Theoretical and experimental coverage analysis of a VLF transmitter
Abstract
The coverage area of a VLF transmitting station, located in the northern part of Germany, is analyzed. In order to predict the receiving skin depth for the complete operation area of the VLF station, some investigations were made in theoretical propagation models. Then a computer program based on the wave guide mode theory was implemented. To verify the validation of the theoretical model, measurements of field strength in some specific areas were carried out. The first part of the paper is concerned with a description of the theoretical approach of the coverage analysis. The second part describes some properties of the operation area and gives in detail results from measurements. Finally, a comparison of theoretical and measured data then shows the quality of agreement between theory and praxis.
