• Abstract:

  When using existing methods to carry out electromagnetic compatibility anti-interference of ship's grounded electrical equipment, there are problems of low coupling and polarization matching coefficient. Therefore, a new electromagnetic compatibility anti-jamming method of ship's grounded electrical equipment is designed. First, the design of the antenna system adapted to the ship's landing electrical equipment is to design the small loop antenna. Then design the filter matching circuit, and realize the filter by matching two series capacitors. Finally, on the basis of the designed antenna system and impedance matching, the electromagnetic compatibility and anti-interference model of the ship's grounded electrical equipment is constructed to achieve the purpose of electromagnetic compatibility and anti-interference of the ship's grounded electrical equipment. The designed electromagnetic compatibility anti-jamming model is composed of receiving antenna and transmitting antenna. The coupling degree and polarization matching coefficient of this method and the existing method are tested by comparative experiments. The experimental results prove that the coupling degree and polarization matching coefficient of this method are higher than the existing method, and the performance improvement and breakthrough are realized.
