【Abstract】 A quasi 3 D model based on the ray tracing technique is presented. This model is applicable for field prediction with relatively high efficiency and accuracy in a complicated environment with arbitrarily shaped streets and buildings. A comparison between the calculated and measured results is made, which shows the effectiveness of this model.更多还原
