Title: The distance attenuation of radio waves reflected from the ionosphere
Abstract: The correct expression for the distance to be used in calculating the distance attenuation of high frequency radio waves reflected at vertical incidence from the ionosphere has been calculated using ray-tracing techniques. It appears that the measured values of the electron collision frequency found by Appleton's method may be in error for both E- and F-regions. In general the measured values are too great although, for some propagation conditions, the observed values could be too small. The magnitude of the correction depends on the angle of dip, and also, to a lesser extent, on the particular ionospheric model and radio frequency.
