WabInSAR

The WabInSAR incorporates GMTSAR, GAMMA and advanced InSAR processing algorithms using MATLAB. The source code for processing ALOS data acquired in Path 172 over Timpson area is provided here. This link also includes all generated interferograms as well as intermediate results obtained from applying various filtering steps to this data set. The raw data can be obtained from Alaska Satellite Facilities.  

The current version of WabInSAR used for handling Timpson data set is adapted to use GAMMA for performing SLC co-registration and interferogram generation. To acquire the version compatible with GMTSAR as well as any other questions contact the author at shirzaei@vt.edu.  

Read through these guidelines before processing. This is not a set of instructions to generate perfect deformation signals or times series. The user must adjust parameters and code as needed to obtain usable results. This guide is meant to aid the user with reasonable knowledge of InSAR and MATLAB programming and it not comprehensive.
