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).
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.

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]
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 ...
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 ...
Ukrainian forces have for the first time hit a latest-generation Russian Sukhoi Su-57 fighter jet at an air base inside Russia, Kyiv's GUR defence intelligence agency said on Sunday, showing ...
Salisbury screens operate on the same principle as optical antireflection coatings used on the surface of camera lenses and glasses to prevent them from reflecting light. . The easiest to understand Salisbury screen design consists of three layers: a ground plane which is the metallic surface that needs to be concealed, a lossless dielectric of a precise thickness (a quarter of the wavelength ...
