So far, the optimal variant of efficient countering major threats from modern offensive types of weapons is development of a Multifunctional Integrated Radar (MFI Radar) for aerial and surface surveillance, target assignment and designation to air and missile defence means and guided missile weapons on the ships of various ranks. The radar system provides solution of the following tasks: self-defence and collective defence within a ship formation. Creation of MFI Radar-based contour of self-defence and collective security of air and missile defence and guided missile weapons as subsystem of automated combat management system (ACMS) of surface ship allows maximizing of efficiency of tactical countering enemy and minimizing of time consumption and energy expenditures.
The basis of MFI Radar is the radar channels with coupled active phased arrays and data processing and control system, which provides synergistic effect that consistently increases combat efficiency of MFI Radar.
MFI radar is comprised of:
- early-warning radar;
- radar designed for aerial and surface surveillance and target designation within the coverage area of anti-aircraft collective defence systems;
- radar designed for aerial and surface surveillance and target designation within the coverage area of anti-aircraft self-defence systems, as well as for control of air-defence missile system and artillery;
- multichannel passive-active optical-electronic system designed for surface and aerial surveillance and target designation via detection of laser, IR and visible radiation;
- passive radiolocation system for control of missile weapons and radio equipment;
All systems are interconnected by data processing and control system via unified protocol that provides real-time interaction between all MFI Radar systems.
MAJOR MFI RADAR TASKS:
- display of all types of current situation and its analysis for decision-making;
- management of ships, shipborne weapons and aviation within its range of combat tasks;
- creation of common information field using external sources and MFI Radar for ship armament and grouping for coordination of self-defence, collective defence and application of guided missile weapons.
S-Band Radar installed on ships of medium and large displacement is designed for detection and tracking of surface and air targets, as well as transmission of data to the combat management system of the ship (ship task formation) and to control posts.
The radar is equipped with an antenna in the form of four plane active phased arrays (APA) located on the sides of the mast-tower in the form of a truncated pyramid. Each APA scans the 100° azimuth sector, which, in the aggregate, provides circular surveillance. Depending on the class of ship and tasks performed, the radar is scaled by changing the APA dimensions.
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.
