摘　　要：为缓解公众对通信基站电磁辐射的担忧,实现辐射环境影响的仿真预测与评价,在电波暗室中,通过测试频分双工(FDD)制式双极化通信天线恒定发射规律,修正理论计算与实测数据的偏差;通过数学简化天线方向性衰减函数,拓展实现空间任意点预测计算;并通过现场监测和数据统计分析验证合格。开发仿生控制的建模程序,通过开放式设计、常规多参数调整,三维仿真展现基站电磁辐射空间等值面预测边界、垂直方向上空间和地面1.7m高度最大综合预测曲线。对基站快速选址、电磁辐射环境影响可视化预测评价及环境保护可视化有极大的参考价值,具有一定的社会效益。In order to alleviate the public’s anxiety about the electromagnetic radiation of communication base stations and realize the simulation prediction and evaluation of the radiation environment impact, in the anechoic chamber, by testing the constant emission law of the FDD system dual-polarized communication antenna, the deviation between the theoretical calculation and the measured data is corrected. The directional attenuation function of the antenna is simplified by mathematics which is extended to realize the prediction and calculation of arbitrary points in space;and it is verified to be qualified through on-site monitoring and statistical analysis of data. Through open design,conventional multi-parameter adjustments, and the three-dimensional simulation shows the prediction boundary of the space isosurface of the electromagnetic radiation of the base station, vertical space, and the largest comprehensive prediction curve of 1.7 m height on the ground are displayed. It has great reference value for rapid site selection of base stations, visualization and evaluation of environmental impact of electromagnetic radiation,visualization of environmental protection,and has certain social benefits.
