Surface sensing method

Abstract

In recent years there has been a growing need for the ability to measure ocean waves in the limited area of water from a moving vessel or ashore when special survey conditions are needed. For these problems a new grazing laser remote sensing method has been designed at the P.P. Shirshov Institute of Oceanology. It is based on the pulse laser range finder method and light volume dissipation in the water. The method allows the determination of significant wave height estimates and spectral maximum frequencies. The system senses the level of the sea surface by sending short laser pulses to the sea. The back scattered pulse is detected by the optical receiver due to the light volume dissipation in the sea surface water layer. The simple reconstructed system optimises an informational capability of lidar remote technology and could be used for multipurpose open sea oceanological applications.<>
