Abstract: The morphology of the auroral and subauroral ionosphere is strongly dependent on the interplanetary magnetic field and the level of geomagnetic activity. This change in the morphology impacts on the characteristics of signals received after propagation through these regions of the ionosphere. In order to develop a better understanding of these effects, a number of experiments have recently been undertaken in which the time of flight, Doppler frequency, and direction of arrival of HF signals have been measured over several northerly paths. In this paper, parameters derived from the observations of the channel scattering functions and direction of arrival for HF signals propagating over two paths (one in the auroral zone, and one at latitudes affected by the midlatitude trough) are presented.
