N036 Byelka (Template:Lang-ru, literally Squirrel) is an advanced active electronically scanned array radar system developed by Tikhomirov NIIP for the fifth generation Sukhoi Su-57 fighter aircraft.

Design

The radar is a part of Sh121 multifunctional integrated radio electronic system (MIRES) on board the Su-57. The N036 radar system is developed by Tikhomirov NIIP Institute and consists of a main nose-mounted X-band AESA radar with 1,552 T/R modules, designated the N036-1-01, and two smaller X-band AESA radars with 358 T/R modules mounted on the sides of the forward fuselage designated N036B-1-01. The suite also has two N036L-1-01 L-band arrays on the wing's leading edge extensions that are not only used for friend-or-foe identification but also for electronic warfare purposes. Computer processing of the X- and L-band signals enable the system’s information to be significantly enhanced. Ability to track 60 targets and shoot 16 simultaneously, as well as having the ability to engage 4 targets on land simultaneously. The L402 "Himalayas" electronic countermeasures (ECM) suite made by the KNIRTI institute uses both its own arrays and that of the N036 radar.
