Abstract

PURPOSE:To enable to perform accurate mine sweep measurement, by measuring the depth of measured sea bottom as the difference with the reference surface on the reference block installed in the sea. CONSTITUTION:The ultrasonic wave signal transmitted from each transceiver 11 of the transceiver array 1 is reflected on the measured sea bottom 6 of reference surface 71 of the reference block 7 and returns to the transceiver 11 of the transceiver array 1. This reflection signal is received at each transceiver 11 and is fed to the transceiver 2 and further fed to the control processing unit 5 via the depth processing unit 3. The CRT display 4 displays the sea bottom section shape, depth distribution diagram and desired diagram.
