doppler frequency shift

基本解释

It depends on many factors whether the algorithms are efficient, such as sampling rate, receiver noise model, Doppler frequency shift etc.
去卷積方法能否在系統中應用需眡系統的具躰情況而定，如採樣率、噪聲模型及多普勒頻移等。
A large Doppler frequency shift estimation algorithm was proposed, which is called large Doppler frequency shift estimation algorithm based on AR model.
給出了一種適用於衛星通信的大頻偏估計算法，文中稱之爲基於AR模型的大頻偏估計算法。
LEO satellite communication system has the properties of larger power dynamic range, larger and faster changed doppler frequency shift and rapid fluctuation compared to ordinary communication system.
相對於一般的通信系統而言，低軌衛星通信系統具有信號動態範圍大，多普勒頻移大且變化速度快，信道起伏劇烈等特點。

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.
