Ruselectronics Holding of the Rostec State Corporation has for the first time demonstrated the Guard («Защита») mobile antidrone system at the Army-2021 Forum. The system is invisible to other radars and resists electronic countermeasures owing to the use of the passive coherent location technology. The station is accommodated in three handheld cases and can be brought into the operating mode in 30 minutes.
The new system can ‘see’ an aircraft within the 360 degrees range and identify its type at a distance up to 12 km: whether it is a fixed-wing, rotary-wing or tilt-rotor one. The Guard is capable of detecting the location of the drone control panel and breaking the communication channel with the aircraft. To this end, complete frequency coverage in the range from 400 to 6,200 MHz used to control unmanned aerial vehicles is provided using the Serp subsystem. The suppression system of global satellite systems’ navigation signals is operating concurrently with suppression of UAV control channels.
Owing to the passive coherent locator, the Guard radar does not illuminate the target but rather uses signals emitted by external third-party transmitters, for example, digital TV broadcasting ones, reflected from the target. Absence of an active locator enables the system to remain invisible for enemy interceptors, which significantly lowers the probability of electronic countermeasures. Furthermore, the passive radar does not require an authorization for use of radiofrequency channels, which makes it convenient to utilize in the civil sector.
“The new system identifies and eliminates intruding drones under the sectoral principle, making possible to use it for precision suppression of specific intruding drones, as distinct from dome systems. This is one of key advantages of the Guard, allowing its use at facilities where drones are used to monitor territories, for instance. We now have several potential customers, including foreign ones, and we plan to hold a visual demonstration of system capabilities for them during the Forum,” CEO of Vega Group Vyacheslav Mikheev noted.
The Vector Research and Design Institute is developing the Guard system as part of the Vega Group.
