Stochastic resonance proposed a new non-linear weak signal detection method in recent years, which can be used to enhance the useful signal by using noise, to achieve the purpose of detecting weak signals. This article focuses on the theory of stochastic resonance under strong noise background of non-periodic signal detection methods. This research is subsidized by the project“Research on nonlinear filter theory and technology based on Stochastic Resonance theory”, which is supported by National Natural Sci...
