Abstract

Airborne SAR surveys are often subject to severe motion errors. As the different tracks of a repeat-pass interferometric data set are acquired successively, any residual motion error has strong influences on the accuracy of the derived interferometric phase. In this paper we analyze the different error sources and present suitable compensation methods. Interferometric data acquired in L-band by the DLR´s E-SAR system are used for quantitative analysis and for the demonstration of the proposed correction methods
