The thickness of Cobalt-rich Manganese Crusts (CRC) is one of the important information to map and estimate the volumetric distribution of deep-sea mineral. In this paper, we propose an improved method for measuring the thickness of Cobalt-rich Manganese Crust based on the neighborhood information and dual-channel information. The high-frequency signal and low-frequency parametric signal is obtained by feeding the signal received by the transducer centered at the array to two designed filters. The reflection instant of the top surface is determined by the high-frequency signal, while that of the bottom surface is determined by rule based on the neighborhood information assuming that the CRC has the local thickness invariability. Finally, the demonstration experiment is conducted in the tank to validate the effectiveness of the method.
