The term stealth in reference to reduced radar signature aircraft became popular during the late eighties when the Lockheed Martin F-117 stealth fighter became widely known. The first large scale (and public) use of the F-117 was during the Gulf War in 1991.
Stealth aircraft are still vulnerable to detection while and immediately after using their weaponry. Since stealth payload (reduced RCS bombs and cruise missiles) is not yet generally available, and ordnance mount points create a significant radar return, stealth aircraft carry all armaments internally. As soon as weapons bay doors are opened ...
Pyotr (Petr) Yakovlevich Ufimtsev (Russian: Пётр Я́ковлевич Уфи́мцев; born 8 July 1931) is a Soviet and Russian electrical engineer and mathematical physicist, best known for his pioneering work on the physical theory of diffraction (PTD), which laid the groundwork for modern stealth aircraft technology.
Project Diana marked the birth of radar astronomy later used to map Venus and other nearby planets, and was a necessary precursor to the US space program. It was the first demonstration that terrestrial radio signals could penetrate the ionosphere , [ 1 ] opening the possibility of radio communications beyond the Earth for space probes and ...
The plan position indicator, dating from the early days of radar and still the most common type of display, provides a map of the targets surrounding the radar location. If the radar antenna on an aircraft is aimed downward, a map of the terrain is generated, and the larger the antenna, the greater the image resolution.
Stealth may be vital, but so is situational awareness. For sensors, the TAI TF-X is expected to include an indigenous Aselsan AESA-class multimode radar—which can simultaneously scan and jam ...
China looks to be building a new radar system purported to have counter-stealth capabilities, analysts found. Satellite images appear to show a SIAR system on Triton Island in the South China Sea.
The other is the fifth-generation J-20 stealth combat aircraft, which was commissioned in 2016. The US has the F-22 Raptor and the F-35 Lightning II in this category of stealth fighter aircraft.
