Abstract EN
A model-based imaging framework is applied to correct the target distortion seen in microwave imaging through a periodic wall structure.
In addition to propagation delays caused by the wall, it is shown that the structural periodicity induces high-order space harmonics leading to other ghost artifacts in the through-wall image.
To overcome these distortions, the periodic layer Green’s function is incorporated into the forward model.
A linear back-projection solution and a nonlinear minimization solution are applied to solve the inverse problem.
The model-based back-projection image corrects the distortion and has higher resolution compared with free space due to the inclusion of multipath propagation through the periodic wall, but considerable sidelobe clutter is present.
The nonlinear solution not only corrects target distortion without clutter but also reduces the solution to a sparse form.
