The "Zaseka" direction finding system is an automated radio direction finding and radio monitoring system designed to detect and determine the direction of radio emissions, including unauthorized or covert signals. The system is used for the automatic detection of unmanned aerial vehicles (UAVs), highlighting its application in security tasks and infrastructure monitoring.

 

Design Features:

• Ability to detect UAV radio emissions regardless of the type of protocol used.
• Capability to retune across frequencies.
• Function to track the movement dynamics of objects on a map.
• Availability of necessary tools for radio environment analysis, enabling the identification of UAV launch sites and flight routes.

Main technical specifications:

• The frequency range for detection is 400 - 6200 MHz.
• The detection radius for low-power commercial UAVs (100 mW) is 6 km.
• Target coordinate determination at 6 km with a root mean square error (RMSE) of 150 m.
• Detection range of radars, command and control centers, and air defense systems is up to 30 km.
• Detection range of base radio stations is up to 12 km.
• Detection range of jammers with 5 W power is 6 km.
• Detection range of Wi-Fi bridges is 5 km.
