主动声尾流自导导引过程中信息获取与应用

Acquirement and Application of Information During Guidance of Active Wake Acoustic Homing Torpedo

在用主动声尾流自导导引跟踪目标舰尾流的过程中,鱼雷通过进出目标尾流,可获得目标走向以及鱼雷和目标相对关系等信息,对这些信息的进一步处理和使用将有利于优化导引弹道、降低鱼雷航程损失、提高命中概率,特别是有利于对规避机动目标、人工变形尾流等对抗措施进行反对抗。本文研究了在主动声尾流自导导引过程中获取信息的算法以及这些信息的应用,并进行了数学仿真验证,为尾流自导导引弹道的优化和反对抗措施的设计提供了有效方法,可供主动声尾流自导鱼雷弹道优化设计参考。

During the process of guidance, active wake acoustic homing torpedo can get the information about target orientation and the relative orientation of the torpedo and target by entering and leaving the wake. Further processing of this information will be beneficial to reducing endurance loss and increasing hit probability via the trajectory optimization, especially to coping with the countermeasures such as evading maneuver target and wake bifurcation by means of trajectory design. An algorithm to obtain and apply the information is proposed and verified by mathematical simulation.
