Differential SAR Interferometry (DInSAR) is a technique, widely applied to satellite data, which allows monitoring ground deformation with high accuracy. In the last years considerable efforts have been made to extend this technique to airborne data: several campaigns have been planned and significant results have been obtained by using sensors operating with different wavelengths. In particular, the results of the experimental campaign carried out with the OrbiSAR system over the Perugia area, center of Italy, have recently shown the potentialities of the DInSAR technique applied to airborne X-Band data. In this paper we present further results of the Perugia experiment: DInSAR interferograms relevant to a region of 16 Km (in azimuth direction) by 4 Km (in range direction) are presented and an analysis of the obtained coherence is also included.
