摘要：
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. (c) 2007 Elsevier Ltd. All rights reserved.
