Abstract (en)
[origin: WO2009106424A1] The present invention relates to a device and a method for imaging an object using very high frequency electromagnetic radiation. Known from the prior art are imaging systems and methods comprising a synthetic aperture, wherein the signals radiated from individual transmitting antennae are differentiated from one another after reflection thereof by an object and reception at a plurality of receivers. Here, systems to accomplish this are known in which a row-like arrangement of transmitters and receivers is used, wherein an object is rotated on a motor-driven platform in front of the transmitting and receiving rows. In contrast, it is the object of the present invention to provide a device and a method for the imaging of an object, said device achieving as high a resolution as possible with as low a number of transmitters and receivers as possible. To achieve this objective, according to the invention a device for imaging of an object using very high frequency electromagnetic radiation is proposed comprising at least two receivers for the very high frequency, wherein the receivers are arranged in cells, a control unit which operated the receivers such that they produce an image in a direction parallel to the row using a synthetic aperture, and an imaging optic that is configured such that it only effects optical imaging in planes that are substantially perpendicular to the row.
