摘　　要：天气雷达站产生的超标电磁辐射会对人体造成严重的损伤。为此,提出天气雷达站电磁环境影响监测与分析。分析天气雷达站电磁影响因素,结合发射天线的方向函数,构建雷达功率密度模型。测试结果表明,对于S波、C波段、X波段,真实值与计算值呈现随距离增加而降低的趋势。对于三个波的频段,当接近天线的远场区时,计算值与真实值逐渐接近,相对误差均较小,说明模型在远场区的适用性更强;研究算法与实测值的拟合程度较高;在模型的应用中,真实反映了某市区的电磁辐射情况。The excessive electromagnetic radiation generated by weather radar station can cause serious damage to human body.Therefore,the electromagnetic environmental impact monitoring and analysis of weather radar station are proposed.The electromagnetic influence factors of weather radar station are analyzed,and the radar power density model is built based on the direction function of transmitting antenna.The test results show that for S wave,C band and X band,the real value and the calculated value decrease with the increase of distance.For the three wave bands,when approaching the far field region of the antenna,the calculated values are gradually close to the real values.The relative errors are small,indicating that the model is more applicable in the far field region.The fitting degree between the research algorithm and the measured values is high.In the application of the model,the electromagnetic radiation situation of a certain city is reflected.
