20110043403 | MILLIMETER WAVE CAMERA WITH IMPROVED RESOLUTION THROUGH THE USE OF THE SAR PRINCIPLE IN COMBINATION WITH A FOCUSING OPTIC - The present invention concerns an apparatus for and a method of imaging an object by means of electromagnetic very high frequency radiation. The state of the art discloses systems for and methods of imaging with a synthetic aperture, which distinguish the signals emitted by individual transmitting antennas from each other after reflection thereof by an object upon reception on a plurality of receivers. In that respect systems are known which for that purpose use a row-like arrangement of transmitters and receivers, wherein an object is rotated on a motor-driven platform in front of the transmitter or receiver row. In comparison the object of the present invention is to provide an apparatus for and a method of imaging an object, which make it possible to achieve as high a resolution as possible with as low a number of transmitters and receivers as possible. To attain that object in accordance with the invention there is proposed an apparatus for imaging an object by means of electromagnetic very high frequency radiation comprising at least two receivers for the very high frequency radiation, wherein the receivers are arranged in a row configuration, a control operating the receivers in such a way that they produce a synthetic aperture image in a direction parallel to the row and an imaging optical means which is so adapted that it causes optical imaging only in planes substantially perpendicular to the row. | 02-24-2011 |
