Doppler shift

基本解释

Imagine now you can make the Doppler shift measurements of both stars.
假设现在你可以,对双星进行，多普勒顿移的测量。
And so you get all this useful information in astronomy by making the Doppler shift measurements of binary systems.
你们可以得到所有,天文学中的有用信息,只要对双星系统进行,多普勒顿移。
If you have a binary system whereby both stars are visible so you get the spectrum of both stars, then you see the Doppler shift of both stars in the spectrum.
若存在一个双星系统,两颗恒星均看不见,你能得到双星的光谱，然后在光谱中看到,双星的多普勒顿移。

There is a doppler shift when the recipient is moving and this can be a significant issue.

This is due to a Doppler shift—the same phenomenon that causes the pitch of an ambulance's siren to seem to vary as it passes a stationary listener.
ECONOMIST: Extrasolar planets
And since a moving object causes a tiny change (known as a Doppler shift) in the frequency of the reflected signal, Silent Sentry can also calculate how fast it is moving.

多普勒频移
Simulation result shows that the system has a good performance in multi-path fading and Doppler shift channel.
仿真结果表明，这个系统在同时存在多径衰落和多普勒频移的恶劣信道环境下仍有较好的性能。
