Abstract

The deep-towed sub-bottom profiling method is widely used in deep-sea engineering geological surveys due to its high resolution and low noise characteristics. However, due to the cable-towing operation method, the collected profile data cannot reflect the actual geological conditions, and post-processing is required to correct the false fluctuations in the strata. The surge correction methods commonly used for shipborne sub-bottom data are ineffective for correcting false fluctuations caused by cable-towing operations. This paper analyzes the feasibility of correcting false fluctuations based on bathymetric data, starting from the working characteristics of deep-towed multi-sensor integrated detection and the measurement principles of sub-bottom profiling. The effectiveness of the correction method based on multi-beam bathymetric constraints is verified through actual data.
