Is Ultraviolet used for radar like the Doppler radar used in weather forecasts?

No. Doppler radars analyze the frequency shift between the transmitted microwaves and thise reflected back. The biggest obstacles for light to overcome (as apposed to radio-waves) is the transparency of water and the power required to be able to produce enough light that some of it could be reflected back. Also, you would have to use something like light refraction as a variable constant (as opposed to reflected frequency shift of sound). That's where problems begin. Infrared light has a limited frequency range (you'd be better off with white light) and would require enormous power to be able to get usable data. The other problem is that in order to get some form of accuracy, all raindrops would have to be the same size.
However, if the object you wish to track is not transparent, you could emit an IR beam in a fixed pattern (like a lattice) and measure changes in the size of the pattern to gather information from. The biggest hurdle to overcome with IR light would be IR pollution from such sources as the sun, etc. Good question otherwise.

What radar is a New generation of weather radar that is capable of detecting motion directly?
Doppler Radar
What are two tools that meteorologists use to predict the weather?
Weather balloons and Doppler Radar.
How is the national weather service helpful?
The National Weather Service provides radar, forecasts, and warnings to allow users to prepare for upcoming weather patterns.
Is Doppler radar used for finding hurricanes?
Yes, Doppler Radar can be used to find all storms!
Why do farmers rely on the weather report?
It uses information based on the Doppler RADAR (invented and designed by Andrew Doppler) to predict weather so farmers will know when the best time to plant their cops would be.
What is the Doppler radar used in?
Weather and warfare.
Which of the following would be most useful for determining the presence of a tornado?
Doppler radar!!! this is the choice right? weather satellight barometer weather balloon Doppler radar
What radar is a New generation of weather radar that is capable of detecting motion directly?
Doppler Radar
What is the difference meteorologist and station model?
A meteorologist is someone who studies weather and uses information from Doppler radar, weather satellites, computers and other instruments to make weather maps and provide forecasts. A station model indicates weather using a combination of symbols on a map.

What tool shows weather change?
Doppler Radar, Thermometer, Barometer
How do tornadoes get monitored?
Doppler weather radar is used to monitor tornadoes.
Is the Doppler radar the only satellite radar in the world?
Actually the Doppler Radar aka nexrad Next generation radar is not a satellite it is a radar. Satellites are floating around the world in space and Doppler radars are here on earth to monitor weather. As far as I know the Doppler radar is the only weather radar in the world. It is basically the only thing used for monitoring weather. I the above is not quite correct. Weather radars come in two basic types coherent and non-coherent. The Coherent radar come in Doppler Radar which can be FMCW or Active Pulse Doppler. The non coherent Pulse Radar merely aim high energy pulses at the clouds and display the returned power in a colour display. The coherent version integrates many pulses together to gain a Higher signal to Noise and to detect water drops moving in clouds. That aside, to answer the question which has nothing to do with weather radar, Doppler radar is frequency used in space verticals because its coherent processing gains in achieves help to offset the ranges it operates over, but it is not the only radar technique to be used on satellites and it depends on what the radar is trying achieve. Note that Doppler radar is non a synonymous exclusively of "nexrad Next generation radar".
How much does a weather Doppler radar cost?
2 million US$ - estimate
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
