N036 Byelka (Russian : Белка, 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) onboard 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, [1] 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. It has the ability to track 62 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. [1]

Airborne early warning and control Airborne system of surveillance radar plus command and control functions

An airborne early warning and control (AEW&C) system is an airborne radar picket system designed to detect aircraft, ships and vehicles at long ranges and perform command and control of the battlespace in an air engagement by directing fighter and attack aircraft strikes. AEW&C units are also used to carry out surveillance, including over ground targets and frequently perform C2BM functions similar to an Air Traffic Controller given military command over other forces. When used at altitude, the radar on the aircraft allows the operators to detect and track targets and distinguish between friendly and hostile aircraft much farther away than a similar ground-based radar. Like a ground-based radar, it can be detected by opposing forces, but because of its mobility and extended sensor range, it is much less vulnerable to counter-attacks.

Active electronically scanned array Type of phased array radar

An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).

The AN/APG-63 and AN/APG-70 are a family of all-weather multimode radar systems designed by Hughes Aircraft for the F-15 Eagle air superiority fighter. These X band pulse-Doppler radar systems are designed for both air-air and air-ground missions; they are able to look up at high-flying targets and down at low-flying targets without being confused by ground clutter. The systems can detect and track aircraft and small high-speed targets at distances beyond visual range down to close range, and at altitudes down to treetop level. The radar feeds target information into the aircraft's central computer for effective weapons delivery. For close-in dogfights, the radar automatically acquires enemy aircraft and projects this information onto the cockpit head-up display. The name is assigned from the Army Navy Joint Electronics Type Designation System.

Sukhoi Su-57 Russian fifth-generation fighter aircraft

The Sukhoi Su-57 is a stealth, single-seat, twin-engine multirole fifth-generation jet fighter being developed since 2002 for air superiority and attack operations. The aircraft is the product of the PAK FA, a fifth-generation fighter programme of the Russian Air Force. Sukhoi's internal name for the aircraft is T-50. The Su-57 is the first aircraft in Russian military service to use stealth technology. Its maiden flight took place on 29 January 2010 and it entered service on 25 December 2020. It is the world's fourth operational fifth-generation stealth fighter aircraft after the F-22, F-35, and J-20.

The AN/APG-79 Active electronically scanned array (AESA) radar is a new development for the United States Navy's Boeing F/A-18E/F Super Hornet and Boeing EA-18G Growler aircraft, providing a high level of aircrew situational awareness. The beam of the AESA radar provides nearly instantaneous track updates and multi-target tracking capability. The APG-79 AESA uses transmit/receive (TR) modules populated with Gallium arsenide Monolithic microwave integrated circuits. In the F/A-18E/F, the radar is installed in a slide-out nose rack to facilitate maintenance. It is also currently being tested on the F/A-18 C/D.

EL/M-2075 Airborne early warning and control radar system

The IAI EL/M-2075 Phalcon is an airborne early warning and control (AEW&C) active electronically scanned array radar system developed by Israel Aerospace Industries (IAI) and Elta Electronics Industries of Israel. Its primary objective is to provide intelligence to maintain air superiority and conduct surveillance. It was surpassed by newer versions—the EL/W-2085 and the EL/W-2090.

Passive electronically scanned array

A passive electronically scanned array (PESA), also known as passive phased array, is an antenna in which the beam of radio waves can be electronically steered to point in different directions, in which all the antenna elements are connected to a single transmitter and/or receiver. The largest use of phased arrays is in radars. Most phased array radars in the world are PESA. The civilian microwave landing system uses PESA transmit-only arrays.
