Abstract: Three areas of technology are thought to be the newest technology for shallow water hydrographic surveys owing to their high speed and high resolution:airborne laser hydrography(ALH),shallow water multibeam sonars(SWMB) and digital side scan sonar.The wave correction is one of the most important depth reductions for marine environment.Based on the configuration of the first set of ALH system in China,three ways available for the wave correction are proposed,and their suitability is discussed in detail.Finally,the accuracy of the correction models is estimated in theory.
