Dear Colleagues: I want to first coregister all TerraSAR-X SLC data by SARscape(5.0)->Basic->Coregistration before putting them into SARscape(5.0)->Interferometric Stacking->Persistent Scatterers. Finally, I got the correct SLC by visual checking. As we know, the normal and temporal baselines are necessary in interferometric processing. However, these coregistered SLC data lose their original information about normal and temporal baselines. When I use SARscape(5.0)->Interferometry->Baseline Estimation, I always got unreasonable normal baseline and 0 day of temporal baseline in each InSAR pair. I suppose the SML files are modified as unexpected. I have to run several Persistent Scatterres (PS) cases containing different SLC data. My concern is that even I input the geographic coordinates there, maybe I would get different image sizes of PS products (cc/vel/height), e.g., 4999x4999 vs 5000vs5000, because each PS case has its own reference data. I was thinking of pre-coregistration might be a better solution. Look forward to see your comments. Thank you very much in advance. Chia-Hsiang Yang
