Imaging Atmosphere and Earth's Surface with L-Band Synthetic ApertureRadar

点击翻译按钮获取中文摘要

We performed analyses of images acquired by the L-band synthetic aperture radar onboard the Japan’s Advanced Land Observing Satellite, and compared disturbances that cannot be explained by the Erath’s surface movements with the total electron content in the ionosphere derived from continuous GPS data and water vapor distribution simulated from numerical weather model. Based on the results of these analyses, we proposed methods to correct these artificial variations and detect ground surface deformation.
