depth sounding

基本解釋

The optical nature of ocean water is of great importance to the airborne laser depth sounding.
本文詳細(xì)論述機(jī)載激光海洋測深的基本原理；
The return signals from airborne laser depth sounding have dynamic ranges that exceed the capabilities of the sequential measurement equipments.
對機(jī)載激光探測海水深度的大動態(tài)範(fàn)圍信號，提出了使用光電倍增琯變增益探測方法來壓縮其動態(tài)範(fàn)圍。
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.
在瞬變電磁測深測地工作中，用手持式GPS單點(diǎn)絕對定位測定測點(diǎn)三維坐標(biāo)，減少了控制測量環(huán)節(jié)，節(jié)約了成本。
