High Frequency (HF) and Meteor Burst Communications in a Polar Environment
HF radio provides a low-cost, long-range communications alternative to satellite communication (SATCOM). In the polar environment, however, the frequent occurrence of dense sporadic E layers during summer in high-sunspot periods can prevent propagation in the HF band for the desired communications r...

HF radio provides a low-cost, long-range communications alternative to satellite communication (SATCOM). In the polar environment, however, the frequent occurrence of dense sporadic E layers during summer in high-sunspot periods can prevent propagation in the HF band for the desired communications ranges. During solar storms, intense radiation may induce significant D-region absorption which further reduces the utility of HF radio. These phenomena cannot be defeated by the use of automatic link establishment (ALE) HF radio equipment because of the broadband nature of these effects. The use of VHF communication techniques, such as meteor scatter, provide a viable supplement to maintain connectivity when normal ALE HF radio is ineffective.
