摘要
本文讨论了当γ~2σ~2<1时的反向散射函数,给出修正后的表达式。以SEA BEAM多束声呐为例,说明当垂直入射时,修正项不可忽略。
Backscatttering function for γ2σ21 was discussed and modified terms were presented. We use the SEA BEAM multibcam sonar system as an example to consider the contribution of the modified terms, which is not negligible when the sonar beam is perpendicular to the sea bottom.
