“VOSTOK-3D” 3-DIMENSIONAL RADAR

Designation: detection of air objects, measurement of their azimuth, range, altitude and flight velocities, tracking of target routes and classification of air objects, transmission of radar data to an automatic control system.

Performance capabilities:

  • detection and tracking of air objects routs within ranges of up to 360 km, 360 degrees in azimuth and −3 to 45 degrees in elevation;
  • automatic measuring of coordinates—range, azimuth and range rate by VHF-band channel, and azimuth, range and elevation by S-band channel;
  • automatic classification of tracked air objects;
  • three-channel automatic active noise jamming cancellers operating in side lobes of VHF and S-band antennas’ directional patterns, clutter rejection systems and spot jamming countermeasure systems;
  • digital generation and processing of signals, application of modern highly  efficient algorithms;
  • automatic continuous functional check of all radar devices, including identification  of faulty elements;
  • automatic radar deployment from a travelling position into a combat position  and vice versa;
  • all radar equipment, including autonomous power supply means, is located on a single all-terrain vehicle chassis.
