An active electronically scanned array (AESA), is a type of phased array antenna, that 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.
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.
An aircraft is a machine that is able to fly by gaining support from the air.
Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.
In radio, an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.
In physics, attenuation or, in some contexts, extinction is the gradual loss of flux intensity through a medium.
A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth.
Direct current (DC) is the unidirectional flow of electric charge.
Interior view upward to the Byzantine domes and semi-domes of Hagia Sophia. See Commons file for annotations. A dome (from Latin: domus) is an architectural element that resembles the hollow upper half of a sphere.
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.
The DRDO Airborne Early Warning and Control System (AEWACS) is a project of India's Defence Research and Development Organisation to develop an airborne early warning and control system for the Indian Air Force.
ECHELON, originally a secret government code name, is a surveillance program (signals intelligence/SIGINT collection and analysis network) operated by the US with the aid of four other signatory nations to the UKUSA Security Agreement Given the 5 dialects that use the terms, UKUSA can be pronounced from "You-Q-SA" to "Oo-Coo-SA", AUSCANNZUKUS can be pronounced from "Oz-Can-Zuke-Us" to "Orse-Can-Zoo-Cuss".
Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied.
An electrical network is an interconnection of electrical components (e.g. batteries, resistors, inductors, capacitors, switches) or a model of such an interconnection, consisting of electrical elements (e.g. voltage sources, current sources, resistances, inductances, capacitances).
Electronics is the discipline dealing with the development and application of devices and systems involving the flow of electrons in a vacuum, in gaseous media, and in semiconductors.
Fiberglass (US) or fibreglass (UK) is a common type of fiber-reinforced plastic using glass fiber.
Foldback is a current limiting feature (a type of overload protection) of power supplies and power amplifiers.
Freezing rain is the name given to rain precipitation maintained at temperatures below freezing by the ambient air mass that causes freezing on contact with surfaces.
Freight transport is the physical process of transporting commodities and merchandise goods and cargo.
Frequency is the number of occurrences of a repeating event per unit of time.
A geodesic dome is a hemispherical thin-shell structure (lattice-shell) based on a geodesic polyhedron.
James Edward Gordon (UK, 1913–1998) was one of the founders of materials science and biomechanics, and a well-known author of three books on structures and materials, which have been translated in many languages and are still widely used in schools and universities.
KJ-2000, NATO reporting name: Mainring is a Chinese Airborne early warning and control system comprising domestically designed electronics and radars installed on a modified Ilyushin Il-76 airframe.
The term nose cone is used to refer to the forwardmost section of a rocket, guided missile or aircraft.
A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves.
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications.
A portmanteau or portmanteau word is a linguistic blend of words,, p. 644 in which parts of multiple words or their phones (sounds) are combined into a new word, as in smog, coined by blending smoke and fog, or motel, from motor and hotel.
Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects.
RAF Fylingdales is a Royal Air Force station on Snod Hill in the North York Moors, England.
Royal Air Force Menwith Hill is a Royal Air Force station near Harrogate, North Yorkshire, England, which provides communications and intelligence support services to the United Kingdom and the United States.
In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit.
The sensitivity of an electronic device, such as a communications system receiver, or detection device, such as a PIN diode, is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.
SES Broadband for Maritime is a two-way satellite broadband Internet service for use on private boats and commercial ships throughout European waters.
A signal as referred to in communication systems, signal processing, and electrical engineering is a function that "conveys information about the behavior or attributes of some phenomenon".
In radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide.
Thermal shock occurs when a thermal gradient causes different parts of an object to expand by different amounts.
In telecommunications, transmission (abbreviations: TX, Xmit) is the process of sending and propagating an analogue or digital information signal over a physical point-to-point or point-to-multipoint transmission medium, either wired, optical fiber or wireless.
In electronics and telecommunications, a transmitter or radio transmitter is an electronic device which produces radio waves with an antenna.
A tuner is a subsystem that receives radio frequency (RF) transmissions like radio broadcasts and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing, usually because a lower frequency is used on the output.
World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although conflicts reflecting the ideological clash between what would become the Allied and Axis blocs began earlier.
