A pregeneration–recognition method of detecting weak seafloor echoes for full-waveform airborne LiDAR bathymetry

Full-waveform airborne LiDAR bathymetry (ALB) technology, in which the analyzed waveforms reflect the temporal positions and attribute information of targets, is effective in shallow water. However, weak seafloor echoes in full-waveform data induced by environmental and device characteristics are co...
