摘要

分析了法国CNES公司研制的机载POLDER模拟器观测到的海岸带极化现象。结果表明，在波长/spl λ /=850 nm处，海岸带的极化度小于距离陆地较远的海面，而在波长/spl λ /=450 nm处，海岸带的极化度与距离陆地较远的海面的极化度基本相同。本研究利用单一散射辐射传输模型，评估了邻接效应对偏振测量的影响。结果发现，在/spl λ /=850 nm处，由于陆地表面反射的辐射产生的相邻效应更加显著，海面上的极化程度变小。

Estimation of adjacent effects in polarization measurements over the coastal zone

The polarization over the coastal zone observed by the airborne POLDER simulator, which was developed by CNES, France, is analyzed. It is shown that at the wavelength /spl lambda/=850 nm, the polarization degrees over the coastal zone become smaller than those over the sea surface at a long distance from the land, while at /spl lambda/=450 nm the polarization pattern over the coastal zone is almost the same as that over the sea surface distant from the land. In this study, the adjacency effect influence on polarization measurements is evaluated by using a single scattering radiative transfer model. As a result, it is found that at /spl lambda/=850 nm, as adjacent effects arising from the radiation reflected by the land surface are more significant, the degree of polarization over the sea surface becomes smaller.

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.
