Radar stands for RAdio Detection And Ranging. So ... radio.
Radar uses radio waves, which are a type of electromagnetic energy wave, to detect the presence, direction, distance, and speed of objects.
It is microwaves that are used for radar. They are high frequency, short wavelength electromagnetic waves, and a number of different frequency ranges of these microwaves are used depending on the application. A link is provided to the Wikipedia article on radar and the different bands or ranges of frequencies that are used and their applications.
Sound waves aren't an electromagnetic wave. So aren't seismic waves. So aren't waves in the ocean, in your hair, or waves bye-bye.
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.
Radio waves have the longest wavelength and lowest frequency among electromagnetic waves. They are used for communication, broadcasting, and radar systems.

Radar uses electromagnetic waves, specifically microwaves, to detect and track objects. These waves are emitted by a transmitter and bounce off the target object before being detected by a receiver, allowing for the measurement of the object's distance, speed, and other properties.

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.
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.

It isn't clear what type of wave you are talking about. If you mean electromagnetic waves, the answer is "radio waves".
