摘要
利用基于弹跳射线法和一致性绕射理论的Full 3D传播模型对北京市劳动保护科学研究所附近通信基站电磁辐射场进行仿真预测。通过实测结果与仿真结果的对比分析发现,随着接收机距基站发射天线水平距离的增加,实测结果与仿真结果的变化趋势相同。当接收机距基站发射天线水平距离达到190m时,接收功率达到峰值。路径损耗的降低直接导致了接收功率的增加。
The Full 3D propagation model was used to the simulation prediction of electromagnetic radiation field for communication base station near Beijing Municipal Institute of Labor Protection. The model combined Shooting and Bouncing Ray(SBR) algorithm with the Uniform Theory of Diffraction(UTD). By comparing the field measurement results with the simulation result, it is found that the change of simulation results is the same as the change of field measurement results with increasing horizontal distance between receiver and transmitting antenna. When the horizontal distance between receiver and transmitting antenna is 190 m, the received power reaches the peak. The reduction in path loss led directly to the increase in received power.
