"Radar" comes from RAdio Detection And Ranging. If it didn't use radio it would be called something else.
LIDAR (LIght Detection And Ranging) is laser instead of radio. That uses light.

How do AM radio and television wavelengths compare with radar?
AM radio, FM radio, television, cellphones, GPS, and microwave ovens all use radio waves that are longer than the ones used for RADAR.
Do car keys use radio waves?
yes,they do use radio waves
What are the methods of finding position and movement of objects using radio waves?
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.
What is the difference between remote controls that use infrared light and those that use radio waves is?
One uses infrared light and the other uses radio waves. Hope this helps!
What do radio waves bounce off?
Radio waves are reflected by many solid objects, such as wood, stone, and notably metal, allowing the use of microwaves in radar applications.Also importantly in broadcast radio, the ionosphere (an upper layer of the Earth's atmosphere) can bounce signals back down to locations beyond the line-of-sight horizon.

What type of electromagnetic radiation is used for RADAR?
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.
What is a portable Doppler radar?
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.
Do bats use radar?
No. Bat's use ultrasound (witch is a pressure wave) rather then radio frequency (electro-magnetic waves) and therefore are more like Sonar then Radar
What is the difference between working principal of a radio altimeter and radar altimeter?
They are one in the same. They use radio waves for RAdio Detection and RAnging. Radar is an acrynom, why they flip flopped the R and the A in ranging is beyond me.They're both the same thing
What is the technology scientists use to study a hurricane by bouncing radio waves off clouds?
We use weather radar to investigate atmospheric phenomenon.
When police office officer use radar for speed control the officer is using what kind of electromagnetic wave?
radio waves
