基于累积方位变化量的来袭鱼雷制导方式识别

摘要

To recognize the guidance type of incoming torpedo exactly is one of significant problems in surface ship's defense action.Introducing cumulative azimuth variation of incoming torpedo, accumulating the azimuth variation from torpedo alert to homing boot,the cumulative azimuth variation curves are obtained by least squares fitting. The cumulative azimuth variation database can be constructed through enormous simulation.Finally,the time and the distance between torpedo and ship in which acoustic homing torpedo,wake homing torpedo and wire-guided torpedo can be distinguished pairwise are estimated.The simulation results can provide helpful references for surface ship's defense towards incoming torpedo.%准确识别来袭鱼雷的制导方式是水面舰艇在鱼雷防御过程中的重大难题之一。引入来袭鱼雷累积方位变化量，在从发现鱼雷报警到自导开机这段时间内累积鱼雷的方位变化，并用最小二乘拟合得到累积方位变化量曲线。通过大量仿真可以构建鱼雷累积方位变化量数据库。最后估计了声自导鱼雷、尾流自导鱼雷和线导鱼雷在鱼雷相对于本舰的不同舷角下两两区分时鱼雷和本舰的距离和区分时间。仿真结果能为水面舰艇的鱼雷防御提供有益参考。
