系下的点迹信息进行坐标转换和误差补偿,最终得到目标在CGC2000坐标系下的经纬高信息。经过仿真与实测数据分析验证了该方法的有效性,同时分析了雷达测量精度对最终定位精度的影响。Addressing the problem of uncorrelated filtering of point targets in motion due to the relative motion between the radar and the target in the moving mode,a compensation method was presented for point target data in the array coordinate system.Based on the information obtained from the BeiDou positioning system and the inertial navigation system,the point target information in the array coordinate system was transformed and compensated for errors,ultimately yielding the latitude,longitude,and altitude information of the target in the CGC2000 coordinate system.The effectiveness of the method has been verified through simulation and analysis of real measurement data,and the influence of radar measurement accuracy on final positioning accuracy has also been analyzed.
