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响的基础上,提出了一种多波束反向散射数据的地形校正算法。试验表明,该方法能够快速有效地消除地形对反向散射数据的影响,恢复海底底质的真实信息。 Bottom sediment classification with multibeam backseatter data is a research hotspot of application of muhibeam system. However, the backscatter data received by muhibeam 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 baekscatter data was proposed, and the method yielded a satisfied result.
