Doppler Error
</dt>
In using Doppler
radar, the error in the measurement of target radial
velocities due to atmospheric refraction. Compare range
error, azimuth
error.
</dd>
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.
