Abstract
In this paper, we propose a nonlinear weak signal processing method via adaptive stochastic resonance, aiming to enhance speedboat seismoacoustic signature under low signal-to-noise (SNR) ratio. The method is a joint tuning of calculation step and frequency of signature for optimal matched output with maximal local signal-to-noise ratio enhancement. Nonlinear filter performance analysis with computer simulations is given and an experimental verification with ocean bottom seismometer (OBS) received speedboat induced seismic wave data is further processed with the proposed method, which reflect an excellent enhancement performance.
