12345

The 80K6 is a vehicle-carried threedimensional all-round-looking radar system designed to detect and track airborne targets flying at low, medium and high altitudes. It can operate independently or as part of regional or nation-wide computer-aided control systems. The technology was designed and developed by the State Research and Production Complex Iskra.

If deployed with Air Defence Missile Force units, the 80K6 is used for target data generation for air defence missile weapons control systems. It can also be used by Air Force and air defence elements for air traffic control applications.

The 80K6 radar system offers performance capabilities as following:

  • The detection and tracking of air targets;
  • 3D location and cruising speed measurement of air targets in the presence of active/passive jamming or natural noise, or mix of these two;
  • Friend-or-foe air target identification;
  • Receiving flight-related information from friendly aircraft and transmitting the information to authorized users;
  • measuring the difference in flying target levels for accurate target designation;
  • determining azimuth and elevation bearings of active jamming dispensers;
  • feeding output data into autonomous imagers;
  • interoperation with command posts of local and higher nation-wide computerised control systems.

In terms of its technical characteristics and performance capabilities, the 80K6 radar system is as good as foreign-designed equivalents, while being at least fifty percent less expensive. The entire 80K radar system installation finds enough room onboard a single vehicle.

The accomplishment of very demanding performance capabilities was made possible by the employment of sophisticated state-of-the-art technical solutions, including:

  • low sidelobe digital phased array providing enhanced performance capabilities involving target location in elevation and resistance to enemy active jamming attempts;
  • a klystron with a high gain factor which is used as transmitting device, providing the required level of average transmitting power while being not bulky and consuming little power;
  • Non-conventional design and configuration of the all-pass filter, providing an enhanced target discrimination performance capability and enabling target discrimination to be performed concurrently with the measurement of targets’ range rates;
  • improved primary information pre-processing algorithms enabling processing losses to be reduced to the minimum;
  • optimized target tracking algorithms enabling the multiple target tracking performance capability to be improved significantly;
  • equipping operator workstations with colour displays, enabling operations to be performed in bright daylight.
