Irbis-E radar

Role	X band Hybrid Passive electronically scanned array
National origin	Russia
Manufacturer	Tikhomirov NIIP
Designer	Tikhomirov NIIP
Status	Operational
Primary user	Russian Air Force
Developed from	Bars radar

Irbis-E (Snow Leopard) is an advanced multi-mode, hybrid passive electronically scanned array radar system developed by Tikhomirov NIIP for the Su-35 multi-purpose fighter aircraft. NIIP developed the new radar based on the Bars radar system provided to Su-30MKI/MKM/MKA aircraft.

Design

Irbis-E development started in 2004 and the first radar prototype entered flight tests on board an Su-30M2 aircraft acting as a test bed in early 2007. The resulting radar system provides air-to-air, air-to-sea and air-to-ground (ground mapping, Doppler beam sharpening and Synthetic Aperture Radar modes) modes with improved performance in intense clutter (radar) environments compared to its predecessor, the Bars system. In addition, Irbis has been designed to detect low and super-low observable/stealth airborne threats.

This is an X band multi-role radar with a passive phased antenna array (PAA) mounted on a two-step hydraulic drive unit (in azimuth and roll). The antenna device scans by an electronically controlled beam in azimuth and angle of elevation in sectors not smaller than 60°. The two-step electro-hydraulic drive unit additionally turns the antenna by mechanic means to 60° in azimuth and 120° in roll. Thus, in using the electronic control and mechanical additional turn of the antenna, the maximum deflection angle of the beam grows to 120°.^[1] The Irbis-E is a direct evolution of the BARS design, but significantly more powerful. While the hybrid phased array antenna is retained, the noise figure is slightly worse at 3.5 dB, but the receiver has four rather than three discrete channels. The biggest change is in the EGSP-27 transmitter, where the single 7-kilowatt peak power rated Chelnok TWT is replaced with a pair of 10-kilowatt peak power rated Chelnok tubes, ganged to provide a total peak power rating of 20 kilowatts. The radar is cited at an average power rating of 5 kilowatts, with 2 kilowatts CW rating for illumination. NIIP claim twice the bandwidth and improved frequency agility over the BARS, and better ECCM capability. The Irbis-E has new Solo-35.01 digital signal processor hardware and Solo-35.02 data processor, but retains receiver hardware, the master oscillator and exciter of the BARS. A prototype has been in flight test since late 2005.^[2]

Operational features

Irbis-E can detect and track up to 30 airborne targets at one time at ranges near 350~400 kilometers, and attack up to 8. In air-to-surface mode the Irbis-E provides mapping allowing to attack four surface targets with precision-guided weapons while scanning the horizon searching for airborne threats that can be engaged using active radar homing missiles.

It can detect a target with RCS 3m² at up to 350 km, (towards each other, in the area of 100 square degrees)^[3]^[4] It can detect a target with RCS 0.01m² at up to 90 km.^[5]

It is one of the most powerful PESA radar used in an operational aircraft. ^[6]
