Abstract

A measurement setup for profile reconstruction of metallic targets in the 90 GHz frequency band is proposed and tested. Inverse Synthetic Aperture Radar (iSAR) formulation is used to calculate the radar reflectivity from the measured scattered field. This reflectivity gives a spatial image of the Objet Under Test (OUT) which provides information about the profile of the OUT. Measurements are done using a planar measurement setup for mm- and sub-mm frequency bands. Aiming to test the system resolution, a metallic plate with four different size holes has been chosen as OUT. Profile reconstruction results using this measurement setup are shown.
