Reduced order model approach for imaging with waves

  title={Reduced order model approach for imaging with waves},
  author={Liliana Borcea and Josselin Garnier and Alexander V. Mamonov and J{\"o}rn T. Zimmerling},
We introduce a novel, computationally inexpensive approach for imaging with an active array of sensors, which probe an unknown medium with a pulse and measure the resulting waves. The imaging function uses a data driven estimate of the “internal wave” originating from the vicinity of the imaging point and propagating to the sensors through the unknown medium. We explain how this estimate can be obtained using a reduced order model (ROM) for the wave propagation. We analyze the imaging function… Expand


A Nonlinear Method for Imaging with Acoustic Waves Via Reduced Order Model Backprojection
A novel nonlinear imaging method for the acoustic wave equation based on model order reduction that resolves all the dynamical behavior captured by the data, so the error from the imperfect knowledge of the velocity model is purely kinematic. Expand
Robust nonlinear processing of active array data in inverse scattering via truncated reduced order models
A novel algorithm for nonlinear processing of data gathered by an active array of sensors which probes a medium with pulses and measures the resulting waves, based on a reduced order model defined by a proxy wave propagator operator that has four important properties. Expand
Untangling the nonlinearity in inverse scattering with data-driven reduced order models
The motivation of this work is an inverse problem for the acoustic wave equation, where an array of sensors probes an unknown medium with pulses and measures the scattered waves. The goal of theExpand
Reduced Order Model Approach to Inverse Scattering
A novel inversion method, based on a reduced order model (ROM) of an operator called wave propagator, because it maps the wave from one time instant to the next, at interval corresponding to the discrete time sampling of the data, is introduced. Expand
Direct, Nonlinear Inversion Algorithm for Hyperbolic Problems via Projection-Based Model Reduction
This work estimates the wave speed in the acoustic wave equation from boundary measurements by constructing a reduced-order model (ROM) matching discrete time-domain data and presents results of inversion experiments for one- and two-dimensional synthetic models. Expand

Discovering governing equations from data by sparse identification of nonlinear dynamical systems
This work develops a novel framework to discover governing equations underlying a dynamical system simply from data measurements, leveraging advances in sparsity techniques and machine learning and using sparse regression to determine the fewest terms in the dynamic governing equations required to accurately represent the data.
