Doppler radar

from Wikipedia, the free encyclopedia

Doppler radar generally refers to a radar that has the technical requirements to use the Doppler effect . These are most radar devices today, but see in particular continuous wave radar .

Use of the term

This addition to the name only has meaning for a weather radar . Here the Doppler radars form their own, now technologically obsolete class. In older literature, the term "Doppler radar" is still used, but only to use a name for a radar device, which is only intended to state that this radar device cannot yet carry out polarimetric measurements, ie does not belong to the polarimetric radars .

For pulse radar for military or air traffic control radar devices, the suffix "Doppler" is not common, although nowadays all these radar devices can use the Doppler effect to distinguish moving targets from fixed targets or even specify targets by analyzing the entire Doppler frequency spectrum.

The manufacturers of motion detectors often call their radar modules Doppler radar sensors or Doppler radar sensor modules . All of these devices work on the principle of a continuous wave radar . The name is often misleading because some of the device applications do not take advantage of the Doppler effect, but only measure the change in the phase angle of the echo signal.
