在当前以水声为主要探测手段的情况下,影响核潜艇隐蔽性的最主要因素是核潜艇本身的噪声水平。核潜艇的噪声一般分为辐射噪声和自噪声。前者是噪声源的外场效应,是敌方被动声纳探测核潜艇方位和水中兵器跟踪起爆的信号源;后者是噪声源的一种内部效应,是本艇水声器材的主要干扰源,对本艇声纳的正常工作和探测距离有很大的影响,并影响艇内工作环境,不利艇员的身心健康。因此,多年来世界各海军大国都不遗余力地进行核潜艇噪声的综合治理工作,力求在核潜艇的安静化方面取得突破性的进展。目前在这方面处于领先地位的美国,已经把弹道导弹核潜艇的噪声源级从1960年“乔治·华盛顿”级(GeorgeWashington)的156分贝降到“俄亥俄”
In the current case of underwater acoustic detection, the main factor that affects the covert submarine submarine is the noise level of the nuclear submarine itself. Nuclear submarine noise is generally divided into radiation noise and self noise. The former is the noise field of the external field effect is the enemy passive sonar detection of nuclear submarines and water weapons tracking the initiation of the signal source; the latter is an internal source of noise, is the main source of underwater acoustic equipment, the ship Sonar’s normal work and detection range have a great impact, and affect the working environment inside the boat, detrimental to the physical and mental health of the crew. Therefore, all naval powers in the world have spared no efforts in the comprehensive management of nuclear submarine noise over the years and made every effort to make breakthrough progress in the quieter submarine. The United States, which is currently the leader in this regard, has reduced the noise level of ballistic missile submarines from 156 dB at George Washington grade in 1960 to “Ohio”
