High Resolution Coherent Interferometric Imaging in Random Media

Abstract

We introduced a novel methodology for high resolution synthetic aperture radar (SAR) imaging through heterogeneous (random) media. We developed three different imaging algorithms, justified them from first principles and studied with analysis and numerical simulations their resolution and robustness to noise and to the uncertainty of the fluctuations of the wave speed. The algorithms enhance the existing imaging technology because on one hand they mitigate random multiple scattering effects and on the other hand they give resolution that is comparable to that in homogeneous (non-scattering) media.
