激光雷达对沉潜油探测的探索*

Exploration of submerged oil detection by Lidar

摘要:

目前，人们对于海洋沉潜油的规律研究及控制水平较低，特别是探测 30m 深度以内的浅海地区的沉潜油分布信息，其主要原因是缺乏快速有效的探测手段。北京遥测技术研究所开发水下探测激光雷达样机，利用激光在海水中良好的透过特性，用于对水下沉潜油的探测以及对海底等目标的高精度探测。样机完成在水池中进行水下沉潜油的模拟探测试验，对沉潜油样本的典型激光回波信号进行采集分析，并测量模拟探测深度。试验结果基本符合设计预期， 为进一步提升激光雷达沉潜油探测能力打下良好基础。

Abstract:

At present, the level of ocean submerged oil research and control is still low, especially for detecting the distribution information of submerged oil within 30m, the main reason is the lack of fast and effective detection methods. The Beijing Research Institute of Telemetry developes a prototype of underwater detecting lidar, by using the good transmission characteristics of laser in seawater, it can be used for submerged oil detection, and for high-precision detection of other objects like seabed. The prototype carried out the simulated detection test of the submerged oil in the pool, collected and analyzed the typical laser echo signals of the samples, and measured depth. The results are basically in line with the designed expectations, which lays a good foundation for further improving the submerged oil detection capability of lidar.
