Abstract :
TRANSMISSION and reception of radio signals are frequently and drastically influenced by “upper-atmosphere clutter” due to reflection from meteor and auroral ionization. As a result of such problems, Stanford Research Institute´s (SRI) Special Techniques Group has embarked on a research program to gather information about the reflections of very-high frequency (VHF) and ultrahigh frequency (UHF) radio signals from meteoric and auroral ionization.
