Domain derivative and shape reconstruction for an inverse backscattering problem for the wave equation
Roland Griesmaier, Marvin Knöller, Eliane Kummer
We consider an inverse backscattering problem for time-dependent acoustic waves with a compactly supported penetrable scattering obstacle in unbounded three-dimensional free space.…
Monotonicity-based regularization of inverse medium scattering for shape reconstruction
Roland Griesmaier, Bastian Harrach, Jianli Xiang
We consider the scattering of time-harmonic plane waves by a compactly supported inhomogeneous scattering obstacle governed by the Helmholtz equation. Given far field observations…
The factorization method and Capon's method for random source identification in experimental aeroacoustics
Roland Griesmaier, Hans-Georg Raumer
Experimental aeroacoustics is concerned with the estimation of acoustic source power distributions, which are for instance caused by fluid structure interactions on scaled aircraft…
A multifrequency MUSIC algorithm for locating small inhomogeneities in inverse scattering
Roland Griesmaier, Christian Schmiedecke
We consider an inverse scattering problem for time-harmonic acoustic or electromagnetic waves. The goal is to localize several small penetrable objects embedded inside an otherwise…
