Abstract : New digital UF sounding techniques are used for the study of the high altitude and the equatorial ionosphere: Doppler and incidence angle measurements allow to identify irregularities in the ionospheric plasma and to determine their velocities. In the drift mode of observation the Digisonde with a four antenna receiving array measured the plasma bulk motion at Goose Bay. The results that the HF Doppler technique measures the plasma convection also observed by incoherent scatter and satellite techniques. Automatic scaling of Digisonde ionograms is now routinely carried out at the Goose Bay Ionospheric Observatory. The E and F region echo traces are reliably determined also under spread conditions. The Automatic Real Time Ionogram Scaler with True Height also finds all standard ionospheric parameters and the electron density profile in real time. (Author)
