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.
Doppler is used in an ultrasound exam to look for and analyze movement, usually in evaluating venous or arterial blod flow.

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 did not invent Doppler Radar. He described what is now known as the Doppler effect in 1842 in Austria. It is used to describe the behavior of waves (such as light or sound) that are emitted by a moving object. Doppler radar, which utilizes the Doppler effect, was developed in the United States during World War II.
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 named after Austrian physicist Christian Doppler, who first described it in 1842.
