This presentation gives an overview of the latest multi-pass interferometric campaign at X-band acquired with the ONERA RAMSES airborne system over several areas. The thematic of this campaign is interferometric DEM computation using different baseline configurations and change detection. There are numerous challenges to achieve thus, specially the multi-date airborne acquisitions with the coregistration accuracy and the perfect control and knowledge of the trajectories and the use of the X-band with the temporal decorrelation. After an introduction, we will present the campaign, then we will describe the test sites and we will finally present results about the temporal decorrelation at X-band and interferometric acquisitions.
