In order to quantitatively analyze the effect of the electromagnetic radiation of Xband dualpolari zation radar on the environment, on the basis of the main performance parameters of Xband weather radar, we derive electromagnetic radiation characteristics of Xband weather radar, and analyze the surrounding environment of Xband radar station. The electromagnetic radiation is monitored horizontally and vertically. The theoretical calculation and actual measurement results show that Xband radar electromagnetic radiation meets the requirements of the “Controlling Limits for Electromagnetic Environment” (GB8702-2014) and the “Guidline on Management of Radioactive Environmental Protection Electromagnetic Radiation Monitoring Instruments and Methods” (HJ/T10.2-1996). The electromagnetic radiation level is lower than the public exposure control limit value.
