Model-Corrected Microwave Imaging through Periodic Wall Structures

International Journal of Antennas and Propagation, 2012
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 ...
