The radar received data 1 is fed to a set of Doppler filters 2. The output of each filter is coupled to a comparator 3 which is adapted to determine the identity of the filter producing the largest Doppler level or value. The comparator is further adapted to produce a signal having a ...
Water Velocity Meter FlowTracker2 with Probe Attached The new FlowTracker®2 (FT2) handheld Acoustic Doppler Velocimeter (ADV®) has all the technology you have grown to know and trust with the original FlowTracker, but now comes with functional, modernized features (Bluetooth, GPS and large co...
Velocity measurement by vibro-acoustic Doppler A single pulsed Doppler wind lidar, deployed at the FINO1 platform in the North Sea, has been used to monitor the lateral and vertical coherence of the alo... A Nabavizadeh,MW Urban,RR Kinnick,... - IEEE 被引量: 0发表: 2012年 Myocardial ...
In this chapter, the basic theory of Doppler velocity measurements by Doppler radars is discussed, where principles of Doppler radar, measurable limit of Doppler velocity, and expansion of Doppler velocity measurement range are included. Next, methods of applying Doppler radar, i.e., the volume ...
a激光多普勒测速是一种非接触式测量技术,当光射向一个运动的物体,由运动物体散射出来的光与入射光相比,频率会发生变化,这个变化的大小与物体运动速度以及照射光与速度方向之间的夹角有关。 The laser Doppler velocity measurement is one kind of non-contact survey technology, when the photoemission to a movement...
Pulsed coherent solid-state 1.06-micron and 2.1-micron laser radar systems for remote velocity measurement A low average power, pulsed, solid-state, 1.06-micron coherent laser radar (CLR) for range and velocity measurements of atmospheric and hard targets has be... SW Henderson,RM Huffaker,MJ ...
Pulse wave velocity (PWV) measurement is widely used for the indirect assessment of arterial wall distensibility. In order to improve its measurement technique, we built a system performing the calculation of the cross-correlation function of Doppler velocity signals. In 12 normal subjects and 10 pa...
