The only difference is laser light used in lidar instead of radio waves in radar that means in radar they are using radio waves but in lidar we are using laser light by means of near infrared, green laser like that we are using many laser pulse in lidar technology
Radio...It's the r in RADARAll of RADAR stands for RAdio Detection And RangingMost modern RADAR systems actually use Microwave for better resolution because of the shorter wavelength. There are also some LIDAR systems using either IR or visible light.But it is named RADAR because the first systems used either HF or VHF radio bands.
Radio waves
Today, we track tornadoes using a combination of eyewitness reports and Doppler radar.

R.A.D.A.R. is the acronym of RAdio Detection And Ranging. Radar is a system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain. By using innovations such as the Doppler shift of reflected waves, various properties can be determined about the relative motion of aerial and ground phenomena.
RADAR = RAdio Detection And RangingRadio waves in the microwave band are used to measure the speed of cars using a technique called "Doppler RADAR", by measuring the change in frequency of the returned waves.These waves are electromagnetic waves.
Are you talking about radar detectors? If so, they are illegal in many jurisdictions and WikiAnswers does not give information about illegal activities such as using radar detectors. If you are not talking about radar detectors, the please restate the question, giving more specifics about what kind of circuit you are talking about.
That's the principle behind RADAR (Radio Detection And Ranging). A brief, high-powerpulse of radio is transmitted, then the transmitter goes silent, and the receiver listens forthe small bit of signal reflected back from any solid object. The size and distance of thesolid object are calculated from the strength and time-lag of the reflected signal.
Radar is a noun which means a system of detection.The radar was starting to detect an incoming ship.I consulted the radar to make sure the path ahead was safe.Radar works by sending out waves and waiting to see if they return.
When the British invented toe radar, it gave them a huge advantage over the Germans in World War Two.Radar was kept a closely guarded secret by the British in World War Two, even from most allies, because nobody could be trusted.The airliner has vanished from the radar.Submarines use sonar underwater and usually have radar attached to their periscopes for surface detection.
One can easily find out the speed of the jet by just using GPS system,or by radar system which is further connected to the flight control system.
