摘　　要：针对常规拖线阵声呐存在的左右舷模糊问题,提出了一种将平台机动与目标跟踪相结合的拖线阵左右舷分辨方法,利用镜像产生左右舷目标对,根据真实的跟踪目标及其镜像目标的速度差来自动判决目标左右舷。通过仿真分析,对于10 km距离以上的目标,不管位于左舷还是右舷,平台通过小角度转向5°,经过2个扫描周期,真实的跟踪目标与其镜像目标的速度差异将大于5 m·s-1,可以较好地区分目标的左右舷,两个跟踪目标的方位变化差也可作为辅助参考。该方法在工程实践上具有一定的应用前景与指导意义。To solve the port-starboard fuzzy problem in conventional towed array sonar,a port-starboard discrimination method based on platform maneuver and target tracking is proposed.A mirror target is generated firstly,and a port-starboard target pair is formed.The port-starboard discrimination is realized by the velocity difference between the real target and its mirror target.The simulation results show that,if the target is over more than 10 km away,and whether it is on port or starboard,the velocity difference between the real target and its mirror target will be greater than 5 m·s-1 in two scanning periods after the platform steers 5°,and so the port-starboard discrimination can be realized,moreover,the difference of azimuth variation between the two targets can be taken as an auxiliary reference.The method has a certain application prospect and guiding significance in engineering practice.
