“…1; in other cases, ground reflections must be considered as shown in section 7.2 and appendix III. In actual situations, the common horizon may be a mountain ridge or similar obstacle, and such paths are sometimes referred to as "obstacle gain paths", [ Bar sis and Kir by, 1961;Dickson, Egli, Herbstreit and Wickizer, 19 53;Furutsu, 1956Furutsu, , 1959Furutsu, , 1963Kirby, Dougherty and McQuate, 1955;Rider, 1953;Ugai, 1963] .

A deterministic model for propagation in outdoor urban environments based on the Fresnel-Kirchhoff integral is presented. Both two-dimensional (2-D) and three-dimensional (3-D) formulations considering reflection and diffraction are given. The theoretical predictions are compared with 2-D and 3-D measurements and good agreement is achieved. The 3-D experiments, conducted in an anechoic chamber with scaled models representing buildings, are described in detail and provide a benchmark for comparisons with other methods.
