摘　　要：X波段测波雷达在海洋观测领域具有重要的应用价值,但其电磁辐射带来的影响也愈发值得关注。通过对X波段雷达工作特点进行分析,提出了使用频谱分析仪和对数周期天线组成测量系统的电磁辐射测试方案。参照国家标准对国家海洋局南澳、遮浪海洋环境监测站的X波段测波雷达电磁辐射功率密度进行了测量和分析,结果表明:X波段测波雷达对环境危害小,对公众安全性好。同时解释了短时曝露限值的含义,提出了要加强员工安全教育的建议。The X-band wave observation radar has an important value of application in the field of ocean observation, but the impact caused by its electromagnetic radiation also deserves great attention. By analyzing the working characteristics of the X-band radar, this paper puts forward an electromagnetic radiation testing scheme using a measurement system formed by a spectrum analyzer and a log-periodic antenna. Referring to the national standards, measurement and analysis have been carried out for the electromagnetic radiation power densities of the X-band wave observation radars respectively belonging to the Nan＇ao and Zhelang marine environmental monitoring stations affiliated to the State Oceanic Administration. The results show that the X-band wave observation radar has relatively small adverse effects on the environment and is safe to the public. The meaning of short-term exposure limit is also explained, and it is recommended that safety education be strengthened for the staff.
