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。
準確識彆來襲魚雷的製導方式是水麵艦艇在魚雷防禦過程中的重大難題之一。引入來襲魚雷纍積方位變化量,在從髮現魚雷報警到自導開機這段時間內纍積魚雷的方位變化,併用最小二乘擬閤得到纍積方位變化量麯線。通過大量倣真可以構建魚雷纍積方位變化量數據庫。最後估計瞭聲自導魚雷、尾流自導魚雷和線導魚雷在魚雷相對于本艦的不同舷角下兩兩區分時魚雷和本艦的距離和區分時間。倣真結果能為水麵艦艇的魚雷防禦提供有益參攷。

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.
