Abstract :
It is well know that atmospheric phase screen(APS) effect in Small Baseline Subset (SBAS) D-InSAR processing to obtain ground deformation in long time series leads to additional interferometry phase and the unreliable result. To solve the problem above, MODIS product provide a mean to stimulate atmospheric field of SAR data for reducing the APS effect in D-InSAR processing. In this paper, 12 ENVISAT ASAR images are used to process SBAS method and 6 MODIS MOD05_L2 products are used to process atmosphere correction. A case study in the Jiaxing-Huzhou plain in Zhejiang province, China shows successfully stimulate the atmospheric field of SAR data and analysis its effect on SBAS application.
