Observations of incoherent scattering echo-power of the MU radar and the corresponding synthetic data on 17 July 2001. (a) The radar echo-power at fixed altitudes between 384 and 411 km during 0000–1600 LT (local time). (b) The associated phase (open mark) and group (solid mark) velocities vs. altitude. (c) Synthetic wave packet at z = 1–7 and t = 1–2000. (d) The selected spectra of the MU radar echo power from 384 to 420 km altitude. The dotted symbols denote the center frequency.
