N2 - In this paper, the second-order stochastic resonance (SR) system with Levy noise is analyzed, and the improved numerical method is proposed to obtain the output signal sequence after the SR system. Then the matched stochastic resonance (MSR) system is investigated and derived to produce a stable SR phenomenon in Levy noise circumstance. The matched performance is then evaluated which reflected the efficiency for arbitrary frequencies. And it seems achieve a better enhancing performance in the very low frequency band (0.01-100Hz), which is considered as the ship seismic signal. Moreover, the simulation results of the frequency detection verify the effectiveness of the MSR system. It is extremely helpful to detect the underwater very low frequency (VLF) weak signal under the strong background noise of the complex marine environment.
