The term Radar is actually an acronym for Radio Detection And Ranging. A Radar functions by transmitting an electromagnetic radiation pulse and receiving a return signal or echo of that pulse. The strength of this return signal is measured and allows us to determine size and location of objects. When using a radar to observe weather, we are able to see the severity and movement of precipitation.
Satelites generally detect infrared radiation or visible light emmitted or reflected from another object into space and provide a visual representation of this radiation. This is good for observing cloud cover and atmospheric activity.
Electronically speaking, satelites are usually passive systems while ground radars are always active systems.
A laser is a device which exploits a particular quantum mechanical process to produce a very narrow beam of bright light. Radar is a system which emits radio waves and then measures the waves that are reflected back to produce a map of the sky. Radar can be tuned to show things like aircraft (as it was originally designed to do during WWII) or even weather systems.
Doppler sonography measures sound waves and Doppler radar measures radio waves.
None of the James Bond movies are completely set in a Russian radar site, although in the film Goldeneye there is a Russian radar site which is destroyed by the satellite-weapon 'Goldeneye'.
The weather channel generally forecasts their own weather using a large team of meteorologists to cover all regions. Radar and satellite images come from NOAA (National Oceanic and Atmospheric Administration), as do all watches and warnings (they do not issue any of their own).

That would be any radar detector. If you want to detect a radar that is not being used, you need to find a psychic.
Radar Scope was created in 1979-12.
A satellite- meter takes radar images of faults.

The Difference is that Radar Satellites are just a more advanced version of Radar.

you would use a weather satellite or doppler radar.
Primarily photo or radar reconnaissance.
weather balloons, Doppler radar, and satellite imaging are some examples
