A research team has developed an extrapolation-based Doppler resolution enhancement algorithm for frequency modulated ...

Wave scattering appears practically everywhere in everyday life--from conversations across rooms, to ocean waves breaking on a shore, from colorful sunsets, to radar waves reflecting from aircraft.

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 ...

Blackmore Sensors and Analytics reported its automotive Doppler lidar system for self-driving cars surpassed expectations in real-world tests in San Francisco’s congested streets and on Bay Area ...

We have all noticed how the horn of a speeding car changes as it approaches: each wave-peak is emitted from a closer point, so the wave is “squeezed” and the pitch increases. As the car recedes, the ...

What if the speed of light is a constant only most of the time? What if gravity sometimes pushed instead of pulled? Scientists are increasingly asking what would seem like far-out questions regarding ...

Queensland University of Technology provides funding as a member of The Conversation AU. When an ambulance passes with its siren blaring, you hear the pitch of the siren change: as it approaches, the ...

A twist on the physics that cops use to clock speeding drivers can determine how fast an object is spinning. The approach could be used to protect wind turbines from damaging winds, learn about ...

Physicists at the University of California, San Diego have developed a material that, at microwave frequencies, reverses Doppler shift, Snell's law and the direction in which Cerenkov radiation is ...

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or ...
