Abstract

Based on the physical process of atmospheric signals, an algorithm has been developed to estimate the altitude-related MERIS water vapor and to correct the atmospheric effects on InSAR. The algorithm can significantly reduce the influence of atmospheric phase distortions on ASAR interferogram, and further explore the ground deformation and other geophysical signals. According to the experimental result, this altitude-related MERIS water vapor interpolation can reach 4.25% improvement averagely, relative to traditional MERIS integrated water vapor interpolation. Furthermore, this algorithm may provide an avenue for mitigate atmospheric effects in ASAR interferogram in mountainous areas, which appeals to a wide community of geophysicists.
