潜射线导鱼雷蛇形弹道设计及仿真研究

在线导鱼雷攻击过程中，当只有目标方位信息且目标舷角很小时不利于鱼雷捕获目标，为解决该问题，阐述了蛇形弹道搜索的概念，提出了2种线导鱼雷蛇形弹道搜索使用时机。建立蛇形弹道搜索控制模型，并进行了仿真验证。研究结果表明：采用线导加尾流自导蛇形弹道搜索在只有目标方位信息且小目标舷角情况下可以有效提高鱼雷捕获目标尾流的概率，为解决进入尾流舷别不确定给攻击带来的问题，又提出了利用尾流自导加声自导攻击目标的组合使用方法，该方法可保证鱼雷命中目标概率；采用线导加声自导蛇形弹道搜索在目标方位无效情况下可以有效扩大鱼雷机动范围，捕获目标概率要高于直航搜索捕获目标概率。

Snake-like Trajectory Design and Simulation of Submarine-launched Wire-guided Torpedo

During torpedo attacking, it is against target acquisition probability under the condition that the target angle is very small and only target bearing information can be obtained. The snake-like trajectory searching concept is elaborated, and the two opportunities of using the snake-like trajectory to search a target are proposed. A snake-like trajectory searching control model is established. It was validated through simulation that the snake-like trajectory searching of wire-guided+wake homing torpedo is effective for increasing the wake acquisition probability at a very small target angle and with only target bearing information. In order to solve wake entry shipboard uncertainty problem, a method of attacking a target by wake+acoustic homing is proposed, which can ensure the probability of torpedo hiting the target. The simulated results show that the snake-like trajectory searching of wire-guided+acoustic homing torpedo is effective for enlarging the torpedo searching range without target bearing information, and the target acquisition probability is high than that through direct searching.
