在海底回波信号处理中，根据接收噪声的垂直相干性，将接收到的总噪声近似为洛伦兹形式。然后提出了一种基于参数诱导随机共振(PSR)的方法。数值仿真结果表明，通过调整系统参数，PSR方法可以有效地恢复受高斯噪声干扰的空间信号。在处理受K分布包络噪声干扰的空间信号时，PSR方法具有很好的适用性。
In the processing of sea-bottom echo signal, the total received noise is approximated to Lorentzian form according to its vertical coherence. Then a method based on parameter-induced stochastic resonance (PSR) is presented. By means of tuning system parameters, numerical simulation shows that PSR method can effectively recover the spatial signal interfered by Gaussian noise. It also shows that PSR method has well applicability when processing spatial signal interfered by K-distributed envelope noise.
