WAND (channel 17) is a television station licensed to Decatur, Illinois, United States, serving the Central Illinois region as an affiliate of NBC.Owned by Block Communications, the station maintains studios on South Side Drive in Decatur, and its transmitter is located along I-72, between Oreana and Argenta.
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
Doppler radar analysis estimated that the supercell maintained a nearly continuous high-end rotational vorticity signature, averaging 94 mph (151 km/h; 82 kn) for approximately four hours and 20 minutes, a rarity among thunderstorms that produce mesocyclonic vorticity exceeding such speeds (averaging 1.5% of all supercells).
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish 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 radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
Radar/Satellite IS: Core, Mini-Core: 2003–2022: A regional composite of visible satellite and radar data, showing the movement of weather systems and precipitation over a five-hour period; this product often alternated with the Local Doppler Radar during the Core and Mini-Core playlists. Regional Doppler XL: Core: 2000–2003
The Rapid X-band Polarimetric Radar, commonly abbreviated as RaXPol, [1] is a mobile research radar designed and operated by the University of Oklahoma, led by Howard Bluestein. RaXPol often collaborates with adjacent mobile radar projects, such as Doppler on Wheels and SMART-R . [ 2 ]
However, since humans reflect far less radar energy than metal does, these systems require sophisticated technology to isolate human targets and moreover to process any sort of detailed image. Through-the-wall radars can be made with Ultra Wideband impulse radar, micro-Doppler radar, and synthetic aperture radar (SAR). [5] Imaging radar; 3D radar
Strong mesocyclone on a thunderstorm near Tuscaloosa, Alabama, that was analyzed as fitting the characteristics of a TVS.It was associated with a tornado.. A tornadic vortex signature, abbreviated TVS, is a Pulse-Doppler radar weather radar detected rotation algorithm that indicates the likely presence of a strong mesocyclone that is in some stage of tornadogenesis.
