Abstract

A method based on parameter-induced stochastic resonance is proposed for target echo detection in the presence of shallow-water reverberation. The signal received by the horizontal sensor array is normalized and delayed to form the input to a bistable system. The system parameters are tuned properly to maximize the detection performance based on parameter-induced stochastic resonance techniques. Considering the limitation on the length of receiving arrays, the space-time unfolding method is suggested to largely improve the detection performance.
