doppler frequency shift

常见例句

It depends on many factors whether the algorithms are efficient, such as sampling rate, receiver noise model, Doppler frequency shift etc.
去卷积方法能否在系统中应用需视系统的具体情况而定，如采样率、噪声模型及多普勒频移等。
A large Doppler frequency shift estimation algorithm was proposed, which is called large Doppler frequency shift estimation algorithm based on AR model.
给出了一种适用于卫星通信的大频偏估计算法，文中称之为基于AR模型的大频偏估计算法。
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.
相对于一般的通信系统而言，低轨卫星通信系统具有信号动态范围大，多普勒频移大且变化速度快，信道起伏剧烈等特点。

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.
