Abstract

This paper is concerned with a numerical simulation of electric field distributions in urban areas by using the 1-ray model combined with 2-ray model. Introducing amplitude modification factor \( \alpha \) and propagation order \( \beta \) of distance, this model is arranged so that we can deal with propagation in complicated electromagnetic environments. We show that the two parameters \( \alpha \) and \( \beta \) can be obtained from Hata’s empirical equations. In this paper, we propose an estimation method for the electric field distributions in complicated propagation environments in addition to those areas defined by the Hata’s equations by employing statistical data such as building coverage and floor area ratios. Numerical analyses are carried out to show an example of distribution of amplitude modification factor \( \alpha \) in Fukuoka city.
