Abstract:
随着遥感技术的发展,海面高度的精度和时空分辨率得到了大幅提高,为获取高精度高分辨率的海面动力高度提供了条件。本文介绍了海面动力高度反演模型,并从测量特点和反演方法等方面对成像高度计和传统的雷达高度计进行了比较,并分析了成像高度计在海面动力高度反演精度和时空分辨率上的优势。
With the development of remote sensing technology, the accuracy and spatiotemporal resolution of sea surface height have been greatly improved, which provides conditions for obtaining high-precision and high-resolution sea surface dynamic height. In this paper, the inversion model of sea surface dynamic altitude is introduced, and the imaging altimeter and the traditional radar altimeter are compared from the aspects of measurement characteristics and inversion methods, and the advantages of imaging altimeter in the inversion accuracy and spatiotemporal resolution of sea surface dynamic altitude are analyzed.
