Abstract

The present disclosure provides a LADCP-USBL combined observation and data processing method and an apparatus. According to one embodiment, an exemplary method may include: acquiring bottom tracking data from the LADCP, position trajectory data collected by the USBL, and ocean current data collected by the LADCP; removing abnormal data points from the position trajectory data; performing azimuth angle correction on the position trajectory data according to the bottom tracking data to determine a movement velocity of the LADCP; and calculating an absolute ocean current velocity according to the movement velocity of the LADCP and the ocean current data.
