HF/VHF Radiowave Techniques for Investigating High Latitude Ionospheric Disturbances

Abstract

The object of this contract was to develop a unified model for radio wave propagation in the 2-147 MHz band at high latitudes, especially during disturbances. This particularly included the analysis and measurement of the frequency dependence during polar cap absorption events and assessment of the effects of artificially induced perturbations on radio waves within this band. This project concentrated on single hop HF ionospheric propagation in the 2-30 MHz band and VHF meteor scatter in the 45-147 MHz band.
