摘　　要：航迹起始是雷达目标跟踪的开始阶段,起始算法的准确性和执行效率对目标跟踪性能有重要影响。为了明确各种算法的特点和适用场景,文章对工程上常用的航迹起始算法进行了性能仿真。仿真结果表明,直观法适用于低密度目标场景,逻辑法和Hough变换法适用于较高密度杂波场景。仿真结果还表明,现有的三种算法不能很好地处理目标编队运动场景,编队目标精确航迹起始是下一步研究的重点。Track initiation is the beginning stage of radar target tracking.The accuracy and efficiency of the track initiation algorithm have an important impact on target tracking performance.In order to clarify the characteristics and applicable scenarios of various algorithms,the performance simulation of track initiation algorithm commonly used in engineering is carried out in this paper.The simulation results show that the heuristic rule method is suitable for low-density target scenes,while the logic-based method and Hough transform approach are suitable for high-density clutter scenes.In addition,the results show that the existing three algorithms can't deal with the target formation motion scene well,and the accurate track initiation of formation target is the focus of the next research.
