声自导鱼雷搜索航路威胁区域分析

Analysis of Acoustic Homing Torpedo Searching Threat Area

针对水面舰艇遭受声自导鱼雷攻击无法确定鱼雷航向问题,给出了声自导鱼雷搜索航路威胁区的定义,提出了威胁航向范围求解的迭代法和估算法。该方法从水面舰艇防御的角度出发,在概略估计鱼雷位置及航速情况下,直观地给出声自导鱼雷有效攻击航向范围,从而确定鱼雷的威胁区,为水面舰艇鱼雷防御决策提供理论依据。相比于以往仅凭经验判断来袭鱼雷信息,论文方法可有效地缩小来袭鱼雷威胁区范围,在舰艇火控系统中嵌入该算法可以实时判断并显示来袭鱼雷的威胁区,从而提高水面舰艇水下拦截的效率。

Against the background of acoustic homing torpedo attacks on surface ships,this study presents a definition of an acoustic homing torpedo searching the threat area,and then solves the threat range using an iteration method and an estimated method.From the perspective of surface ship defense,in the brief estimation of torpedo position and speed,the intuitively gives acoustic homing torpedo effective attack course range,to determine the threat area of torpedo,and provides a theoretical basis for torpedo defense decisions of surface ships.Compared to the experience estimate,the method in this study can effectively reduce the scope of the torpedo threat area,and embedding the algorithm in the ship fire control system can judge and display the threat area of the incoming torpedo in real time,increasing the efficiency of the surface ship undersea interception.
