摘要
该文利用三维抛物线方程理论研究了山区无线通信中对讲机的电波传播问题。首先给出了三维抛物方程的基本理论及相关公式,接着根据刃锋绕射理论用3DPE模型对多种情况下单个山峰的电波传播特性进行了深入的研究,最后将3DPE的计算结果与菲涅尔理论值进行了有效的对比,两者的计算结果相当吻合。
Based on a three-dimensional parabolic equation(3DPE) model,the system of wireless communication in the walkie-talkie radio wave propagation in mountain has established.Firstly,the basic theory and its related formulas of the three-dimensional parabolic equation are described,and then under knife edge diffraction theory,the radio wave propagation characteristics of individual peaks was studied in terms of 3DPE model,and in the end numerical results of a three-dimensional parabolic equation(3DPE) in this pap...
