Radar

Radar is an object-detection system that uses radio wave s to determine the range, angle, or velocity of objects. It can be used to detect radio waveaircraft , ships, radio waveaircraftspacecraft , radio waveaircraftspacecraftguided missiles , radio waveaircraftspacecraftguided missilesmotor vehicle s, weather formations , and terrain. A radar system consists of a weather formationstransmitter producing electromagnetic waves in the radio or weather formationstransmittermicrowave s domain,... read more

Radar Scope

is an early cabinet 1980arcade game developed and published by 1980arcade gameNintendo in December 1979. It is a shooter that can be viewed as a cross between shooterTaito 's '' shooterTaitoSpace Invaders '' and shooterTaitoSpace InvadersNamco 's '' shooterTaitoSpace InvadersNamcoGalaxian ''. It was released in three types of arcade cabinets: upright , cockpit , and cocktail . It didn't become that popular and was considered to be a commercial failure. Contrary to popular belief, it was... read more

Radar gun

A radar speed gun (also radar gun and speed gun) is a device used to measure the speed of moving objects. It is used in law-enforcement to measure the speed of moving Handheld radar speed gunvehicle s and is often used in professional spectator sport, for things such as the measurement of bowling speeds in cricket, speed of pitched baseballs , athletes and tennis serves.A radar speed gun is a baseballsDoppler radar unit that may be hand-held, vehicle-mounted or static. It measures the speed of... read more

Scintillation (radar)

Scintillation is a fluctuation in the amplitude of a target on a amplituderadar display. It is closely related to target glint, or wander, an apparent displacement of the target from its mean position. This effect can be caused by a shift of the effective reflection point on the target, but has other causes as well. The fluctuations can be slow (scan-to-scan) or rapid (pulse-to-pulse).Scintillation and glint are actually two manifestations of the same phenomenon and are most properly linked... read more

H2S (radar)

H2S was the first , . It was developed for the 's during to identify targets on the ground for night and all-weather bombing, allowing attack outside the range of the various aids like or , which were limited to about . It was also widely used as a general navigation system, allowing landmarks to be identified at long range.The early variants of the / equipment were officially known as TR3159 (H2S Mk. I/ASV VIB) or TR3191 (H2S Mk. II). These operated in the at a wavelength of 9.1 cm (3 GHz)... read more

Lichtenstein radar

The Lichtenstein was among the earliest airborne radars available to the in and the first one utilised exclusively in the air interception role. Developed by , it was available in at least four major revisions, designated FuG 202 Lichtenstein B/C, FuG 212 Lichtenstein C-1, FuG 220 Lichtenstein SN-2 and the very rarely used FuG 228 Lichtenstein SN-3. (FuG is short for ''Funk-Gerät'', German "radio set"). The Lichtenstein series remained the only widely deployed airborne interception radar used... read more

Würzburg radar

The low- UHF band Würzburg radar was the primary ground-based UHFgun laying UHFgun layingradar for the UHFgun layingradarLuftwaffe and the Wehrmacht Heer (German Army) during Wehrmacht HeerWorld War II . Initial development took place before the war and the apparatus entered service in 1940. Eventually over 4,000 Würzburgs of various models were produced. It took its name from the city of Wehrmacht HeerWorld War IIWürzburg as most German military electronic systems had European place... read more

Freya radar

''Freya'' was an early warning radar deployed by Germany during World War II ; it was named after the Norse Goddess '' deployed by Germany during World War IIFreyja ''. During the war, over a thousand stations were built. A naval version operating on a slightly different wavelength was also developed as the ''Seetakt'' .==Development==First tests of what would become the "''Freya''" were conducted in early 1937, with initial delivery of an operational radar to the '' ''Seetakt''Kriegsmarine ''... read more

Weather radar

University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during constructionradar used to locate precipitation , calculate its motion, and estimate its type (rain, snow, precipitationhail etc.). Modern weather radars are mostly precipitationhailpulse-Doppler radar s, capable of detecting the motion... read more

Radar astronomy

Radar astronomy is a technique of observing nearby astronomical objects by reflecting microwave s off target objects and analyzing the reflections. This research has been conducted for six decades. Radar astronomy differs from microwaveradio astronomy in that the latter is a passive observation and the former an active one. Radar systems have been used for a wide range of solar system studies. The radar transmission may either be pulsed or continuous.The strength of the microwaveradio astronomyradar... read more

Radar imaging

Imaging radar is an application of which is used to create two-dimensional s, typically of landscapes. Imaging radar provides its light to illuminate an area on the ground and take a picture at radio wavelengths. It uses an antenna and digital computer storage to record its images. In a radar image, one can see only the energy that was reflected back towards the radar antenna. The radar moves along a flight path and the area illuminated by the radar, or footprint, is moved along the surface in a... read more

3D radar

3D radar provides for coverage in three dimensions, unlike the more common 2D radar. While the normal 2D radar provides range and , the 3D radar provides elevation information with range and azimuth. Applications include , and surveillance.The information provided by 3D radar has long been required, particularly for air defence and interception. Interceptors must be told the altitude to climb to before making an intercept. Before the advent of single unit 3D radars, this was achieved with separate... read more

Radar Records

Radar Records was a UK-based record label formed in late 1977 by Martin Davis (managing director) who had previously worked at record labelUnited Artists Records , and Andrew Lauder , who had previously been head of Andrew LauderA&R at the UK divisions of Andrew LauderA&RLiberty Records and United Artists. The label's first records were released in early 1978.==Overview==Radar was distributed in most of the world by WEA Records (now known as Andrew LauderA&RLiberty RecordsWarner Music Group... read more

Doppler radar

A Doppler radar is a specialized Doppler effectradar that uses the Doppler effectradarDoppler effect to produce velocity data about objects at a distance. It does this by bouncing a Doppler effectradarDoppler effectmicrowave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Doppler radars are... read more
