| The continuous walk-behind single-channel seismic system, with its technical advantages of high precision and high resolution, is gradually becoming an important tool for judging the distribution characteristics of subsea strata and determining the spatial morphology of geological structures. However, this technology brings problems such as strong reflections from the seafloor producing multiples, uneven distribution of trace energy, and large differences in vertical amplitude energy due to its non-uniform sampling mode and low coverage rate. To solve these problems, this paper proposes a data processing method: low-cut filtering can be used to filter out high-frequency noise and improve the clarity of the signal; random noise suppression technology can effectively suppress spatial random interference and improve the reliability of the signal; multiple wave suppression technology can reduce the interference of multiple waves and improve the quality of the seismic section; amplitude compensation technology can also be used to enhance effective signals and improve the resolution of the seismic section. After processing actual data, the signal-to-noise ratio and resolution of the section will be significantly improved, and the geological information of the seafloor will be revealed more accurately. |
