Research on submarine-launched wire-guided torpedo wake-to-acoustic guidance method based on Target Indication Information

针对目指信息保障下潜射线导鱼雷远距离攻击时,采用线导+尾流自导鱼雷捕获目标概率较低的问题,提出当鱼雷越过目标推算航向线后将尾流自导转换为声自导的制导方式。介绍目指信息传输模型、目标运动假设模型、鱼雷曲线转向模型和线导+尾流自导推算前置点导引模型;提出一种鱼雷尾转声制导方式,分析目标推算航向线、尾转声时机、尾转声鱼雷航向和鱼雷到达目标散布中心后的机动搜索方案。通过仿真计算,分析了线导+尾流自导、线导+声自导和线导+尾转声等3种制导方式在不同初始态势下的鱼雷捕获概率,验证了采用尾转声制导方式兼具尾流自导鱼雷抗干扰能力强和声自导鱼雷捕获概率高的特点。

In order to solve the problem of low probability of target capture by wire-guided+wake homing torpedo under the support of target indication.The guidance method of converting wake homing to acoustic homing is put forward when torpedo passes over the calculated target course line.Firstly,the target indication information transmission model,the target motion hypothesis model,the torpedo curve steering model and the wire-guided+wake homing calculated pre-point guidance model are established.Secondly,a torpedo wake-to-acoustic guidance method is proposed,and the calculated target course line,the wake-to-acoustic time,the wake-to-acoustic torpedo course and the maneuvering search scheme after torpedo reaching the target dispersion center are analyzed.Finally,through simulation calculation,the torpedo capture probabilities of wire-guided+wake homing,wire-guided+acoustic homing and wire-guided+wake-to-acoustic guidance under different initial conditions are analyzed,and it is verified that the wake-to-acoustic guidance method has the characteristics of strong anti-interference ability of wake homing torpedo and high acquisition probability of acoustic homing torpedo.
