1) Doppler velocity
Doppler速度
1.
The backscatter of sea clutter was traditionally regarded as different from that of small targets, while the maximum amplitude, Doppler velocity and Doppler velocity Spread (DVS) of range bins hosting a target (RBHT) and all other range bins that contain only sea-clutter (AORBCS) have not been comparably studied.
传统观点认为海杂波与小目标的回波特性不同,而对于距离单元内含有小目标的海杂波与其它距离单元只含海杂波的最大幅值和Doppler速度及速度展宽没有进行比较研究。
2) Doppler velocity spread
Doppler速度展宽
3) Doppler angle
Doppler角度
1.
Wall effect of the non intrusive ultrasound Doppler velocimetry (UDV) measurements was investigated experimentally to modify the measurement error due to the wall effect in the Doppler angle and measurement location by a commercial ultrasound Doppler velocimetry.
为了校正商用超声 Doppler测速仪由于没有考虑壁效应而在 Doppler角度和测量位置的确定上引起的较大误差 ,对超声 Doppler测速仪 (UDV)在非接触式测量的壁效应进行了实验研究。
4) Laser Doppler detect velocity
激光Doppler测速
5) Doppler spectrum density
Doppler频谱密度
6) phase Doppler particle anemometer (PDPA)
相位Doppler激光测速仪
1.
The gas turbulence modulation by particles in vertical axi-symmetric sudden-expansion gas-particle flows was studied using a DANTEC 3-D phase Doppler particle anemometer (PDPA) which measured the mean and RMS gas velocities with and without heavy particles.
为了研究颗粒相的存在对气体湍流的影响,用相位Doppler激光测速仪(phaseDopplerparticleanemometer,PDPA)测量了竖直轴对称突扩通道中两相流动中的气体湍流变动,给出单相流动和气粒两相流动时的平均速度和轴向脉动速度,阐明了颗粒对气体湍流的作用,即湍流变动规律。

分子式：
CAS号：
性质： 当波源与观察者之间有相对运动时，观察者接收到的频率与波源的真实频率有所不同的物理现象。在穆斯堡尔效应中，由于原子核处于热运动，由此会引起γ谱线的多普勒展宽。
