From: An error analysis on nature and radar system noises in deriving the phase and group velocities of vertical propagation waves

Fig. 4.

Errors of the phase and group velocities computed from Fig. 3. (a) Synthetic with Gaussian noise, (b) synthetic with white noise, (c) observation with Gaussian noise, and (d) observation with white noise. The box plots of the upper and lower panels show the errors of phase and group velocities, respectively. The box plots illustrate the median value (solid line) and inter quartile range (bar) estimated by 100 calculations (dot) at various amplification factors.
