The invention relates to a portable radiometric imaging device and to a corresponding method, finding a particular application in detecting articles carried by passengers or contained in baggage, for example in airports and train stations. The device includes a plurality of receiver antennas for picking up electromagnetic radiation from a plurality of parts of a body or an article and converting them into a plurality of signals representative of said radiation, a plurality of receiver modules associated with the antennas for receiving the signals representative of the radiation and converting them into a plurality of electrical signals, and a digital processor unit for responding to the electrical signals to create one or more digital signals representative of the electromagnetic radiation for display on a display as an image of the body or article. A correlator module is provided for correlating the electrical signals in order to form a signal representative of the electromagnetic radiation from the intersection of the two parts of the body or article.
