Satellite radar interferometry for deformation monitoring: a priori assessment of feasibility and accuracy

For practical purposes, it is necessary to define a set of guidelines to assess the feasibility of contiguous or PS radar interferometry for a specific deformation problem. This feasibility is dependent on the number of SAR data acquisitions available, their spatial and temporal baselines and observation statistics, and the expected spatial and temporal behavior of the deformation process. Here, we will discuss the evaluation procedure to assess a priori whether the techniques of contiguous and PS-InSAR are feasible for specific deformation studies in terms of precision and reliability.
