摘要：

A model based on the geometrical theory of diffraction is proposed for predicting radio propagation in urban microcells in the presence of undulating terrain. Comparisons with data show that the model is appropriate for predicting shadowing by terrain, but the effect of terrain fluctuations which do not obscure the line of sight is smaller than the model predicts. It is also shown that the presence of buildings lining the streets, while causing considerable variations over short distances, has only a small effect on the large-scale trend of the average signal.
