Radial velocity is the change in distance with respect to 'time'. But is this the time of light emission (at the star) or light reception (at the observer)? The former seems natural if radial velocity is considered a 'property' of the star, while the latter is more natural for the ...

Radar is an electronic device that uses electromagnetic waves to detect targets. The radar emits electromagnetic wave to irradiate the target and receives its echo, so as to obtain the distance, distance change rate (radial velocity), azimuth, altitude and other information from the target to the...

Re: what is Velocity Curl? #3 Ramesh. K Guest Posts: n/a Curl of a velocity represents the rigid body rotation part of the velocity gradient near a point. actually a differential change of velocity near a point is divided into three parts, linear translation rigid body rotation deformation...
Vrel is the relative velocity (m/s) λ is the wavelength (m) Due to the shorter wavelength (such as millimeter waves), the frequency shift is greater, making it easier to measure the resulting frequency shift. The ability to use smaller multi-element antennas and adaptive beamforming also ...
Computers present the information in two types of Doppler maps. In a reflectivity map, precipitation information is color coded by intensity and superimposed on a geographic map that indicates positioning. A second Doppler map displays a storm’sradial velocity, which can be used to determined wind...
