An imaging radar works very like a flash camera in that it provides its own light to illuminate an area on the ground and take a snapshot picture, but at radio wavelengths. A flash camera sends out a pulse of light (the flash) and records on film the light that is reflected back at it through the camera lens. Instead of a camera lens and film, a radar uses an antenna and digital computer tapes to record its images. In a radar image, one can see only the light that was reflected back towards the radar antenna.
On most radar images the colors generally represent how hard it is raining or snowing.
A satellite- meter takes radar images of faults.

The National Weather Services creates these radar images for the purpose of public knowledge, they can be found everywhere. Popular places to find them are pages such as; Weather, Radar.Weather, and Intellicast.
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.
From a satalite or something in space <-- really from a satelite in space or something? my dog could've thought of that.
The radar measures the winds and precipitation inside a storm by using Doppler radar to make images of a storm.It's also used to make predictions of the later weather changes.
Radar displays show where precipitation is they also show the winds within thunderstorms which help them see rotation in a thunderstorm to pick out where a tornado is possibly forming.
Images of weather systems on television come from satellites, radar systems, and weather stations. Satellites provide a view of global weather patterns, while radar systems detect precipitation in real-time. Weather stations provide localized data and observations to enhance the accuracy of forecasts.

The planet Venus was imaged using radar because its thick atmosphere makes it difficult to observe the surface using optical telescopes. Radar can penetrate the clouds and provide detailed images of the planet's surface features. Additionally, radar can also measure the surface elevation and map the topography of Venus.
Some of the websites that offer images of Civcity Rome, the building strategy game are; IGN, Game Copy World and Game Spot. Others are Game Spy and Games Radar.
