用微波遥感技术对海底输油管道进行监测

对假定海底管道发生油溢事故时形成的空气、油膜和海水的组合体模型进行了详细分析,揭示了模型的辐射亮温与油膜厚度的关系、有效发射率增量与入射角之间的关系、不同频率下辐射亮温与油膜厚度之间的关系。得出,利用微波遥感技术检测海底管道泄漏及泄漏量、污染区域在理论上是可行的,并由此理论设计了机载微波辐射计,文章还介绍了该系统的组成结构和系统的优选方案,指出利用高精度微波辐射计架设在无人机上监测的优点。

Monitoring Submarine Pipeline Using Microwave Remote Sensing Technology

This paper analyzes the synthetic model concerning air, oil film and sea water in an assumed submarine pipeline oil spill accident; reveals the relation between radiation brightness temperature and oil film thickness at different temperatures as well as the relation between effective emissivity and incident angle. It is shown that the submarine pipeline leakage detection using microwave remote sensing technology is theoretically feasible, and an airborne microwave radiometer is designed based on this theory. The paper introduces the configuration and optimum scheme of this system; indicates the merit of using the high precision microwave radiometer in unmanned airplane for submarine pipeline monitoring.
