This paper deals with the problem of accurate contour reconstruction from scattered field measurements. For this goal, an advanced SAR processing method featuring two new approaches is proposed. First, the combination of the phasefronts of the SAR image with its amplitude is used to create an initial guess of the possible positions of the contour facets. Second, a virtual focusing of the field scattered...
A novel millimeter-wave portal for human body imaging is presented in this work. Its aim is to produce accurate geometric reconstruction of the human body torso and body-borne objects concealed under clothing with size as small as 1 cm. For this purpose, a multistatic Synthetic Radar Aperture (SAR) imaging system working in the 56–64 GHz frequency band has been designed and manufactured. A novel elliptic-parabolic...
