“Irbis-E” all-weather, multifunction, full spectrum, multipurpose, in escort and firing radar control system supports:
-Escord with simultaneous firing targets in range till 350-400 km
-Electronic scanning with mechanical additional turn
-Map-making with real beam and synthesized aperture with high resolution.

| At this maximum range the radar exhibits the ability to look backwards in a sector of 30 degrees per side. In this particular case the maximum target detection range amounts to 200 km in the front hemisphere and 80 km in the two lateral and rear sectors of 30 degrees each. This range is reduced to 50 km when the radar is facing down. |
Radar control system (RCS) “IRBIS-E” flight type
- Radar control system (RCS) “IRBIS-E” is intended for solution of the following missions, in structure of integrated se of airborne equipment (SAE)
- Acquisition and tracking of radio contrasting and radio-emitting in working frequency range of radar system air, land and frequency targets
- State affiliation definition of the detected air and water-borne targets
- Interaction with guided missiles of various type of “B-B” class on high-frequency channels at the stage of start-up preparation and on flight trajectory
- Class and type of air purposes recognition on their radar-tracking “portraits” of resolution of air purposes in dense groups
- Formation of radar image (RI) of underlying surface (map) in modes of the low, average and high resolution
- Radar image “freezing” on assignment of command information system (CIS) of the aircraft with indigenous aircraft position display
- Information support of low-level flight during flight calibration and obstacle avoidance
- Detection and analysis of oncoming meteounits
- Release and reception from SAE of necessary information according to the established interconnect protocol of “training type”
