摘要
阐述了互谱定向技术与能量积分定距技术的基本原理,提出了结合这2种技术精确提取末程目标空间尺度回波特征信息的方法。在此基础上,深入分析了悬浮式诱饵、拖曳式诱饵和潜艇的空间尺度特征,并采用获取的鱼雷攻击点源靶、水平尺度靶和空间尺度靶的试验数据进行了仿真验证,结果表明,精确提取目标空间尺度回波特征信息是可以在末程有效对抗声诱饵并识别潜艇的。
Based on the basic theories of cross-spectrum direction and energy integral distance measurement, a method to get echo features of target space dimension at last stage of torpedo range was presented. The space dimension features of fixed decoy, towed decoy and submarine were analyzed, and simulations were carried out by using the trial data from torpedo attacking point target, horizontal dimension target, and space dimension target. The simulation results indicate that precise space dimension echo features can be applied to effectively distinguish submarine from underwater acoustic decoy at last stage of torpedo range.
