Stable determination of a rigid scatterer in elastodynamics
arXiv:2007.06864 · doi:10.1137/20M1352867
Abstract
We deal with an inverse elastic scattering problem for the shape determination of a rigid scatterer in the time-harmonic regime. We prove a local stability estimate of log log type for the identification of a scatterer by a single far-field measurement. The needed a priori condition on the closeness of the scatterers is estimated by the universal constant appearing in the Friedrichs inequality.
