Designation

Automatic detection, measurement of the coordinates (azimuth, range and elevation) and tracking of low-flying aerial objects (AO) as well as targets at medium and high altitudes, calculation of their route parameters (heading, ground speed, range rate and height), target automatic classification and target tracking under the influence of passive and active jamming within the assigned zones, output of radar information to a user according to the assigned protocol.

Design features

— the antenna system is an active planar phased antenna array (PAA);

— each transmitting element of the PAA has its own solid-state transceiver unit with digital forming of the probing signal modulation law;

— operating frequency tuning in both automatic and automated modes;

— space surveillance, detection of targets, measurement of the coordinates, recognition and calculation of target route parameters are automatic, without involvement of the operator;

— the radar can be mounted on various stationary platforms, vehicle chassis, as well as on masts moved by auxiliary transport vehicles;

— the radar’s automated workstation can be remote-located at the user’s command post.

Operation modes

The radar employs two modes of airspace surveillance in range:

— searching for UAVs and other platforms with RCS of up to 1 m² within range limits from 500 m to 20000 m;

— searching for all types of aerial targets with RCS of over 1 m² within range limits from 2500 m to 60000 m.

There are two modes of airspace surveillance in elevation:

— scanning in elevation sector from 0 to 20°;

— scanning in elevation sector from 0 to 45°.
