Detection of air targets Detection of air targets at an altitude of 20-50 meters presents significant difficulties for air defense systems. It is necessary to use expensive "flying radars" or even more expensive space-based surveillance systems. However, a significant number of cheap "up" radio wave emitters can be used to detect the moment of passage of an aircraft or cruise missile at low altitude. Detectors determine the moment and scale of change in reflected signals, the movement of reflection from emitter to emitter, and the speed of movement. Cellular base stations can be used as part of such emitters. Here the main role is played by radiation detectors (radiation change detectors) and software. Significant cellular coverage areas (thousands of base stations) make such a detection algorithm quite possible and stable. And, probably, it is not for nothing that during an attack by low-flying missiles there are failures in communication systems. Detec
