Abstract

A theory for electromagnetic scattering from a slightly rough surface is developed that is based on application of an effective boundary condition. The theory generalizes previous approaches that apply only to the infinite dielectric constant (/spl epsi//spl rarr//spl infin/) limit to cases of finite but large /spl epsi/. Also, the theory yields the known results by J. Wright. In a particularly important case of scattering from the ocean, the backscatter cross-section is dramatically different from that calculated for /spl epsi//spl rarr//spl infin/ over a wide range of incident angles, for both vertical and horizontal polarization.

具有有限大介电常数的介质表面稍微粗糙的微波散射，并应用于空气-水散射

提出了一种基于有效边界条件应用的微粗糙表面电磁散射理论。该理论将以往只适用于无限介电常数(/spl epsi//spl rarr//spl infin/)极限的方法推广到有限但较大的/spl epsi/情况。此外，该理论还得出了赖特(J. Wright)的已知结果。在一个特别重要的来自海洋的散射情况下，在很宽的入射角范围内，垂直和水平极化的后向散射截面与/spl epsi//spl rarr//spl infin/计算的后向散射截面有很大的不同。

期刊介绍： Remote Sensing Information is a bimonthly academic journal supervised by the Ministry of Natural Resources of the People's Republic of China and sponsored by China Academy of Surveying and Mapping Science. Since its inception in 1986, it has been one of the authoritative journals in the field of remote sensing in China.In 2014, it was recognised as one of the first batch of national academic journals, and was awarded the honours of Core Journals of China Science Citation Database, Chinese Core Journals, and Core Journals of Science and Technology of China. The journal won the Excellence Award (First Prize) of the National Excellent Surveying, Mapping and Geographic Information Journal Award in 2011 and 2017 respectively. Remote Sensing Information is dedicated to reporting the cutting-edge theoretical and applied results of remote sensing science and technology, promoting academic exchanges at home and abroad, and promoting the application of remote sensing science and technology and industrial development. The journal adheres to the principles of openness, fairness and professionalism, abides by the anonymous review system of peer experts, and has good social credibility. The main columns include Review, Theoretical Research, Innovative Applications, Special Reports, International News, Famous Experts' Forum, Geographic National Condition Monitoring, etc., covering various fields such as surveying and mapping, forestry, agriculture, geology, meteorology, ocean, environment, national defence and so on. Remote Sensing Information aims to provide a high-level academic exchange platform for experts and scholars in the field of remote sensing at home and abroad, to enhance academic influence, and to play a role in promoting and supporting the protection of natural resources, green technology innovation, and the construction of ecological civilisation.
