Radar is quite spectacular in telling us exactly where rain is falling by pinging precipitation with radio waves! Our weather radar can determine more than just a storm’s location, but its movement as ...

The International Isle of Man TT is a crazy motorcycle race. I mean—it's seriously ludicrous. They ride on public roads (yes, they are closed to normal traffic) such that you get these videos of bikes ...

Doppler radar. It's a million watts of power or one gigawatt. To put it into terms we can visualize: 1 million watts is 3.125 million solar panels, 431 wind turbines, 100 million LEDs, 1.3 million ...

The integration of microwave photonics into sensor and radar systems has emerged as a transformative approach to achieve high-precision measurements of Doppler frequency shift (DFS) and ...

Doppler radar uses the Doppler effect to measure the radial velocity of targets in the antenna's directional beam. The Doppler effect shifts the received frequency up or down based on the radial ...

Outside every National Weather Service (NWS) office around the U.S. stands what looks like an enormous white soccer ball, perched atop metal scaffolding several stories high. These somewhat plain ...

If you like fast cars, you may be all too familiar with the Doppler shift. It forms the basis of the police radar gun, which can work out your speed by measuring the shift in frequency of microwaves ...

The Doppler shift of sound or light waves from a moving source is familiar to physicists and non-physicists alike. Now, researchers in China and Australia have seen the more exotic inverse Doppler ...
