What is the difference between radar and satellite?
Satellites use a camera to take pictures. A radar transmits an electronic signal that bounces off objects and returns for analysis. Both systems can detect stationary or moving objects, but the display presented on a viewing screen can differ immensely.
Who created the radar?
Heinrich Hertz
How far can radar?
This permits target detection at distances from about 500 to 2,000 nautical miles (900 to 3,700 km). Thus, an HF over-the-horizon (OTH) radar can detect aircraft at distances up to 10 times that of a ground-based microwave air-surveillance radar, whose range is limited by the curvature of the Earth.
Why do Meteorologists use radar?
Besides weather satellites, atmospheric measurements, and computer models, meteorologists use weather radar to monitor and forecast the weather. Looking at several radar images over a period of time can give clues about where and how fast the rain or snow is moving. …
What do the colors mean on my radar app?
Velocity imagery is almost always displayed with red and green colors. Red shows winds blowing away from the radar, and green shows winds blowing toward it. Stronger winds usually equate to brighter colors on the radar imagery.

Do satellites use radar?
Space-based radar is space-borne radar systems that may have any of a variety of purposes. A number of Earth-observing radar satellites, such as RADARSAT, have employed synthetic aperture radar (SAR) to obtain terrain and land-cover information about the Earth.
Does radar work underwater?
Unfortunately, Microwaves are strongly absorbed by sea water within feet of their transmission. This renders radar unusable underwater. The reason is mainly because radar has a harder time penetrating large volumes of water. Also, radar is only an active system allowing for your detection by passive sensors.

How do radars work?
Radars send out electromagnetic waves similar to wireless computer networks and mobile phones. The signals are sent out as short pulses which may be reflected by objects in their path, in part reflecting back to the radar. In that same way, the pulse reflects off precipitation and sends a signal back to the radar.
