Aggie Doppler Radar
The Aggie Doppler Radar (ADRAD) is a Doppler weather radar located on the roof of the Eller Oceanography & Meteorology Building on the Texas A&M University campus in College Station, Texas. History The Meteorology department first began its study of convective storms with the use of a 3 cm wavelength radar in the early 1950s. In 1962, they upgraded to a 10 cm, and in 1966, dual wavelength capability was added. After several modifications, the radar was placed on top of the newly completed Eller O&M Building in 1973. In 1992, the Aggie Doppler RADar was born with the installation of doppler capability. A final upgrade to the pedestal, removal of the side dishes, new processor, and work station occurred in 1997. AN/CPS-9 In the early 1950s, the department received a 3-cm weather radar, AN/CPS-9, from the US Air Force. Using this 3-cm radar, researchers studied mid-latitude mesoscale systems, severe storms, and land-falling cyclones. The AN/CPS-9 model was the firs ...

Pulse-Doppler Radar
A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics. The first operational Pulse Doppler radar was in the CIM-10 Bomarc, an American long range supersonic missile powered by ramjet engines, and which was armed with a W40 nuclear weapon to destroy entire formations of attacking enemy aircraft. Pulse-Doppler systems were first widely used on fighter aircraft starting in the 1960s. Earlier radars had used pulse-timing in order to determine range and the angle of the antenna (or similar means) to determine the bearing. However, this only worked when the radar antenna was not pointed down; in that case the reflection off the ground overwhelmed any returns from other objects. As the ground moves at the ...

Weather Radar
Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. During World War II, radar operators discovered that weather was causing echoes on their screen, masking potential enemy targets. Techniques were developed to filter them, but scientists began to study the phenomenon. Soon after the war, surplus radars were used to detect precipitation. Since then, weather radar has evolved on its own and is now used by national weather services, research departments in universities, and in television stations' weather departments. Raw images are routinely used and speciali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

AN/CPS-9
The AN/CPS-9 radar, the first radar specifically designed for meteorological use, was produced in the United States around 1949 and unveiled by the Air Weather Service (now the Air Force Weather Agency) in 1954.NOAA Legacy Timeline - 1900–196 AN/CPS-9 installations The AN/CPS-9 was installed at military bases worldwide, as well as laboratories, such as the Air Force Cambridge Research Center, the Air Force Geophysics Laboratory (AFGL), the Phillips Laboratory (PL), and all weather training facilities and universities. Fifty-six CPS-9s were produced for all services combined, and less than 50 went into operational use in the Air Force; APQ-13s had to be kept in operation at facilities that did not receive a CPS-9. The first operational CPS-9 was installed at Maxwell AFB, Alabama, on 20 June 1954; that radar remained operational for 30 years before finally being replaced on 14 July 1984 by a more modern radar, the AN/FPS-77 (Fuller 1990a). In 1966, the Air Weather Service still h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APS-2F
The AN/APS-2, originally known as ASG (air-surface, model G), was a surface search radar developed by Philco originally for use in US Coast Guard blimps to detect German submarines. It proved better than several similar models then being built, and was ordered by the RAF Coastal Command where it was known as ASV Mark V. It was used primarily on British Liberator GR bombers, where they were instrumental in closing the Mid-Atlantic Gap and the subsequent destruction of the German U-boat fleet in May/June 1943. In the post-war era, many APS-2s were passed off for other services. Some of the USA's first weather radars were modified APS-2F radars.Roger C. Whiton, et al.
