Titel
Standoff imaging of suspicious and hidden objects with electromagnetic waves in the centimetre and millimetre range
Abstract
Dangerous and illegal objects like metallic and non-metallic weapons, explosives or drugs worn by a person and hidden beneath its clothes can be detected and imaged by means of non-ionizing electromagnetic waves in the centimetre and millimetre range. Experimental investigations have been performed at frequencies of 94 GHz and 24 GHz. Scanning of the hidden objects is done with compact radar modules with standoff distances in the range of several decimetres. The objects are reconstructed three-dimensionally in short time with aperture synthesis using Fourier transform. Some examples are given for imaging of suspicious objects hidden beneath different types of clothes.
