当前，各海军大国都在潜艇的设计和改造中努力减小其声频信号，即降低自噪声与辐射噪声和减小目标强度，用于提高自身的隐蔽性能，减小被非合作方探测到的可能性。本文对今后15年国外潜艇声频信号特征控制的发展进行了概述。 At present, all naval powers have made efforts to reduce their audio signals in the design and reconstruction of submarines, that is, to reduce self-noise and radiation noise and to reduce target intensity, so as to improve their concealment performance and reduce detection of non-cooperative parties possibility. This article gives an overview of the development of feature control of foreign submarine audio signals in the next 15 years.
