| 摘 要： | 本文在探讨多波束反向散射强度与海底底质类型关系的基础上,主要针对目前广泛使用的Simrad EM系列多波束,详细描述了在数据获取期间系统进行的实时补偿,分析了反向散射强度数据中残留的入射角和波束模式指向性等因素的影响,给出了相应的改正方法。计算结果表明,本文给出的方法可对反向散射强度数据进行有效的处理,为正确使用声纳图像进行海底底质的判读提供了保证。

| Abstract: | On the basis of the relationship between multibeam backscatter and seatloor characterization,this paper focused on the widely-used Simrad EM muhibeam,elaborated real time corrections during data acquisition,analyzed the influence of incidence and beam pattern remaining in backscatter,and presented correcting methods.Practical computations showed that the method could effectively process the backscatter and insure legitimate seafloor classification by using sonar images. |
