A coherent change detection analysis using multi-pass airborne interferometric data at X-band

Abstract:
This paper presents results obtained during the latest multi-pass interferometric campaign at X-band acquired with the ONERA RAMSES airborne system over several areas. An objective of this campaign is to study the coherent change detection between different acquisitions. There are numerous challenges to achieve thus, specially the multi-date airborne acquisitions with the co-registration accuracy, the perfect control and knowledge of the trajectories and the use of the X-band with temporal decorrelation. We will first present the sensor and the campaign preparation, then we will describe in details the test sites and the correlated ground activities and finally we will present some results about coherent change detection analysis using some dataset acquired during this campaign over different regions of interest.
