Research on high frequency sub-bottom profiler experimental results

In the first half of 2018, the high-frequency sub-bottom profiler completed a series of engineering prototype test and verification. Among them, in the April 6, 2018 to April 12, the device for the first time in Hangzhou thousand island lake area lake water work, on May 24, 2018-2018 on May 31, the device has been conducted on the golden pond in Ningbo offshore sea trial test, in the meantime, the device has the quietness of the abundant successful test area on the river in the park. These tests are the preliminary inspection of the self-developed deep-sea manganese nodules detection device and also the process of promoting the continuous improvement of the test device. During the experiment, we obtained broadband measured data under different experimental conditions on the frequency band of 110KHz for the first time through this series of experiments, which will facilitate us to conduct more in-depth mining and analysis of these hydroacoustic data.
