P-band repeat-pass interferometry with the DLR experimental SAR (ESAR): first results

SAR interferometry is a powerful tool for the determination of surface topography and for estimation of ground parameters. In particular the analysis of different frequencies has the capability to provide a broad set of useful information. Therefore long wavelengths like the P-band of great interest, because they often show different interactions with scatterers than shorter wavelengths like the C-band. The authors address the implementation of a P-band repeat-pass mode for the DLR´s experimental SAR (ESAR), including the problematic removal of RF-interferences in the data. Recent results on a test site in Solothurn/Switzerland are shown
