Radar is a sensor system that not only detects but also recognizes objects from a significant distance. The radar operation includes the emission of electromagnetic energy in the form of a beam and detecting the wave getting reflected after it strikes the atmosphere....
As the radar beam scans in various directions (yellow lines), it will see only the component of the wind that is toward or away from the radar along each scan. For example, the radial velocity (blue arrow) toward the radar when the beam is pointed due southward (position 6) is larger...

Severe Storm Signatures Observed by Doppler Radar in the State of São Paulo, Brazil: From Synoptic Scale to Microburst
2.2. Radar operation and analysis methodTwo X-band radars were operated 18 or 15 tilt volume scan every 6 min, and two C-band radars routinely employed volume scan every 10 min. The observed data was interpolated to an orthogonal grid with 2km spacing in horizontal and 0.5km in vertical ...
A technique is presented that uses Doppler spectra collected from a vertically pointing 94-GHz radar to reconstruct cloud and precipitation drop size distributions. A conceptual model describing the broadening of Doppler spectra by turbulence was adapted from earlier works presented in the literature. ...
