Ukrainian company Unwave has introduced an advanced electronic warfare system aimed at safeguarding vehicles from drone attacks. More details can be found on the company’s website.
The solution is designed as a rooftop box that easily attaches to standard railings, enabling operation while moving or from a stationary position while maintaining the vehicle’s civilian appearance.
The manufacturer emphasizes that the system allows for universal installation on any vehicle.
This system was developed as a practical solution featuring quick connectivity and stable performance.
According to the specified characteristics, the system includes 14 modules rated at 50 W each, covering key control and video channel frequencies for drones ranging from 320-1050 MHz, 1.9-2.7 GHz, and 5.1-5.3 GHz. This dual-polarization support minimizes the chances of maintaining communication, as drone antennas can change orientation.
Reportedly, the frequency ranges 320-1050 MHz and 1.9-2.7 GHz are primarily used by FPV drones, while 2.4 GHz, 5.2 GHz, and 5.8 GHz are typical for models like Mavic and Autel. The total power output of the system is claimed to reach up to 1 kW, utilizing active cooling.
The system operates on a 28 V DC supply and can consume over 100 amps, indicating a high power demand for the electronic warfare system. The manufacturer states that the system can function for several hours without external power connections.
Among the features is a DC-DC converter for each module, allowing it to maintain full power across various battery charge levels.
The casing is made of radio-transparent plastic, with a weight of up to 100 kg and dimensions of 215×90×45 cm.
Unwave recommends using the system in conjunction with the radio-electronic reconnaissance detector “Bashur,” which has a detection range of 70 MHz-6.2 GHz and a range of up to 2 km. A fully automated scenario is described where “Bashur” detects a threat and activates jamming, while the operator receives indications and data on the control panel.
The manufacturer notes that the “Choven-2” is produced in Ukraine with minimal use of imported components, with assembly and quality control handled by its own team. There is also an option for configuring the system according to specific operational conditions.
Unwave adds that the “Choven-2” was developed based on the “Shatro” series of electronic warfare systems, originally designed for stationary or semi-mobile use. “Choven-2” is a later adaptation of these solutions into a mobile format.
It is noted that the frequency distribution may vary depending on the frontlines. Effective jamming requires covering a wide frequency range and operating at sufficient power since some drones utilize signal amplifiers.
The effectiveness of electronic warfare is also influenced by radiation angles, drone flight altitude, and terrain, which is why mobile systems are often deployed for short distances.
