Passive radar. Passive radar (also referred to as parasitic radar, passive coherent location, passive surveillance, and passive covert radar) is a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals.
Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, [1] visible light, radio frequency (RF) spectrum, and audio, all collectively known as stealth technology. [2] The F-117 Nighthawk was the first operational aircraft explicitly designed around stealth technology.
The AN/SPY-1[a] is a United States Navy passive electronically scanned array (PESA) 3D radar system manufactured by Lockheed Martin, and is a key component of the Aegis Combat System. The system is computer controlled and uses four complementary antennas to provide 360-degree coverage. The system was first installed in 1973 on USS Norton Sound ...
Radar jamming and deception is a form of electronic countermeasures (ECMs) that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information. Concepts that blanket the radar with signals so its display cannot be read are normally known as jamming, while ...
Stealth technology. Stealth technology, also termed low observable technology (LO technology), is a sub-discipline of military tactics and passive and active electronic countermeasures, [1] which covers a range of methods used to make personnel, aircraft, ships, submarines, missiles, satellites, and ground vehicles less visible (ideally ...
Bistatic radar is a radar system comprising a transmitter and receiver that are separated by a distance comparable to the expected target distance. Conversely, a conventional radar in which the transmitter and receiver are co-located is called a monostatic radar. [1] A system containing multiple spatially diverse monostatic or bistatic radar ...
Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a receiver) and the electronics necessary for it to find and track its target autonomously. The NATO brevity code for an air-to-air active radar homing missile launch is Fox Three.
AN/TPS-75. AN/TPS-75 radars deployed at Tobyhanna Army Depot. The AN/TPS-75 is a transportable passive electronically scanned array air search 3D radar produced in the United States. It was originally designated the TPS-43E2. Although the antenna is a radically new design from the TPS-43, the radar van itself, which houses the transmitter ...
