Hard Wall Radar Imaging: Localization of multiple objects shadowed by metallic walls with bistatic mode MIMO radar system

“Through-Wall Radar Imaging” (TWRI) has been studied extensively to reconstruct the image from the backscattered waves through the opaque dielectric wall. When the objects are located in the shadow region of the metallic wall (hard wall) where the waves can only bypass the wall via diffraction, a new problem arises as “Hard-Wall Radar Imaging” (HWRI), which has been proposed and discussed in our previous papers.
