Austrian physicist, d. 1853 famous for his discovery of the effect of movement on perceived wavelengths

Usage examples of doppler.

And there was no Doppler shift to reveal the velocity of retreat: the far side was being pared away, not pushed away, and the new, gray borderlight was being emitted from a succession of different surfaces, not a single moving source that could act as a clock.

At the edge of the field of vision, the Doppler telemeter and accelerometer spat out their little red numbers so rapidly that it was difficult to read the indicated speed.

The tree was three meters thick, they couldn't see him, and even without his confounder gear their directional doppler and heat sensors wouldn't read through that much solid wood.

Right now, whoever was on electronic watch would be getting signals from Khadaji's confounder andif they were awakewondering what the Doppler ghosts were fuzzing the screen.

Then I think we can do it, but their radar sets arent going to get as good a paint off of an aircraft as standard ground radar would, and theyre not set up for air traffic-quality doppler.

It imposes a slight Doppler shift on the microwave background radiation.

I knew enough basic science to have expected a Doppler effect, but this was a false effect, since we had not been anywhere near the speed of light until translation to C-plus and were now far beyond it within the Hawking fold.

Either the big bang theory can be proved by the red shift, in which case all matter was originally compressed into one lump, or there was no big bang and then nothing can be deduced from the red shift or the Doppler effect.

Flows of glowing matter popped suddenly in and out of visibility, as the Doppler effect took the emission lines of the gas into and then out of coincidence with the spectral line being used for observation.

The Sniffer measured the Doppler frequency shift of Earth's beacon signal and approved it.

The pulse Doppler attack radar signaled lock-on, and firing information was instantly fed to the AA-7 radar-guided missile.

He'd never used doppler sensors or particle sifters or - was that a dimensional stress indi cator?

We have no Doppler shift with respect to the target star, and the microwave background radiation is close to isotropic.

It is conceivable that this additional rapid movement of the listening surface relative to the target causes useful modulations in the Doppler shift, modulations that supply additional information.

Utilising a cross polarization of beta-particles with minimal doppler shift, due to its advanced pseudopodia,’ said the Time Sprout, informatively.
