Radar

The forward facing NIIP N011M Bars (Panther) is a powerful integrated passive electronically scanned array radar. The N011M is a digital multi-mode dual frequency band radar.[4]

Features:

* The N011M can function in air-to-air and air-to-land/sea mode simultaneously while being tied into a high-precision laser-inertial or GPS navigation system. It is equipped with a modern digital weapons control system as well as anti-jamming features.
* For aircraft N011M has a 350 km search range and a maximum 200 km tracking range, and 60 km in the rear hemisphere. A MiG-21, for instance can be detected at a distance of up to 135 km. Design maximum search range for an F-16 target was 140–160 km.
* The radar can track 15 air targets and engage the 4 most dangerous simultaneously. These targets can even include cruise missiles and motionless helicopters.
* The Su-30MKI can function as a mini-AWACS as a director or command post for other aircraft. The target co-ordinates can be transferred automatically to at least 4 other aircraft.
* The radar can detect ground targets such as tanks at 40–50 km.
* The N011M is claimed to detect large sea targets at a distance up to 400 km, and small sized ones at a distance of 120 km.

The Su-30MKI can be integrated with the BrahMos cruise missile, becoming an anti-shipping platform.

Future upgrades:

* Future upgrade plans include new gimbals for the antenna mount to increase the field of view to about 90-100 degrees to both sides. New software will enable a Doppler-sharpening mode and the capability to engage up to eight air targets simultaneously.
* By 2010, when the first totally-built Su-30MKI will roll out from HAL, it could be equipped with a new phased array radar called the Irbis (Snow Leopard), which will replace the N011M Bars. These reports are yet to be confirmed by the Indian Air Force or official sources. The Irbis has been widely misreported to be an active phased array. It is not. NIIP in Vzlet, 2006 (a journal edited by noted aviation journalist A. Fomin) details the Irbis as a high power passive electronically scanned array, built using the experience of the Bars project. However, it will have a lighter antenna derived from the NIIP Osa (Wasp) radar, new servos to rotate the antenna in both axes, with a greater field of regard (adding up to a total of 100 degrees), and an entirely new architecture with dual travelling wave tubes, giving a range of 400 km against a 3 meter square target (RCS). Using new high speed computers, the Irbis will be able to track 30 targets and engage 8. It will also be KS-172 capable.

Radar modes:

* Air-to-Air : velocity search, range while search, track while scan, target ID, close combat modes.
* Air-to-Surface : Real beam mapping, DBS mapping, SAR mapping, moving ground target selection, tracking and measuring of ground target coordinates.
* Anti-shipping : Sea surface search, moving sea targets selection, tracking and measuring of sea target coordinates, sea target ID.
