As an active remote sensing technology, airborne LIDAR can work at all times while emitting specific wavelengths of laser light that penetrate seawater. Airborne bathymetry (ALB) records object’s full return waveform, including the water surface, column, seafloor, and objects on it. Due to seawater’s absorption scattering seafloor’s reflectivity effect, amplitude seafloor echoes varies greatly....
