Dual-frequency car-borne DInSAR at L-band and Ku-band for mobile mapping of surface displacements

We present our recent developments and experimental results on car-borne mobile mapping of ground-surface displacements with our in-house-developed SAR systems. Recently, we have successfully demonstrated car-borne and UAV-borne DInSAR with the Gamma L-band SAR system. Meanwhile we have upgraded our car-borne measurement configuration that now permits acquiring simultaneously at L-band and at Ku-band. We show first interferometric results with short temporal baselines from simultaneous acquisitions at both frequencies and in particular we discuss the complementary aspects of the two frequencies in terms of sensitivity to line-of-sight displacements and temporal decorrelation in typical measurement scenarios.
