Abstract
本发明涉及一种基于Hough变换的多维参数的检测前跟踪方法,包括以下步骤:初始化,确定目标航迹起始,并作为初次检测结果;从第3次检测开始循环;根据上一次检测结果与本次提取的特征参数作差和判决门限比较,进行判决;根据判决结果,对目标进行跟踪,当运动目标的其中某一特征参数比较发散时,执行滤波,否则,直接执行Hough变换,进行能量积累;根据目标积累能量和积累门限进行比较,自适应更新判决门限;通过积累门限的目标,作为最终的检测结果,并开始下一次循环。本发明基于Hough变换的多维参数的检测前跟踪方法避免预估航迹偏离实际,并且消除虚假航迹;提升了雷达对多运动目标的检测、跟踪和区分性能
