METHOD FOR MEASURING SEA WAVES BY MEANS OF ULTRASONIC WAVES AS WELL AS SEA WAVE MEASURING SYSTEM

摘要

The ultrasound waves are transmitted from the ultrasonic transceiver 2 installed in the buoy 1 to the sea and the ultrasound waves from the three transponders 3 arranged on the seabed are received together with the time signal, , The distance between each transponder (3) and the ultrasonic transceiver (2) is detected, high-pass filter processing is performed on the distance data to extract a short-period fluctuation component, A three-dimensional linear equation which becomes equal to a formula of displacement of a coordinate axis is prepared for each sound wave repeater, and this equation is solved to obtain a wave height as a displacement in a height direction.
