摘　　要：论文将空中目标的ADS-B测量数据作为参照系,提出并采用单雷达加权直线航迹线参数估计数据配准方法,计算雷达观测数据与ADS-B配准点之间的相对系统误差,并以此结果修正雷达后续测量点坐标。试验结果表明,该方法误差估计准确,航迹修正效果理想,对于提高多雷达航迹关联准确性及航迹融合质量具有重要意义。In this article,ADS-B measurement data of aerial target is known as reference system,data registration method of single radar linear track weighted estimation is put forward,relative system error between the radar measurement data and the regis⁃trating point data of ADS-B is calculated,and the coordinates of the radar's subsequent measurement points are corrected by using this result.The experimental results show that this method is accurate in error estimation and effective in track correction,it is im⁃prove veracity of track relevancy and quality of track in multiple radars fusion.
