摘　　要：针对基于α-β滤波的高频地波雷达海上目标航迹跟踪方法跟踪精度较低、工程适用性较差的问题,提出了一种极坐标下α-β滤波自适应系数选取方法,该方法有效利用了高频地波雷达目标量测参数的特点,能够在跟踪过程中根据实际量测对滤波系数进行自适应调整。利用仿真及实测地波雷达数据以及同步AIS航迹对提出方法的航迹跟踪性能进行了实验验证,并与现有自适应系数选取方法的跟踪性能进行了对比,结果表明,本文方法能够得到平滑、持续的航迹输出,跟踪距离远,跟踪率及跟踪精度高。Traditional maritime target tracking based on the alpha-beta filtering for high frequency surface wave radar（HFSWR）shows low accuracy and poor engineering applicability.To address this issue,an adaptive coefficient selection method for the alpha-beta filter is proposed,in which the property of the measured data is utilized for adjusting the filtering parameters adaptively.Simulation analysis and real data tracking experiments are carried out to verify the efficiency of the proposed method.Matched detection results from Automatic Identification System（AIS）tracking information are adopted as the evaluation criteria and existing adaptive coefficients selection methods are adopted for comparisons.Experimental results demonstrate that smooth and continuous tracks with long tracking range,high tracking rate and accuracy can be obtained by the proposed method.
