声纳丢失目标时线导鱼雷的导引方法

WIRED TORPEDO GUIDANCE WHEN SONAR LOSES CONTACT WITH TARGETS

声纳在跟踪目标时失去对目标的接触是一种并不罕见的现象，在线导鱼雷导引过程中尤其是如此，因为鱼雷本身的辐射噪声就是声纳工作的一个干扰源．针对这一实际问题研究了一种鱼雷导引方法，并对这种方法进行了理论分析和仿真验证．结果表明，这种方法导引效果良好，具有很好的应用前景．

It is not unusual that sonar loses contact with targets while tracking them, especially when it is used to guide wired torpedoes simultaneously, for the radiation noise from the torpedoes is an interference to its operation. A torpedo guidance approach on such condition is developed in this paper. Results concluded from both theoretical analysis and digital simulations show that the approach is effective and exhibits great application potential.
