Satellite-ground signal depolarisation at millimetre wavelengths through thunderstorms
Abstract
Measurements are reported of 30-GHz signal fading and depolarization occurring on a satellite-ground link during a period of severe thunderstorm activity. Simultaneous observations of the storms using both a PPI and a fixed-beam radar provide further evidence of the severe depolarisation caused by hydrometeors above the freezing layer. Evidence is presented for abrupt changes in the level of depolarization, which are associated with lightning strokes.
