“VOSTOK” radar
Mobile solid-state digital VHF radar “VOSTOK” is designated for detection of air objects within coverage area of the radar, measurement of their range, azimuth and range rate, transmission of radar information into an integrated control system.
The radar can operate both in standalone mode and in automation complex.
The radar provides:
long detection range of air objects and automatic determination of coordinates – slant range and azimuth – and range rate;
automatic pickup and tracking of air objects;
automatic detection of bearings of active jammers and their tracking;
enhanced jamming immunity while active and passive jamming;
operation in automated control system;
determination of state affiliation of air objects using ground radar interrogator;
mobility and quick setup (teardown).
