水声对抗环境下自导鱼雷自适应导引方法

随着现代水声对抗与反对抗环境的日益复杂,自导鱼雷导引律的设计需要考虑目标识别及末自导垂直命中的要求,使得传统的导引律面临新的挑战,为此提出了一种新的自导鱼雷自适应导引方法,该方法根据鱼雷与目标之间的距离调整鱼雷航向角,调整过程考虑了进行方位走向目标识别以及末自导垂直命中对导引弹道的要求,使目标舷角有利于进行目标识别及末自导垂直命中。仿真结果表明,采用该方法获得的目标舷角变化不仅满足目标识别要求,而且有利于垂直命中。

Adaptive Guidance Method of Homing Torpedo under Underwater Acoustic Countermeasure Condition

Modern acoustic countermeasure and counter-countermeasure environments become more and more complex,so it is necessary to consider target recognition and terminal guidance perpendicular hit in the design of guidance law for a homing torpedo. This paper proposes a new adaptive guidance method for a homing torpedo, in which the torpedo course angle is adjusted according to the distance between a torpedo and a target, and the target azimuth trend recognition and the requirement of guidance trajectory for terminal guidance perpendicular hit are taken into account, so that the target′s relative bearing angle can facilitate the recognition and the hit. Simulation results show that the variation of target′s relative bearing angle obtained by the proposed method facilitates both the target recognition and the perpendicular target hit.
