摘要
本文详细论述机载激光海洋测深的基本原理；讨论机载蓝绿激光的最大探测深度及测深精度等关键指标；对高频率短冲脉激光器及大动态范围的微弱信号检测等关键技术也进行了论述；并简要介绍该技术的国内外发展动态，最后分析机载激光海洋测深技术在我国的现实需要及可行性。
The optical nature of ocean water is of great importance to the airborne laser depth sounding. The scattering and absorption of laser in the sea result in the difficulty of the signal detecting. They can also result in a delayed laser pulse on reflection from the sea bottom into the airborne receiver system. This paper describes the passage characteristic of laser transmission in the sea in detail from analyzing the absorption and scattering of the ocean water.
