Evaluation of the method based on PSR techniques for target detection in reverberation

In this paper, we consider the problem of target detection in the presence of sea-bottom reverberation. The method based on parameter-induced stochastic resonance (PSR) is adopted, and the non-Rayleigh properties of reverberation, as well as some random characteristics of target echoes, such as random phase and amplitude, are involved. Numerical simulations are carried out to evaluate the performances of the method based on PSR techniques versus the conventional method. The results show that when the number of scatterers that contribute to the reverberation at the same time becomes smaller, the receiver based on PSR techniques will perform better and be more efficient for reverberation suppression than the conventional receiver.
