Quantitative synthetic aperture radar inversion
Liliana Borcea, Josselin Garnier, Alexander V. Mamonov +1
We study an inverse scattering problem for monostatic synthetic aperture radar (SAR): Estimate the wave speed in a heterogeneous, isotropic and nonmagnetic medium probed by waves e…
Reduced Order Modeling for First Order Hyperbolic Systems with Application to Multiparameter Acoustic Waveform Inversion
Liliana Borcea, Josselin Garnier, Alexander V. Mamonov +1
Waveform inversion seeks to estimate an inaccessible heterogeneous medium from data gathered by sensors that emit probing signals and measure the generated waves. It is an inverse…
A Krylov projection algorithm for large symmetric matrices with dense spectra
Vladimir Druskin, Jörn Zimmerling
We consider the approximation of for large s.p.d. with dense spectrum and , . We target the com…
Electromagnetic inverse wave scattering in anisotropic media via reduced order modeling
Liliana Borcea, Yiyang Liu, Jörn Zimmerling
The inverse wave scattering problem seeks to estimate a heterogeneous, inaccessible medium, modeled by unknown variable coefficients in wave equations, from transient recordings of…
Velocity estimation via model order reduction
Alexander V. Mamonov, Liliana Borcea, Josselin Garnier +1
A novel approach to full waveform inversion (FWI), based on a data driven reduced order model (ROM) of the wave equation operator is introduced. The unknown medium is probed with p…
