Discovered by Austrian physicist Christian Doppler (1803-1853), this condition has a great effect on low-earth orbit (LEO) satellites as they weave towards and away from the earth. See Doppler radar.

Only after a brief overview of the Doppler effect, [Shahriar] digs into the PCB which reveals three die-on-PCB ASICs responsible for generating and receiving 77GHz FMCW signals coupled to a 2D ...

The Doppler effect causes shifts in wavelengths of sound and light, and is a major factor in demonstrating the existence of an ever-expanding universe. The theory inherited its name from the ...

Such a common experience in our everyday lives, the Doppler Effect has proved to be a major factor in demonstrating the existence of an ever-expanding universe. Simply put, the effect occurs when ...

But what about the winds inside? Researchers upgraded radars to utilize the Doppler effect to solve this problem beginning in the late 1980s in the U.S., and in the 1990s across Canada.

A system for measuring speed that is based on the Doppler effect. It is used in police radar systems as well as for measuring the velocity of hurricanes and tornadoes. See Doppler effect.

The idea has links to the Doppler effect, which can make light appear red or blue shifted depending on how the emitting object is moving relative to us, as well as the rotational Doppler effect.
