An Improved Method for Topography-Related Tropospheric Delay Modeling Using Adaptive Window (opens in new tab)

An improved synthetic aperture radar interferometry (InSAR)-based method for modeling and mitigating the topography-related tropospheric delay by adaptively selecting an appropriate window is proposed in this article. It adopts a coarse search and then a refined binary search to determine the optimal window size for each pixel. Moreover, the correlation between stratified delay and topography is estimated within the local window centered on the target pixel, the size of which is the determine...
