ABSTRACT:
A method of remote sensing of water surfaces using laser beams of slightly differing frequencies. Laser radiation scattered from the water surface is collected and processed to determine the surface gravity wave and capillary wave spectrum and surface currents. Maps may be constructed using either land-based or airborne .increment.k-lidar stations.
