Abstract In this paper, using the stochastic resonance technique, the detection method of weak signal is simulated, then the increasing of SNR and the detecting of weak signal are investigated. And the signal passing through the stochastic resonator is compared with the original signal. It indicates that the stochastic resonance is fully able to become a strong newtool in signal detection.
