Abstract :
A Toroidal reflector, consisting of a tilted ellipse rotated about the vertical axis, provides for multiple, overlapping high-resolution nearfield beams that form multi-view, true multistatic mm-wave imaging for security applications. Modeled results indicate the PSF on a torso target is wide and short, allowing for quickly computed 2D images which can be stacked to reconstruct detailed 3D surfaces.
