Abstract-A simple procedure that suppresses artefact from ultra-wideband (UWB) synthetic aperture radar (SAR) images is proposed and verified using experimental data. The proposed imaging solution is useful for imaging small objects located in the near-field region with less ambiguity.

− This paper presents an overview of several ultrawideband (UWB) antenna systems recently developed at Chalmers for applications in future UWB radio telescopes and industry sensor imaging process.
