北极喀拉海三种典型动力现象的SAR遥感观测

Observation of SAR remote sensing images of three typical dynamic phenomena in the Arctic Kara Sea

摘要:

利用Sentinel-1遥感图像对北极地区喀拉海的三种典型动力现象进行了遥感观测,在喀拉海的SAR图像中发现了清晰的海洋内波、涡旋和锋面的表面特征。根据喀拉海的地形和水动力结构对喀拉海海洋现象的SAR图像进行了解译,为高纬度地区SAR图像特征识别与分析提供了参考,有助于深入开展星载SAR北极地区海洋现象的遥感研究。

Abstract:

Three typical dynamic phenomena in the Kara Sea in the Arctic region were observed using Sentinel-1 images. Clear surface features such as ocean internal waves, eddies, and fronts were found in the SAR images of the Kara Sea. Based on the terrain and hydrodynamic structure of the Kara Sea, the SAR images of the ocean phenomena in Kara Sea are interpreted, providing a reference for the recognition and analysis of SAR image features in high-latitude areas, and contributing to the in-depth remote sensing research of spaceborne SAR ocean phenomena in the Arctic region.
