Future surface deformation and change observing scenarios
Abstract
Within the context of potential future InSAR missions, we describe (1) the desired characteristics of the earth deformation observables as outlined in the recent NASA earth science decadal survey, (2) additional desirable capabilities of a future observing system that could provide a quantum leap in geodetic quality, and (3) different imaging scenarios that warrant further definition and formulation. The range of capabilities to consider involve repeat time, spatial resolution, line-of-sight diversity, and ability to suppress confounding signals that limit the quality of the geodetic measurement. We discuss a range of solutions but emphasize the potential of large, coordinated constellations. Each satellite within such constellations may have a reduced capability relative to a single flagship satellite, but the entire observation system's measurement capability exceeds what is attainable from current or imminent missions.
