Electronic Warfare System "DOKATKA"
The “Dokatka” EW system is a unique electronic warfare solution disguised as two spare truck wheels, enabling covert deployment even in field conditions.
Each wheel contains 4 to 6 jamming modules rated at 50 W, allowing the complete two-wheel set to support up to 12 frequency bands simultaneously across a wide operating range from 300 MHz to 6 GHz.
The system is designed for platforms that require concealed installation of EW equipment, as well as for rapid deployment at stationary or mobile positions.
OPERATION PRINCIPLE
The “Dokatka” system implements broadband signal jamming across the operating frequency range 300 to 6000 MHz.
Each jamming module delivers 50 W of output power to its corresponding antenna, either omnidirectional or directional.
Control is performed via a wired control panel with a 5 m cable and an auto detection function: the automatic system detects enemy activity → activates jamming output → disables jamming once the signal disappears.
Integrated thermal sensors, an active cooling system (fans), and a DC DC voltage stabilizer ensure safe and stable operation even under prolonged continuous load.
POWER SUPPLY AND INSTALLATION
The system is powered by batteries with a capacity ranging from 1.5 kWh to 6 kWh (Li-Ion or LiFePO4), with support for:
- charging from a 220 V mains supply;
- connection to a 12 V vehicle power system (with battery discharge protection).
High-current terminals enable quick power connection, while 4.5 m cables allow flexible placement of system components. All control buttons are moisture-protected.
ADVANTAGES OF THE “DOKATKA” SYSTEM
- Disguised as cargo wheels: ideal for covert deployment.
- Modular design: from 4 to 6 frequency bands per wheel, up to 12 bands per set.
- Autonomous operation: high-capacity batteries with charging from vehicle or mains power.
- Automatic operation: control panel with auto detection independently activates and deactivates jamming.
- Ease of installation: wheels are easy to transport and deploy.
- Protection and reliability: active cooling, power stabilization, and moisture-protected controls.
