摘要
Abstract
Based on the time-domain characteristics of ocean LiDAR bathymetry echoes,the dif-ferent characteristics of seawater body scattering and seafloor echoes,as well as the noise statisti-cal characteristics of different echo data in different fields of view are analyzed.An ocean bathy-metry echo classification method based on the echo time-domain characteristics and dual-field fu-sion for spaceborne LiDAR is proposed.Airborne test data around some island and reef areas shows that the classification method proposed can achieve a classification accuracy of 9 9.4%,and the method is relatively simple and easy to implement,and the method can provide effective tech-nical support for the development and application of spaceborne ocean detection LiDAR.关键词
