Phaseless Imaging by Reverse Time Migration: Acoustic Waves
Zhiming Chen, Guanghui Huang
We propose a reliable direct imaging method based on the reverse time migration for finding extended obstacles with phaseless total field data. We prove that the imaging resolution…
Reverse Time Migration for Reconstructing Extended Obstacles in Planar Acoustic Waveguides
Zhiming Chen, Guanghui Huang
We propose a new reverse time migration method for reconstructing extended obstacles in the planar waveguide using acoustic waves at a fixed frequency. We prove the resolution of t…
Reverse Time Migration for Extended Obstacles: Electromagnetic Waves
Junqing Chen, Zhiming Chen, Guanghui Huang
We propose a new single frequency reverse time migration (RTM) algorithm for imaging extended targets using electromagnetic waves. The imaging functional is defined as the imaginar…
Reverse Time Migration for Extended Obstacles: Acoustic Waves
Junqing Chen, Zhiming Chen, Guanghui Huang
We consider the resolution of the single frequency reverse time migration (RTM) method for extended targets without the assumption of the validation of geometric optics approximati…
Two New Gradient Precondition Schemes for Full Waveform Inversion
Guanghui Huang, Huazhong Wang, Haoran Ren
We propose two preconditioned gradient direction for full waveform inversion (FWI). The first one is using time integral wavefields. The Least square problem is formulated as the t…
