摘要
海冰是全球变化的指示剂,海冰厚度是海冰最难探测的参数之一。文章对现有的海冰厚度探测方式以及近年来相关研究进行了全面回顾和分析,对卫星雷达高度计、合成孔径雷达反演冰厚所存在的问题进行了总结;重点分析了星下点观测模式的雷达高度计以及雷达干涉测量技术在海冰厚度探测中的应用,分析了三维成像雷达成像高度计在海冰探测中的潜力,以及三维成像雷达成像高度计在海冰厚度探测机理及数据处理方面存在的问题。
Sea ice is an indicator of global change,and sea ice thickness is one of the most difficult parameters to detect.In terms of the existing methods as well as the related research of sea ice thickness detection in recent years,a comprehensive review and analysis is carried out in this paper.The problems existing in sea ice thickness inversion by spaceborne radar altimeter and synthetic aperture radar are summarized.It focuses on analyzing the application of radar altimeter and radar interferometry in sea ice thickness detection based on the nadir observation mode.It also analyzes the application potential and the problems of mechanism and data processing in detecting the sea ice thickness using three-dimensional imaging altimeter.
