When exposed to periodic driving, which is the time-dependent manipulation of a system's parameters, quantum systems can ...

The AWP uses the Doppler effect to create real-time, 3D maps of wind patterns above the Earth’s surface—data that, before now, has been much more difficult to capture. But when it comes to ...

The Doppler effect is a fundamental principle behind modern radar speed ... enabling precise detection without physical contact or complex setups. Fig. 2 shows the circuit diagram of the automatic ...

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.

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.

In his book The Mathematical Universe, mathematician William Dunham wrote of John Venn’s namesake legacy, the Venn diagram, “No one in the long history of mathematics ever became better known ...

This is thanks to what’s called the Doppler effect – the way speed affects the length of waves, such as sound or light. When light changes colour due to speed, we call it redshift or blueshift ...

It’s why the pitch of a train whistle changes as it passes. Meteorologists use the “Doppler effect” with radar to determine if a raindrop is moving toward or away from the radar site.

As the car recedes, the reverse effect stretches the wave, making it sound lower. The changing pitch of the note is called the Doppler effect. It is found in many contexts and is remarkably useful.

This paper provides the results of a comprehensive investigation to quantify and evaluate the effect of Doppler shift on the available bandwidth ... and IQ constellation diagrams of the received ...
