depth sounding

基本解释

The optical nature of ocean water is of great importance to the airborne laser depth sounding.
本文详细论述机载激光海洋测深的基本原理；
The return signals from airborne laser depth sounding have dynamic ranges that exceed the capabilities of the sequential measurement equipments.
对机载激光探测海水深度的大动态范围信号，提出了使用光电倍增管变增益探测方法来压缩其动态范围。
In the working of transient electromagnetic depth sounding, making single absolute positioning by the pocket GPS to measure three-dimensional coordinates can reduce amount of work and cost.
在瞬变电磁测深测地工作中，用手持式GPS单点绝对定位测定测点三维坐标，减少了控制测量环节，节约了成本。
