一种多波束反向散射数据的地形校正算法

Bottom sediment classification with multibeam backscatter data is a research hotspot of application of multibeam system. However, the backscatter data received by multibeam system sometimes don’t indicate the real characters of bottom sediment because of the influences of complex terrain. Therefore, removal of topographic effects on multibeam backscatter data is an important pretreatment to improve the accuracy of classification. In this paper, a topographic correction of multibeam backscatter data has been proposed, and the method yielded a satisfied result.
