N2 - This paper demonstrates the prospects of using a Modified 3D Spherical Luneburg lens antenna for imaging. The proposed imaging experimental setup comprises the lens fed by a rectangular waveguide to shine directive beams on the targets of different shapes placed in the path of the beams. The 60 mm diameter lens with a maximum directivity of 17 dBi is enclosed in a 160 mm diameter spherical Perfectly Matched Layer. Single-frequency monostatic full-wave simulations were performed at 18 GHz. The scattering parameters and the simulated far-field data are fed to the imaging algorithm based on truncated singular value decomposition, and the reconstructed images show the imaging capabilities of a Quasi-Conformal Transformed Luneburg lens.
