Time reversal based direct imaging method

Prof. Hongkai Zhao Department of Mathematics

I will present a direct imaging method using multistatic measurements of scattered wave field. Our method is based on physical factorization of the scattered wave field and principal component analysis. We also introduce a threshholding strategy based on physical resolution. Our method does not need forward solver or iterations. It can deal with both near field and far field data. Efficiency and robustness of our method will be demonstrated by numerical experiments.
