An imaging system operative in a frequency range starting from X band and including the terahertz region has a receiving antenna having a spheroidal reflector. One or more arrays of detectors disposed at the focus adjacent to the reflector of the receiving antenna provides for imaging targets within a range of a few meters around the second focus of the spheroidal reflector. Images of targets such as of concealed objects under clothing are generated and displayed as is known in the art. A method for manufacturing reflectors of receiving antennae given a detection range and a focal range is provided.
