Abstract

The recent achievements in remote sensing of the Earth’s surface and atmosphere, as well as of the planets, became possible due to implementation of radars and radiometric systems, which are capable of distinguishing a weak electromagnetic radiation in a noisy background and because of successful development of sensitive microwave, millimeter and submillimeter wave detectors [1-22]. The detection of the remote objects, the measurement of their coordinates, the determination of their shapes and forms is usually realized with the methods of optical location. There are known two types of electromagnetic location — active and passive location.
