摘要 该文利用抛物型方程方法计算了电波在三维空间中传播的路径损耗。首先分析了电波传播的空间和地理环境对电波传播的影响,其次在前人研究的基础上推导了三维抛物型方程方法的相关计算公式,并结合初始条件和吸收边界条件,采用二维傅里叶变换技术,加快了计算的速度,最后将数值计算结果与双线干涉理论值进行比较,两者符合很好。 In this paper,the three dimensional parabolic equation(3DPE) method is applied to predict the path loss of radio wave propagation.Firstly,the effects of space and geography environments on wave propagation are introduced.Secondly,basic formulas required by the three dimensional parabolic equation method are derived by combing with the initial fields and the absorbable boundary conditions,and the technique of two dimensional fast Fourier transform(FFT) is adopted to speed up the calculation.Finally,numerical...
