Overview of ocean bathymetric LiDAR

Abstract

Ocean bathymetric LiDAR relies on high efficiency, high precision, fast, safe, etc. characteristics, can used to conveniently acquire underwater terrain data, ocean surface laser scattering, near-coastal engineering, and detection of underwater mines and other targets. So, the United States, Canada, Australia, etc., have competed to develop ocean bathymetric LiDAR. Laser energy, laser repetition frequency, max sounding depth, min sounding depth, point cloud density and vertical accuracy have been greatly improved. Because the problems of large size, heavy weight, and the need to carry manned aircraft platforms and airport runways of this LiDAR, the United States, Austria and China have begun to study single-frequency LiDAR that are small in size, light in weight, capable of carrying UAV platforms, and take off anytime, anywhere.
