A preliminary study of fading of 100 megacycle FM signals

This paper describes a statistical study of the short-period fading of 100 megacycle FM signals over a mountainous propagation path under typical midday conditions. Signal intensities are found to be essentially Rayleigh distributed, while the fading increments follow a Gaussian distribution. Included are a statistical determination of the speed of fading and an effective wind velocity which may produce the fading, and a comparison of the statistically determined wind velocity with that measured by more conventional means.
