N2 - Millimeter-waves can be used for imaging of objects at a person's body. This allows for the detection of both metallic and non-metallic objects. In order to illuminate the person from all sides either the person has to be rotated standing on a turntable (Inverse Synthetic Aperture Radar, ISAR) or a sensor is moved on a circular path around the person (Synthetic Aperture Radar, SAR). The goal of the reconstruction is to obtain information about the shape of the threats and their positions in all three dimensions. At first the reconstruction is done along range and azimuth, which span the principal surface given by the sensor configuration. Afterwards the third spatial dimension can be determined by evaluation of the interferometric phase. The application of interferometric focussing for a circular aperture, applied to the imaging of humans, is shown in the following.
