摘　　要：针对雷达方位误差标定问题,提出了一种基于多直线融合的雷达误差标定算法,算法首先利用航迹相似度匹配原则选择雷达与ADS-B获得的匹配数据集对;然后基于直线可信度判断算法对ADS-B数据集进行直线集拆解,与该直线集对应完成雷达数据集的拆解,进而计算直线对的夹角集;最后结合直线的可信度对夹角集进行统计平均,获得雷达标定误差角。该算法很好地克服了目前雷达标定过程中对航迹特性要求高、标定航迹选择难的问题。经实装测试表明,该方法可以高效快捷地对雷达进行标定,有效保证了雷达侦察能力的完成。In this paper,a new method for correcting radar calibration error is proposed based on the fusion of multiple straight lines.This algorithm uses the similarity match to choose the tracks from the radar and the ADS-B.Then the chosen ADS-B track is split by the straight line reliability judgment algorithm.The chosen track corresponding to the ADS-B track is split and the intersection angle set can be calculated.Finally,the statistical averaging of the intersection angle set is calculated to obtain the radar calibration error.This algorithm overcomes the high requirements on track property of radar calibration and the difficulty to select calibration track.
