Abstract:The management and protection of electromagnetic radiation is the important content in the construction of CINRAD radar.It is of great realistic significance to accurate measurement and ascertain the actual radiation level of the radar.With a high performance spectrum analyzer and the necessary accessories,combined with the basic theory of electromagnetic radiation measurement and the working mechanism of CINRAD/SA,a selected frequency electromagnetic radiation measurement system has be formed to measure the near-field and far-field electromagnetic radiation magnitude of the radar.And the electromagnetic radiation pollution level in the relevant points can be analyzed with reference to the relevant industry standards.The effective recommendation will be able to provide for electromagnetic radiation protection and management of the radar station,which can reference for the measurement of electromagnetic radiation by spectrum analyzer in s-band CINRAD radar and provide some useful information for the electromagnetic radiation protection of the radar station.
