The latest variant of the MiG-29

being offered to India features

on AESA radar and a full suite ol

countermeasures

One of the highlights of the recentAero India 2007 Exhihit inBangalore, was the public u nveiling

ol' KSK MiG's MiG-3.^ fighter offeringtor [he Indian Medium MuhJ-RoleCombat Aircraft (MMRCA) competition.

Though the airl'rame is the same well-known MiG-29M2 "IM*. virtually the

cnlirc electronic suite of the MiG-35 wason show for the first time. The aircraftavionics system has been integrated intoihc PrNK-.^f) fire control and navigationcomplex by ihe RPKB design bureau ofRamenskoye. All devices are intercon-nected by means of data buses comp atiblewith Mil Std I553B standard controlledby a computational system made byRPKB,

AESA radar

The main fire-eontrol sensor of MiG-35is the Zhuk-AE radar with active elec-tronically scanned antenna (AESA) made

by Pha/otron-NIIR Corporation Moscow. The mock-up of a preHmivariant of this radar was shown duringMAKS exhibition al Zliukt)vskyAugust 2005. Al that time, the radar tured a 70()mm-diameter antenna prising 1,088 transmit-receive (TR) mules (272 packs, each containing modules); the antenna mirror was set20' look-up angle. This design, howturned oul lo be too heavy (450kg). Innext version the weight of indivcomponents was reduced, cutouts

made in the radar body and a lighter nesium alloy was introduced. I-'iiially

It retains the existingcomputing system with dataprocessor, signal processor andsoftware, as well as the clock gen

Phazotron will probablyoffer such an option for Zhuk-MEusers such as Yemen, Eritrea.Algeria and India.The Zhuk-AE/FGA29 is a multifunctionX-band radar (3cm wavelength), whichcan track and engage air. ground andnaval targets.

craft (radar cross-sec-tion up to 5m-).According toPhazotron. by select-ing the proper rangebetween radiatingelements, the antennabeam can be deOect-ed by +/-60 degreeswithout parasitic sidelobes. The radar canMack up to 30 air tar-gets and engage sixof them simultane-
