Study on the Safety Protection Distance of Electromagnetic Radiation for very low Frequency Antenna Array

Very low frequency (VLF) antenna arrays are usually used for the surface ship and submarine communication, the radiation field generated by which is adversely affect the electromagnetic environment (EME). In this paper, the near field radiated by VLF antenna array is simulated by FEKO, the minimum protection distance model is constructed, and the measurement about the protection distance of the near field is verified based on GJB5313A-2017. The result shows that the minimum safety protection distance is 38.7m when the VLF antenna array is transmitted at 140kW.
