摘要
简述了由多波束原始声强数据生成的声纳图在海底底质分类方面的应用中存在的问题,根据同一海底底质的海区对声波的平均反向散射强度随地形成连续变化的规律,提出了差值补偿法,解决了声纳图中由于地形变化所产生的声强信息的损失;在此基础上,根据Lambert法消除了海底地形起伏对声纳图的影响,从而得到只反映海底底质特性的海底声强图。
This paper simply describes the problems of the application in bottom characteristics sorting with the sonar image created by multibeam sound intensity data. A distortion compensation method is proposed according to the rule that average reverse dispersion intensity is changing continuously at sea with same bottom characteristics, and sound intensity loss in sonar image caused by terrain changing is solved. Besides, the effect caused by sea terrain changing is removed according to the Lambert principle, and sound intensity image reflecting bottom characteristics particularly is got.
