Abstract :
Using a probabilistic approach, expressions are obtained for the time delay suffered by a signal propagating through the ionosphere at VHF. The analysis indicates that a first-moment effect (due to the average electron density) and a second-moment effect (due to fluctuations in the angles determined by Snell´s laws) superpose. The analysis then leads to three expressions for the first-moment effect, which coincide with those in use.
