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.

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.
Geographers use satellites to study the Earth by collecting data on land use, vegetation cover, urbanization, climate patterns, and natural disasters. Satellites provide a global perspective and consistent data over time, allowing geographers to analyze and monitor changes on the Earth's surface at different scales. Geographic information obtained from satellites is used for mapping, spatial analysis, and understanding the dynamics of the Earth's systems.
