Abstract

In this letter, an appropriate approach is proposed for modeling the electromagnetic (EM) scattering from composite rough surfaces made up of wake due to a submerged body and wind-driven sea waves. The computational fluid dynamics (CFD) method is used to extract the air–seawater surface wake generated by an underwater moving body at different speeds and depths. Then, the wake is superimposed on the randomly rough wind-driven sea surfaces that obey the Pierson–Moskowitz power spectrum. The small slope approximation (SSA) method is adopted to calculate the EM scattering by the composite surfaces. The simulation results are obtained and justified.

淹没体尾流和风驱动海浪复合表面的电磁散射建模

在这封信中，提出了一种适当的方法来模拟由淹没体和风力驱动的海浪引起的尾流组成的复合粗糙表面的电磁散射。计算流体动力学（CFD）方法用于提取水下运动体在不同速度和深度下产生的空气-海水表面尾流。然后，尾流叠加在随机粗糙的风驱动海面上，这些海面遵循皮尔森-莫斯科维茨功率谱。采用小斜率近似（SSA）方法计算复合材料表面的电磁散射。仿真结果得到了验证。

期刊介绍： IEEE Geoscience and Remote Sensing Letters (GRSL) is a monthly publication for short papers (maximum length 5 pages) addressing new ideas and formative concepts in remote sensing as well as important new and timely results and concepts. Papers should relate to the theory, concepts and techniques of science and engineering as applied to sensing the earth, oceans, atmosphere, and space, and the processing, interpretation, and dissemination of this information. The technical content of papers must be both new and significant. Experimental data must be complete and include sufficient description of experimental apparatus, methods, and relevant experimental conditions. GRSL encourages the incorporation of "extended objects" or "multimedia" such as animations to enhance the shorter papers.
