Combinaison des techniques PSinSAR et GNSS par cumul des équations normales

Abstract : Combining InSAR/GNSS is a popular research topic and for good reasons, the two techniques seem to be complementary in many aspects. The purpose of this study is to demonstrate the feasibility of a combination PSinSAR/GNSS. The basis of our thinking is the STUN (Spatial and Temporal Unwrapping Network) algorithm. Developed by Bert M. KAMPES, it relies on the well-known phase differences principles to reduce the effect of spatially correlated phenomena. This technique is similar to the differential GNSS positioning. We want to combine the two methods by normal equations stacking. Two algorithms are proposed. The first integrates GNSS to STUN by stacking normal matrices that have reached convergence. The second is a complete overhaul of STUN in which we have made numerous changes. It combines radar and GNSS observations at each iteration. The algorithms have been computerized and tested on simulated data. Currently, the programs do not allow real data processing but some improvements would provide operational codes from which it would be possible to quantify the contribution of PSinSAR/GNSS combination.
