Radar comes from Radio Detection and Range. By definition, it uses radio waves.
Ultra sonic waves, very high frequency audio waves, are used in Sonar, the name being analogous to Radar.
Infra Sonic waves are of far too long a wavelength to be useful for any measurement of the distance of the target.
[And there are some technical reasons as well - not dealt with here.]

What are radar waves used for?
radar
What waves that are used in radar?
Electromagnetic waves.
How does the wavelength of the waves used in microwaves ovens compare with the wavelength of waves used for radar?
Inches (microwave) vs. Feet (Radar).
What kind of waves can be used in radar system?
radio waves
What are the applications of infrasonic waves?
used for forecasting natural disasters and they are also used in therapeutic devices to treat the people with physical illness :)
Why are micro waves used in RADAR?
Highly energetic compared to radio waves.
Why is ultrasonic not used in radar?
ultrasonic waves are not used but radio waves are used in radar technology because ultra sonic waves generally create an image out of the object while we have to confine our study to the geometrical measurements only
What are the applications of infrasonic sound waves?
used for forecasting natural disasters and they are also used in therapeutic devices to treat the people with physical illness :)
Waves that are used in radar?
Electromagnetic waves with a wavelength from a mm up to a few cm are used in radar. They will be reflected from a discontinuity in the electromagnet properties of space. e.g. a metal surface.
What wave is used in RADAR machines to clock the speed of cars?
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.
What is a device used to detect radio waves in space?
RADAR
How are radio waves used to detect objects in space?
radar
