Type
Phased-array multimode airborne radar.

Description
The V Tikhomirov Scientific-Research Institute of Instrument Design (NIIP) N011M Bars is an X-band (8 to 12.5 GHz) multifunction, phased-array radar that incorporates an L-band (1 to 2 GHz) Identification Friend-or-Foe (IFF) channel and a 1 m diameter N11-01M antenna assembly. In full capability configuration (see following) system functionality includes air-to-air, air-to-surface and anti-shipping modes, with the former comprising velocity search, range-while-search, track-while-scan, target identification (spectral and group target resolution), target illumination (for semi-active air-to-air missiles) and close combat search and lock-on. Air-to-surface modes include real beam mapping, terrain mapping with Doppler beam sharpening, synthetic aperture, ground moving target indication, air-to-ground ranging and ground target tracking. Anti-shipping modes include sea surface search, moving target selection and air-to-surface ranging. Of these various modes, spectral air-to-air target identification is believed to be based on engine compressor face returns. As applied to the Su-30MKI, N011M Bars is understood to have been the subject of a spiral development programme that has resulted in Mks 1, 2 and 3 configurations. Here, Jane's sources report the Mk 1 variant as featuring a Russian-sourced computer (variously described as being the Ts101 or Ts200 unit) and as offering air-to-air modes only. N011M Bars Mk 2 is said to make use of the same computer and to offer a 'wider' range of functions including support for up to four simultaneous air-to-air target engagements (using the RVV-AE (NATO Reporting Name 'AA-12 Adder') active radar-guided air-to-air missile) and ground mapping. N011M Bars Mk 3 employs an Indian-sourced, Vetrivale radar computer (providing
