With the modern ship radiation noise spectrum significantly reduced, the intensity of the underwater acoustic signal received by the passive sonar is correspondingly reduced. In the case of distant sea, the actual received signal to noise ratio is very low. The conventional linear detection method can achieve good detection effect under the condition of high signal-to-noise ratio. However, when the signal-to-noise ratio is very low, the target signal is almost completely submerged by strong noise, and the detection effect is extremely poor, greatly reducing the detection probability. In this paper, the bistable Stochastic Resonance of the nonlinear processing method is used to detect the underwater acoustic signal. The experimental results show that the proposed method can detect the target signal with low SNR (-20 or even-30dB) Method, which can break the shackles of very low SNR, and has a good application prospect and research value.
