选取矩形柱体作城市楼房模型。利用广州14频道电视电波测量楼房外墙反射系数模,确定其等效电参量。用一致性几何绕射理论计算直角导电直劈绕射场,与实测数据进行比较。根据反射系数模曲线、直劈绕射场曲线,对城市电视电波传播特性进行探讨,估计可能产生的重影。
Select the rectangular column for urban building model. The use of Guangzhou 14 channel television waves measured building exterior wall reflection coefficient model to determine the equivalent electrical parameters. The diffraction field of right-angle conducting straight wedge is calculated by the consistent geometrical diffraction theory and compared with the measured data. According to the curve of the reflection coefficient model, the curve of the straight-field diffraction field is explored, and the propagation characteristics of the urban TV waves are discussed to estimate the possible ghosting.
