摘要
为了精确预测TD-SCDMA移动通信基站电磁辐射的环境影响,本文在自由空间电磁辐射预测模式的基础上,引入了天线方向函数、下行占空比等参数,提出一种新的TD-SCDMA移动通信基站电磁辐射环境影响的预测模式。结果表明,与自由空间电磁辐射预测模式相比,该预测模式能更精确(相对误差由876%减至140%)的预测基站周围环境电磁辐射的三维空间分布。新预测模式不仅可为环保管理部门移动基站监测提供理论及科学依据,还能向公众普及移动通信基站电磁辐射对环境影响的知识。
To accurately predict the environmental impact of electromagnetic radiation at TD-SCDMA base station, the paper proposed a new mode to predict the environmental impact of electromagnetic radiation impact at TD-SCDMA mobile communication base station by introducing the fitting fimction of antenna direction and the downlink duty ratio parameters on the basis of electromagnetic radiation prediction model in free space. Compared with free space electromagnetic radiation prediction model, this new model could more accurately predict （relative error reduced from 876% to 140%） the three-dimensional distribution of the electromagnetic radiation environment around the base station. The new prediction mode would not only provide theoretical basis and scientific evidence for environmental management department, but also further help popularize the knowledge of environmental impact of mobile base station electromagnetic radiation.
