Where is the Doppler radar used?
Doppler radars are used in weather stations and for forecasting,predicting tornadoes,and hurricanes.
What is a portable Doppler radar?
A portable Doppler radar is a small Doppler radar mounted on the back of a truck. These radars use radio waves to capture detailed close-range images of conditions and structures inside tornadoes and other storms.
What is Doppler radar and how is it used in weather prediction and forecasting?
A Doppler radar is a radar using the Doppler effect of the returned echoes from targets to measure their radial velocity. To be more specific the microwave signal sent by the radar antenna's directional beam is reflected toward the radar and compared in frequency, up or down from the original signal, allowing for the direct and highly accurate measurement of target velocity component in the direction of the beam.Recent weather radars process velocities of precipitations by Pulse-Doppler radar technique, on top of their intensities. This is a slightly different treatment of Doppler data that has been publicized so much in the United States that the term Doppler radar is often wrongly used by the public to mean weather radar.For more info see:http://en.wikipedia.org/wiki/Doppler_radar
How much does a weather Doppler radar cost?
2 million US$ - estimate
Where was the first Doppler radar used in the US?
The exact location of where the first Doppler radar system was used cannot be determined because the first radar systems were mobile.
How does the US government help with the technology used to monitor a tornado?
Tornadoes activity is monitored largely using a network of Doppler radars. In the U.S. those radars are owned and operated by the National Weather Service, which is an agency of the federal government.

Radars can be used to detect tornadoes true or false?
True. Doppler radar can detect tornadoes.

How does science help us with the weather?
They have expensive equipment that helps a bunch: Doppler radars, sonars, satellites. How else are you gonna see if it was raining in China today...other than digging a hole?
What has the author Robert Andrew Brown written?
Robert Andrew Brown has written: 'Solid-state short-range Doppler radars'
How do Doppler radars help track and measure floods?
they have a full view of Earth they can see how much rain has fallen and how rain is going to fall
How does the Doppler effect aid police in detecting speeding motorists?
Police speed traps using Radars rely on Doppler to tell vehicle speed.
What is the difference between a Doppler radar and a regular radar?
Normal radar sends out radio waves to determine the location of an object. Doppler radar can not only find the location of an object or storm, but using something known as the Doppler effect can determine how fast it is moving towards or away from the radar.
What instruments are used to warn us about tornado occurring?
The most valuable tool is doppler radar, which can detect the rotation in a thunderstorm that can produce a tornado, and even the rotation of the tornado itself. The introduction of dual polarization in these radars can be used to detect debris lifted into the air.
What does a dolpar radar measure in units?
Do you mean Doppler radar? If so, Doppler radar measures velocity. It's a specialized radar that makes use of the Doppler effect to produce velocity data about objects at a distance. It does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the frequency of the returned signal has been altered by the object's motion. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Doppler radars are used in aviation, sounding satellites, meteorology, police speed guns, and radiology. The specific term "Doppler Radar", due in part to its extremely common use by television meteorologists in on-air weather reporting, has erroneously become popularly synonymous with the type of radar used in meteorology. Most modern weather radars use the pulse-Doppler technique to examine the motion of precipitation, but it is only a part of the processing of their data. So, while these radars use a highly specialized form of Doppler radar, the term is much broader in its meaning and its applications.

Most modern weather radars use the pulse-doppler technique to examine the motion of precipitation, but it is only a part of the processing of their data.The Doppler radar has also been applied in healthcare, such as fall detection and fall risk assessment, for nursing or clinic purpose.So, while these radars use a highly specialized form of doppler radar, the term is much broader in its meaning and its applications.
