摘　　要：为了高可靠性地提取星载云/气溶胶激光雷达层次信息,设计了一种基于直方图统计的层次分类方法。对这种方法进行了理论分析。结果表明,该方法应用于不同特征的数据,均能准确、高可靠性地查找出云/气溶胶的层次信息。该方法避免了目前层次查找方法对数据特征的约束,是一种高可靠性、适用范围广的层次查找算法。In order to extract the layer for space-borne cloud / aerosol lidar reliably,a layer classification method based on histogram statistics was proposed. This method was analyzed theoretically. The experimental results show that the cloud / aerosol layer can be extracted reliably in different situations with this method. Compared with the current layer detection method,the new method can avoid the constraint for data feature. It is a highly-reliable and widely-applicable layer detection method.
