摘　　要：在VTS系统的应用中需要对锚区内停泊的目标进行监管。在港口或码头的水域内,锚区通常位于监管区域的远端,雷达方位上的随机误差在传递到直角坐标时会使目标点迹在雷达站的切向方位上呈现摇摆的特点,并且锚区内的目标通常比较密集,所以VTS系统内的导航雷达在跟踪远区内的静态目标时会面临较大的困难。本文利用点迹杂波图生成雷达监管区域内的静态目标态势,然后将静态目标态势和目标航迹分布进行关联,并利用静态目标态势的位置信息对目标关联数据进行修正,以提高对远距离静态目标的跟踪精度。The targets berthed in the anchorage area are required to be supervised in the application of the VTS system. The anchorage area is usually located in the remote area of the supervision zone in the waters of the harbor or the dock. When the random errors in radar azimuth are sent to the rectangular coordinates,the plot swing shall occur in the tangential direction at the radar station. Usually,the targets in the anchorage area are very dense. Therefore,the navigation radar in the VTS system is faced with a difficult problem in tracking the static targets in the remote area. The static target situation in the supervision zone is generated by utilizing the plot clutter map,and then the static target situation and the target track distribution are correlated. Moreover,the correlated target data are corrected according to the location information of the static target situation to improve the tracking precision of the static targets.
