常规的单线阵声呐存在左右舷模糊问题，严重制约了其使用效能。本文提出一种基于目标跟踪的单线阵左右舷分辨方法，首先对目标进行镜像处理，形成左右舷“目标对”，然后将平台机动与目标跟踪结合起来，通过跟踪目标的速度差来自动判决目标左右舷。仿真结果表明，平台通过小角度机动，经过2个扫描周期就可以很好区分目标左右舷，验证本方法的有效性与可行性，具有一定的工程应用价值。
The port-starboard fuzzy is a problem in the traditional single towed array, by which the effectiveness is affected. In this paper, a port-starboard discrimination method of single towed array based on target tracking is proposed, a mirror target is generated firstly, and a port-starboard target pair is formed, then the target tracking is combined by the platform maneuver, the port-starboard discrimination is realized by the difference of target velocity between the two targets. The simulation results show that, the port-starboard discrimination can be realized in two scanning periods after the platform turns a small angle, the effectiveness and practicability of the proposed method is verified, which has a certain engineering value.
