The radar is a part of Sh121 multifunctional integrated radio electronic system (MIRES) onboard the Su-57. The N036 radar system is developed by Tikhomirov NIIP Institute and consists of a main nose-mounted

X-band The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of the X band is rather indefinitely set at approxim ...

AESA radar with 1,514 T/R modules, designated the N036-1-01, and two smaller X-band AESA radars with 404 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 The L band is the Institute of Electrical and Electronics Engineers (IEEE) designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz (GHz). This is at the top end of the ultra high frequency (UHF) band, at the lower en ...

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 systems information to be significantly enhanced. It has the ability to track 60 targets and shoot 16 targets in the air simultaneously, or engage up to four targets on land at the same time. The L402 "Himalayas" electronic countermeasures ( ECM) suite made by the KNIRTI institute uses both its own arrays and that of the N036 radar.Butowski 2013, p. 79. In 2012, ground tests of the N036 radar began on the third (T-50-3) and fifth (T-50-5) Su-57 prototype aircraft. Tikhomirov-NIIP has delivered six forward-looking prototype N036 Byelka radar for Su-57 fighter jets.
