UNDERWATER DETECTION DEVICE AND UNDERWATER DETECTION METHOD

摘要

The present invention relates to an underwater detection device and an underwater detection method and, more particularly, to an underwater detection device comprising two DC electrodes and multiple measurement electrodes in order to sense an underwater movement of an object, which has an electric conductivity different from that of water. The present invention comprises two DC electrodes, multiple measurement electrodes, and a control/measurement module for measuring voltages of the multiple measurement electrodes, thereby being able to accurately detect the presence of a moving object even in an area with severe noise due to strong tides or in an area where water layers with temperature and salinity differences are mixed.
