一、海洋混响统计特性研究的主要结果1.四十年代,主动声响在了解水下状况中开始起重要作用,接收有用信号时,同时也收到所谓发射信号的余振,它是与声波在水介质中的各种非均匀性和各个边界上的散射有关的。水介质对发射信号的这种“响应”叫做海洋混响。不久就注意到海洋混响是随机性的,并开始用统计方法来表示它。 First, the main results of the study on the statistical characteristics of ocean reverberation 1. In the 1940s, the active sound began to play an important role in understanding underwater conditions. When receiving useful signals, it also received the so-called emission signal of the residual vibration, it is with the sound waves Various inhomogeneities in aqueous media are related to scattering at various boundaries. This ’response’ of an aqueous medium to a transmitted signal is called ocean reverberation. It soon became apparent that the ocean reverb was random and began to express it statistically.
