Methods of Active Protection of Small-Sized Ground Objects from Radiometric Millimeter Range Detection Systems

The method of active protection of small-sized ground objects from radiometric detection systems of millimeter range is considered. As a method, it is proposed to "illuminate" an object and the background of the earth's surface with its own source of wideband noise radiation. Implementation of this method leads to a reduction in the level of object-to-background contrast to values unacceptable for the radiometric system, which reduces the probability and range of detection of small-scale ground objects by passive radiometric systems.
