Vostok-3D

3D two-band radar

Designation

Detection of aerial objects (AOs), measurement of their azimuth, range, flight altitude and speed, tracking and classification of AOs, transmission of radar information to the integrated air defense command and control system.

Capabilities and advantages

— detection and tracking of AOs over up to 360 km ranges, within 360 degrees in azimuth and from minus 3 to 45 degrees in elevation;

— automatic measurement of primary coordinates — range, azimuth and range rate by the VHF-band channel; and azimuth, range and elevation by the S-band channel;

— automatic classification of the AOs tracked;

— three-channel automatic jamming canceller providing the VHF-and S-band antenna system sidelobes suppression, clutter rejection and anti-spot jammer functions;

— digital signal shaping and processing using state-of-the-art highly effective algorithms;

— continuous functional check (BITE) of all devices of the radar with identification of faults down to a standard replaceable element;

— highly automated setup/teardown procedure;

— all radar hardware including autonomous power supply equipment is mounted on a single self-propelled high mobility truck chassis.
