Abstract:The principle of single beam bathymetry was presented in this paper,and the preprocessing models of single beam bathymetry were analyzed.The back-check technique of airborne laser bathymetry data quality using single beam bathymetric data was proposed,which was implemented on the airborne laser bathymetry system developed in China.The results for the exterior check of the system were presented from experiments at sea.To overcome the prominent systematic bias between the two bathymetric techniques,a new processing scheme was proposed to correct and compensate the systematic bias of airborne laser bathymetry data with single beam bathymetric data as control.
Keywords:single beam bathymetry  airborne laser bathymetry  exterior check  systematic bias
