Abstract :
The Lee Method, recommended by ITU-R and CEPT for separation short-term and long-term component spatial variations of the field strength, was solved by Lee assuming Rayleigh distributed variations. In this paper, the method is adapted for the specific propagation conditions of ground wave at MW band, using empirical data from DRM field trials. The results complete those obtained by Lee for higher frequencies. The outcome represents the starting point for the analysis of the spatial variability and allows the development of accurate propagation models for the new digital broadcasting services.
