A Doppler measures blood flow and is used during pregnancy to check on the baby. Radiology Lab technicians are trained specifically how to use this equipment.

In space, you can observe the Doppler effect in the form of redshift and blueshift of light from celestial objects. Redshift occurs when an object is moving away from Earth, causing its light to shift towards the red end of the spectrum, while blueshift occurs when an object is moving towards Earth, causing its light to shift towards the blue end of the spectrum. These shifts provide important information about the motion and speed of objects in space.

You may be referring to the Doppler effect. I suggest to look up "Doppler Effect" in the Wikipedia; but briefly, waves get "compressed" in the forward direction, and "elongated" in the opposite direction.
Doppler effect and Doppler radar are the two most common compound nouns for the proper adjective Doppler.

Christian Doppler
The Doppler effect describes how the frequency of a wave changes depending on the relative motion between the source of the wave and the observer. For sound waves, this effect causes a change in pitch as the source moves towards or away from the observer. For light waves, the Doppler effect causes a shift in color towards the blue end of the spectrum as objects move towards an observer and towards the red end as they move away.
The Doppler effect was discovered by Austrian physicist Christian Doppler in 1842. He observed that the frequency of sound waves changes when the source of the sound is in motion relative to the observer.
