摘　　要：论述了潜艇噪声水平对敌方和我方被动声呐探测距离的影响,给出了声呐工作在1 kHz时,本艇辐射噪声降低导致敌方被动声呐作用距离降低变化关系曲线,及本艇自噪声降低对我方声呐被动探测作用距离提升之间的变化关系曲线。分析结果表明,降低本艇的辐射噪声,可以降低敌方声呐的探测距离,从而增强我方潜艇的隐蔽性;当声呐平台噪声大于海洋环境噪声时,降低本艇的自噪声可提高我方潜艇被动声呐的探测距离,从而提高我方潜艇的先敌发现能力。This text dissertated the noise level of submarine bring to the influence of detection range for enemy and our passive sonar, at the same time the ralation curves of the submarine radiation noise level vs. the detection range of enemy sonar and the self-noise level vs. the detection range of self-sonar when the sonar was working on 1 kHz were proposed. The analysis results shows that the reduction of self submarine radiated noise can reduce the detection range of enemy sonar to enhance the stealthy, and that the reduction of self noise can improve the detection range of self passive sonar when self noise is great than ambient noise, so self submarine can detection before enemy.
