Russian technology company Roselektronika has developed a system for deactivating drones by radio waves, according to a report by Sputnik News. The Zaschita (Protection) system consists of passive sensors that do not emit any radiation and, to detect the target, uses external signals such as those of digital television that bounce off the drone. Passive sensors make the equipment practically undetectable. In addition, permission is not required for the use of radio frequencies, which facilitates its civilian use.
