radar
Electromagnetic waves.
Inches (microwave) vs. Feet (Radar).
Highly energetic compared to radio waves.
Roughly within an order of magnitude or so, either way.

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
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.
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.

RADAR
Radar stands for RAdio Detection And Ranging. So ... radio.
Usually Doppler radar is used.
Radar stands for radio detection and ranging , it is used to detect the distant object with the help of electromagnetic waves. radar has a transmitter which transmit radio waves ,the waves after reflection are detected and the distance is calculated by measuring the time delay... The reflected wave get distorted due to the noise so proper prediction correlation logic is set. radar also has a control system for its rotation generally based on fuzzy control logic.
