DOPPLER ERROR

Domain	Definition
Aerospace	In using Doppler radar, the error in the measurement of target radial velocities due to atmospheric refraction. Compare range error, azimuth error.These errors result from (a) the assumption of a constant wave velocity for a nonhomogeneous atmosphere and (b) the refraction or bending of the rays such that the ray path does not coincide with the geometrical straight line between the target and the radar. Errors due to (a) are of no practical importance, and, as in the case of elevation-angle error, the effects due to (b) are negligible except for elevation angles near the horizontal. (references)
