摘　　要：给出了单波束测深的原理,分析了单波束观测数据预处理模型,提出了采用单波束测深成果检核机载激光数据质量的技术方法,并以我国自行研制的机载激光测深系统为例,给出了该系统在某海区试验数据的外部检核结果。针对两种测深手段之间明显存在系统性偏差的问题,提出了以单波束测深成果为控制,对机载激光测深数据系统偏差进行校正和补偿的处理方案。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.
