Abstract

The present invention relates to a polar sea ice type remote sensing monitoring method for extracting high-resolution sea ice type from passive microwave remote sensing images of the Arctic by using asuper-division technique, in particular to a high-resolution sea ice type extracting method based on the super-division technique. The invention is characterized in that the passive microwave image is firstly superdivided and reconstructed, and then the sea ice type is extracted based on the obtained high-resolution superdivided image. The invention utilizes the strategy of super-resolution reconstruction, firstly, the passive microwave remote sensing image of the polar sea ice is super-reconstructed to obtain a higher-resolution image, and then the high-resolution extraction of the polar seaice type is further realized on the basis of the super-resolution reconstruction.

Description

technical field [0001] The invention relates to a polar sea ice type remote sensing monitoring method for super-resolution reconstruction of arctic passive microwave remote sensing images by means of super-resolution technology and high-resolution sea ice type extraction. Background technique [0002] The type of polar sea ice is one of the key parameters of cryosphere and polar environment change, and plays a pivotal role in the study of global climate change. Therefore, the accurate extraction of polar sea ice types is conducive to the accurate description and reasonable prediction of the change trend of polar sea ice, and provides reliable data for applications such as polar shipping lane design. [0003] The remote sensing data used for sea ice monitoring mainly include optical image data, passive microwave data, SAR and satellite altimetry data, etc. Among them, passive microwave data has the advantages of strong penetration ability to the surface, all-weather work, an...
