摘要
简述回声仪定标延时的改正数的推求,并同测某一水下地形,分别采用SDH-13D、SDH-13A回声仪定标延时绘出地形图,进行改正前后等高线走势和断面数据的比较.
The calculation of the correction data of the scaling time delay of the echometer was stated. The geomorphologic map was drawn respectively by the scaling time delay of SDH-13D and SDH-13A echometer in order to measure a underwater geomorphy. And the comparison of the contour trend and the cross section data before and after the correction was made.
