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.).
This radar was originally a National Weather Service (NWS) local warning radar (WSR-74C) installed in 1977. It was refurbished and upgraded to Pulse-Doppler capabilities in 1991. When the NEXRAD network replaced previous NWS radars, it was donated to the UAH Department of Atmospheric Science in 2002 and upgraded to dual-polarimetry using the ...
The first is the creation of an S-band on Wheels Network (SOWNET) featuring four quickly-deployable S-band radars with 10 cm wavelengths capable of seeing through intense precipitation. These smaller truck-mounted radars would replace a single large S-band radar, allowing for dual-Doppler analyses and quicker deployment times.
Athens is a city in and the county seat of Limestone County, in the U.S. state of Alabama; it is included in the Huntsville-Decatur-Albertville, AL Combined Statistical Area. As of the 2020 census, the population of the city is 25,406.
Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. [1] Individual objects can be detected using the Doppler effect , which causes the received signal to have a different frequency from the transmitted signal ...
Pulse Doppler radar may have 50 or more pulses between the radar and the reflector. Pulse Doppler relies on medium pulse repetition frequency (PRF) from about 3 kHz to 30 kHz. Each transmit pulse is separated by 5 km to 50 km distance. Range and speed of the target are folded by a modulo operation produced by the sampling process.
A synthetic-aperture radar is an imaging radar mounted on a moving platform. [10] SAR is a Doppler technique. It is based on the fact that "radar reflections from discrete objects in a passing radar beam field each [have] a minute Doppler, or speed, shift relative to the antenna". [11]
