水下爆炸对抗鱼雷声纳效能分析

Utility Analysis of Underwater Explosion Against Torpedo Sonar

水声对抗中由于战术使用及作战态势的复杂性,使得水下连续爆炸对抗鱼雷声纳的效果难以评估。本文分析了水下连续爆炸对抗鱼雷声纳的原理及其对抗主动、被动声纳的模型,针对有无水下爆炸干扰的2种情况,建立了主动声纳探测模型,并且根据模型求解了在不同频率、不同装药量下主动声纳的探测距离,然后以探测距离平均缩减量及平均缩减率为准则,运用仿真判断对抗效果,分析了有无水下爆炸声干扰时主动声纳探测距离随频率、装药量的变化规律。

It is difficult to evaluate the effect of underwater continuous explosion countermeasure against torpedo sonar due to the complexity of tactical application and operational situation in acoustic countermeasure. This paper analyzes the principle of underwater continuous explosion countermeasure against torpedo sonar and the countermeasure models of active and passive sonar. Active sonar detection models are established with and without underwater explosion interference, the active sonar detection distances are solved with these models in the conditions of different frequencies and charges. And the average reduction amount and reduction rate of the detection distances are used to judge the counter- measure utility via simulation, and to analyze the variations of active sonar detection distance versus frequency and charge with and without underwater explosion interference.
