 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 systems information to be significantly enhanced.
