A Model for High Frequency Radar Auroral Clutter
A model is developed to permit estimation of the effects of irregularities in the auroral ionosphere in producing clutter experienced by Over-The Horizon radars operating at high geomagnetic latitudes. The model is used on various sources of data, including auroral radar (HF, VHF, UHF), vertical inc...
