Example Embodiment
[0033] Implementation case:
[0034] The observation area is the sea area near the Luzon Strait, and the purpose of observation is the specific method and intensity of the Kuroshio intrusion into the South China Sea. Need to observe the temperature, salinity and velocity structure of shallow water at a distance of 400 meters. The survey vessel is equipped with a sailing ADCP, but due to objective reasons such as poor sea conditions and high cleanliness of the sea in this area, the effective observation depth does not exceed 300 meters. The ADCP observation profile of the tow body is upward, and temperature and salt sensors are installed at equal intervals on the lowered steel cables.
[0035] Synchronize the tow body ADCP and navigation ADCP observation time, and combine the navigation GPS data to obtain the towed body velocity observation value. In order to obtain the structure of temperature, salt and flow velocity in shallow water layers below 400 meters.
