摘　　要：针对鱼雷航行姿态变化引起的声引信测距干扰问题,从三波束声引信和干扰产生的基本原理出发,采用欧拉旋转定理对波束向量进行空间变换,分析了存在航行姿态变化时的声引信各波束测距误差;在获取航行姿态数据的基础上,将航行姿态数据引入到干扰存在条件下的引信测距算法,推导了消除鱼雷航行姿态变化引起的声引信测距干扰方法。仿真试验表明,该方法可有效抑制鱼雷航行姿态变化引起的声引信测距干扰。In terms of ranging interference of an acoustic fuze due to torpedo navigation attitude changing,based on the basic principles of three-beam acoustic fuzes and interference generation,this paper applies Euler rotation theorem to spatial transformation of the beam vector and analyzes the ranging error of each beam with torpedo navigation attitude changing.Based on the acquisition of the navigation attitude data,a method is proposed to eliminate the ranging error of the acoustic fuze caused by the variation in the torpedo navigation attitude.These data are introduced into a fuze-ranging algorithm considering interference.A simulation test shows that the proposed method can effectively suppress the interference caused by the change in the torpedo navigation attitude.
