title = "The mean doppler velocity derived by an advanced ionospheric sounder - Dynasonde",
abstract = "The lower ionosphere was examined by using a fixed sounding frequency 7.953 MHz of the EISCAT dynasonde. The phase parameter and Doppler spectrum techniques were applied on the echoes to obtain radial Doppler velocities. It is found that the two derived velocities are very different. A procedure is developed and introduced to apply on the Doppler velocities obtained from the phase parameter technique. Result shows that mean Doppler velocities derived by the weighted mean procedure are close to those of the typical spectrum technique.",
