Multifunction L-Band Radar installed on ships of large displacement is designed for long-range detection and tracking of aerodynamic and ballistic targets, as well as for transmission of data to the combat management system for the purposes of anti-aircraft and anti-missile defence (AAD and AMD).
The existing Russia-made ships are so far not equipped with radars operating as part of an AMD system.
The radar is equipped with an antenna in the form of a plane active phased array (APA) installed on a rotating platform for azimuthal antenna orientation.
Two-dimensional electronic scanning provides narrow-layer angular zone coverage (with the fixed antenna) of 900 sq. deg. by elevation (by a 10° "barrier") in the azimuth sector of 90°.
Depending on the class of ship and tasks performed, the radar is "scaled" by changing the APA dimensions.
