摘　　要：多个被动测向站组成的传感器网络,能够实现较大范围内纯方位目标的角度探测.结合相关的算法,便可以通过多站传感器获得的目标方位数据,在多站的交叠区域内实现对目标的定位以及跟踪。但是,实现目标的定位以及跟踪,首先要确定来自不同传感器的目标信息之间的对应关系,即首先要实现多站纯方位目标之间的航迹关联。论文基于Hough变换的方法,提出了一种多站纯方位目标的航迹关联算法。通过仿真结果表明,在多站的交叉探测区域内,利用该算法,能够很好的实现多个纯方位目标之间的航迹关联。The sensor network composed of a plurality of passive sensors can complete the angle detecting of the target in a relatively wide area. With the algorithm, the target azimuth data obtained by multi - sensors can be used to achieve the target location and track- ing in the overlapping area. However, to achieve the goal of positioning and tracking, it is necessary to get the correspondence between the target information from different sensors, that is track association of bearings - only targets. Based on the method of Hough trans- form, this paper presents a track correlation algorithm for multi - station hearings - only targets. Simulation results show that the track correlation between multiple hearings - only targets can be achieved in the overlapping area of multi - station with the al,,orithm.
