【摘要】 在矢量阵被动声呐系统中,需要对多目标进行自动跟踪。针对如何判断目标的出现和获得跟踪多目标的起始方位,本文提出了一种利用多目标在方位历程图中的轨迹信息的时空累计效应来进行自动跟踪的方法。通过对动态方位历程图数据进行亮点提取、亮点的 Hough 变换、变换空间累加信息矩阵的峰值点提取和目标方位计算几个步骤的处理,实现了多目标的轨迹和 Hough 变换空间累加信息矩阵峰值的映射,从而获得跟踪多目标的起始方位。仿真和湖试实验数据表明,该方法能有效的实现矢量阵被动声呐系统中对多目标的自动跟踪,实现了工程上的应用。更多还原

【Abstract】 In the vector sensor array based passive sonar system,it is necessary to track multiple targets automatically.In this paper,taking advantage of the time space accumulation effect of the multiple target tracks in the bearing time history display,a method is proposed to execute the automatic multiple target tracking.The method takes several steps related with dynamic bearing time history display:distinguished beating point recognition,distinguished bearing point based Hough transform,Hough space accumulation matrix sharp peak pick-up,target bearing computation.The method makes mapping between multiple target tracks and Hough space accumulation matrix sharp peaks by which we can attain the multiple targets tracking bearings.Tests with data from lake trials and simulation experiments show that the method is efficient to track multiple target in the vector sensor array based passive sonar system.It has been applied in a sonar project.更多还原
