Abstract :
We examine the effects of tilts in the reflecting layers, by using measurements of angles of arrival on radio circuits. A simple mathematical method. Is used to establish the relationships between angle deviation, electron density gradient, frequency and transmitter-receiver range. We analyse the first results from a number of different transmission paths, and compare them with an average ionospheric model. Finally, we present a statistical study of the relative measurements of the two propagation modes (ordinary “O” and extraordinary “X”) on one type of link
