Tropospheric radiowave propagation over diffraction paths
Abstract
Measurements of field strength for a period of one year, were made over two paths in vhf band. One path (55 km) has two intervening ridges of Shivalik range and the other is a diffraction path (35 km) over curved earth. Distribution of hourly median values of one year data for both links are presented in the form of probability curves. Seasonal, monthly and diurnal variations of field strength have also been studied. The results of observations have been compared with theoretical and CCIR predictions.
