摘要:

为研究溢油对海面电磁散射的影响, 作者根据海面复合微波散射模型理论和蒙特卡洛统计模型理论, 通过引入单分子油膜的黏性阻尼, 对粗糙的溢油海面进行建模, 定量分析溢油对海浪谱和海面后向散射系数值两个方面的影响。为实现基于X波段雷达海面溢油检测提供理论支撑, 有助于解决溢油检测中的虚警率高的问题。

Abstract:

In this paper, we mainly consider the effects of oil spills on sea-surface scattering, based on the theories of the composite microwave scattering and Monte Carlo statistical models. We introduce the viscous damping of single-molecule oil film, model the rough oil-spilled sea surface, and quantitatively analyze the influence of oil spill on two aspects of the ocean wave spectrum and the sea surface backscattering coefficient. Our findings provide theoretical support for the detection of spilled oil at sea level by X-band radar, which can be used to reduce the high false alarm rate in oil spill detection.

Key words: Sea-surface oil spill Monte Carlo model composite microwave scattering model
