Atmospheric refractivity profiles and microwave propagation on a terrestrial path - Experiment and simulation

The results of experimental measurement of atmospheric refractivity profiles and microwave propagation characteristics at 11 GHz carried out recently at the Podebrady site in the Czech Republic are presented. Long term statistics of atmospheric refractivity were obtained from the tower measurement of temperature, pressure and relative humidity of air. Microwave propagation during clear air conditions was observed concurrently on the 50 km long terrestrial path Prague-Podebrady with several receivers located in different heights above the ground. Propagation of electromagnetic waves was modeled using the parabolic equation method and compared with measured data.
