Drones lacking metal parts can escape radar detection.
Drones lacking metal parts can escape radar detection.
In April 2025 it was reported that [[Rostec]] began testing the “friend or foe” system for UAVs. The equipment had already passed the stage of testing for electromagnetic compatibility with the rest of the "stuffing" of the carrier drones. The key element of the new system is a [[radar]] identifier installed in the drone. At the first stage, the equipment will work with stations using the Russian state identification system. Such devices are used, for example, in [[aviation]] to distinguish friendly equipment from enemy equipment.
The equipment operates on the “friend or foe” principle and automatically marks friendly drones at an altitude of up to 5 km and a distance of up to 100 km from the radio interrogator. The transponder is lightweight - no more than 90 g - and has low power consumption. This allows the product to be integrated into a wide range of [[civilian]] and special-purpose drones, including agricultural or geodetic quadcopters.
