摘　　要：本文采用模式计算法,预测新疆某县X波段天气雷达周边功率密度的空间分布情况,并依照《电磁环境控制限值》(GB 8702-2014)中电磁辐射功率密度的公众暴露控制限值,计算雷达在不同工作模式时电磁辐射安全的防护距离。理论计算结果均表明该天气雷达的电磁辐射环境影响满足《电磁环境控制限》(GB 8702-2014)和《辐射环境保护管理导则电磁辐射监测仪器和方法》(HJ/T 10.2-1996)的要求,周边电磁辐射水平低于公众曝露的控制限值。In this paper,the mode calculation method is used to predict the spatial distribution of the power density around the x-band weather radar in a county of Xinjiang,and according to the public exposure control limit of the electromagnetic radiation power density in"electromagnetic environment control limit"(GB 8702-2014),the safe protection distance of the radar against electromagnetic radiation in different working modes is calculated.The theoretical calculation results show that the electromagnetic radiation environmental impact of the weather radar meets the requirements of"electromagnetic environment control limits"(GB 8702-2014)and"electromagnetic radiation monitoring instruments and methods for radiation environmental protection management guidelines"(HJ/T 10.2-1996),and the surrounding electromagnetic radiation level is lower than the control limits of public exposure.
