鱼雷航速对潜艇鱼雷报警距离的影响分析

针对双速制反潜鱼雷在潜艇鱼雷报警声纳作用下的作战使用问题，由辐射噪声经验公式分析了鱼雷航速的变化对其辐射噪声强度的影响。根据被动声纳方程，在鱼雷航速变化情况下，研究了潜艇鱼雷报警声纳对双速制鱼雷报警距离的变化规律。计算结果表明，鱼雷报警距离随鱼雷航速增加而增加，提出了双速制鱼雷作战使用中应注意航速设置，以低速航行来降低潜艇的鱼雷报警距离，从而增强鱼雷的隐蔽性以及攻击的成功率，为鱼雷攻潜战术研究提供参考。

Influence of Torpedo Speed on Submarine's Torpedo Warning Distance

To study the operational application of a double-speed anti-submarine torpedo under the effect of submarine＇s torpedo warning sonar, the influences of the variations of torpedo speed on its radiation noise intensity are analyzed by using the empirical formula of radiation noise. According to the analysis of passive sonar equation, the variation rule of the warning distance of torpedo sonar is investigated for varying torpedo speed. Calculation result shows that torpedo warning distance increases with torpedo speed. It is suggested that attention be paid to presenting torpedo speed in the operational application of a double-speed torpedo to reduce the torpedo warning distance by low speed running, and to enhance stealth of the torpedo and success probability of the attack.
