多波束声纳图像整体灰度不均匀及中央波束区反射异常校正方法
The Correction Method of Intensity Distortions and Backscattering Exquisite Data from Multi-beam
摘要
Abstract
Since the intensity distortions and there are some abnormal backscattering da- ta of multi-beam sonar image, the data before bottom classfying must be correct. The reasons that leading to intensity distortions and the main factors producing the exquisite backscatter- ing data near nadir are discussed in this paper. The intensity distoritions is corrected, and so is the abnormal data according to analyzing the principle of multi-beam system.关键词
