The Doppler circuitry determines the change in frequency and, this may only be translated into a blood velocity if the insonation angle is recorded and is included in the calculation. Nevertheless, ...

Doppler sensors have come to the front as useful devices to detect human activity ... In the selection method, the sensor is selected based on the power spectral density of the particular bandwidth, ...

higher-order spectral analysis (HOSA) techniques have been applied to weather signals to better understand their statistical properties. This approach allows for the characterization of Doppler ...

EEGLAB is an open source signal processing environment for electrophysiological signals running on Matlab and developed at the SCCN/UCSD ...

Doppler velocity images are now available on the web for a number of Doppler weather radars around Australia. This section gives some guidelines on how to interpret the images. It should be stated at ...

Velocity is a measure of the speed and direction of the precipitation toward or away from the radar. Most radars can measure reflectivity but you need a Doppler radar to measure velocity. Some 40 ...

Abstract: Time delay and Doppler shift between the echo signal and the reference signal are two most commonly used measurements in target localization for the passive radar. Doppler rate, which can be ...

For optical astronomy, the space station will be accompanied by the Xuntian telescope, which can be translated to “survey the ...
