Doppler radar[′däp·lər ′rā‚där]
A radar that makes use of the Doppler shift of an echo due to relative motion of target and radar to differentiate between fixed and moving targets and measure target velocities.
A radar that detects and interprets the Doppler effect (Doppler frequency shift) in terms of the radial velocity of a target. It differentiates between fixed and moving targets by detecting and measuring the apparent change in frequency of the reflected wave caused by the motion of the target or the observer. It can also serve as an airborne navigational aid by giving ground speed and drift. In this mode, it uses an aircraft compass system as its directional reference. The system is less accurate than the inertial navigation system, or OMEGA. See Doppler shift. See also inertial navigation system and OMEGA.
