| 摘 要： | 通过对一段城市道路上的汽车流量提取特征参数，进行一维建模，并以GSM基站发射的电磁波信号为入射波，利用矩量法对此一维散射情况建立矩阵方程，并进行数值计算、仿真，仿真结果显示了通信基站发射的电磁波在公路上的散射场随车流量变化而发生改变的规律，并分析了由此产生的对移动通信的影响。

| Abstract: | By extracting the characteristic parameters from automobile traffic on a stretch of city roads, we set a one-dimensional model. Then we take EM waves transmitted by a GSM base station as the incident wave, and make use of Method of Moments to build matrix equations. After numerical computation and emulation, we get the law that the scattering field on the road changes according to the automobile traffic. At last, we analyze the influence of the law on mobile communications. |
