| 摘 要： | 利用多波束反向散射数据进行海底底质分类是目前多波束声纳系统应用的一个热点研究方向.然而,由于海底不规则地形的影响,多波束声纳接收的反向散射信号,往往不能够真实表达海底底质的性质.因此,消除地形对多波束反向散射数据的影响是提高海底底质分类精度的一个重要步骤.本文基于多波束系统的特点,在详尽分析了地形对多波束反响散射数据影...

| Abstract: | 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 do not 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 method of multibeam backscatter data was pr... |
