新一代天气雷达电磁波辐射测试研究

Research on the Electromagnetic Wave Radiation of the New Generation Weather Radars

随着新一代气象雷达的建设与使用,雷达脉冲电磁波辐射已经越来越受到人们的关注。本文选取某一城市固定新一代多普勒天气雷达站做测试试验,对特定地点进行电磁波辐射测试。从测试结果来看,等效平面波功率密度和脉冲电磁波功率密度的瞬时峰值均在《电磁环境控制限值》(GB 8702-2014)所要求的范围之内,电磁环境良好。

With the construction and use of a new generation of weather radars, radar pulse electromagnetic wave radiation has received more and more attention. This paper selected a city′s fixed-generation new-generation Doppler weather radar station as a test test, and performed electromagnetic wave test on a specific location. From the test results, the instantaneous peak values of equivalent plane wave power density and pulsed electromagnetic wave power density are within the range required by the "Electromagnetic Environment Control Limits"(GB 8702-2014), and the electromagnetic environment is good.
