Doppler radar uses the Doppler effect to measure the radial velocity of targets in the antenna's directional beam. The Doppler effect shifts the received frequency up or down based on the radial ...

Tune into any TV weather report and you’ll hear the words “Doppler radar” as meteorologists track storms across California. But how does Doppler radar work? And how accurate is it? The concept of ...

Increased arterial stiffness is observed in a number of cases. The analysis of the regional functional arterial properties is of interest to determine the role of a given risk factor on the vascular ...

Alternatively, data from all transducers can be used while limiting the focal depth, allowing more transmit-receive pulses to ...

Accurate diagnosis of a PDA requires echocardiography. Echocardiography together with Doppler and color Doppler allows assessment of patency, diameter of the DA (using color Doppler), and direction of ...

Using a spectrum analyzer for pulsed measurements has always required a careful understanding and knowledge of the parameters of the pulse signal, as well as the subsequent operation of the spectrum ...

The Indus Doppler Flow Velocity System is a high-frequency, real-time pulsed Doppler measurement tool with built-in data processing software intended to assess small animals' cardiovascular health.
