This is a similar effect to the change in frequency, hence the name Doppler radar. The wind velocity can be separated into two components known as the radial and transverse components, and these are ...
The maximum velocity that can be correctly displayed by a Doppler radar is known as the Nyquist velocity, and this is dependent on the wavelength and frequency of pulses emitted by the radar. Common ...
Since the Doppler spectrums of targets in ScanSAR are incomplete and the range of the Doppler spectrum occupied by different targets is inconsistent, the radial velocity estimation of ship targets in ...
Learn how phase noise impacts a radar system’s performance and about a way to improve it using a voltage-controlled SAW ...
With billions of children around the world anxiously waiting for their presents, Father Christmas (or Santa) and his reindeer ...
Explore the world of exoplanets—distant planets that captivate scientists. Visit ExtremeTech to learn what makes them so ...
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, ...
Gravitational pull from an orbiting planet changes the radial velocity of the star's rotation, which telescopes like Webb can detect. Exoplanets also reflect light that's Doppler shifted according ...
