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 1,514 T/R modules, designated the N036-1-01, and two smaller X-band AESA radars with 404 T/R modules (2,322 T/R ...
The Sukhoi Su-57 (Russian: Сухой Су-57; NATO reporting name: Felon) [5] [6] is a twin-engine stealth multirole fighter aircraft developed by Sukhoi. [7] It is the product of the PAK FA (Russian: ПАК ФА, prospective aeronautical complex of front-line aviation) programme, which was initiated in 1999 as a more modern and affordable alternative to the MFI (Mikoyan Project 1.44/1.42).
Reduce radar reflections from the airframe by the use of radar-absorbent materials (RAM) or radar-transparent materials such as plastics. Reduce radar detection from exposed internal surfaces such as the cockpit, weapons bay and engine intake ducting. Reduce infra-red and radar detection during adverse weather conditions [clarification needed]
Radiation-absorbent material (RAM), often as paints, are used especially on the edges of metal surfaces. While the material and thickness of RAM coatings can vary, the way they work is the same: absorb radiated energy from a ground- or air-based radar station into the coating and convert it to heat rather than reflect it back. [39]
The great advantage Plasma Stealth possesses over traditional radio frequency stealth techniques like low-observability geometry and use of radar-absorbent materials is that plasma is tunable and wideband. When faced with frequency hopping radar, it is possible, at least in principle, to change the plasma temperature and density to deal with ...
RAM cannot perfectly absorb radar at any frequency, but any given composition does have greater absorbency at some frequencies than others; no one RAM is suited to absorption of all radar frequencies. A common misunderstanding is that RAM makes an object invisible to radar. A radar-absorbent material can significantly reduce an object's radar ...
Nakidka is efficient in the optical, IR and radar wavelength bands up to 12 cm (4.7 in), and also reduces the radar cross section by 10 db. [ 1 ] Nakidka weighs 2 kilograms per square metre (0.41 lb/sq ft) [ 1 ] and can be deployed in 0.4–1.0 man hours per square meter.
Target modifications include radar absorbing coatings and modifications of the surface shape to either "stealth" a high-value target or enhance reflections from a decoy. [1] Dispersal of small aluminium strips called chaff is a common method of changing the electromagnetic properties of air to provide confusing radar echos.
