According to reports, Russia's Zavod Electromash has developed a unique drone detection system that can detect reconnaissance/attack drones while ensuring its own stealth. This is a mobile optical radar system that weighs only 20 kilograms and contains a signal receiving antenna and a hardware and software system that processes/displays complex information. The system can be loaded on tracked vehicles, small truck chassis vehicles, with a range of more than 20 kilometers and a radar accuracy of about 10 meters. Because the system does not actively generate radiation, it also uses radio silence mode when detecting, so it will not be detected and destroyed by the enemy anti-radar system, and at the same time the system can effectively detect all kinds of stealth drones.
