With the development of aeromagnetic detection and signal processing technologies, aeromagnetic detection equipment is highly likely to have the ability to recognize the magnetic field components of the magnetic anomaly source in the near future. However, in the current research on the magnetic decoy, the two-electrode direct opening magnetic-field source cannot simulate the components of the submarine magnetic field in the air. To solve this problem, a decoy magnetic field source scheme combining three types of magnets and the two-electrode magnetic-field source are proposed, and the calculation formulas for the magnetic fields in the air have been modeled.Based on the measured data of a submarine model, the optimal parameters of all kinds of magnetic-field sources are determined by the genetic algorithm. The simulation results are then analyzed, and thermal calculations and power calculations are carried out. A comparison with the two-electrode type, as well as multi-magnet two-electrode magnetic-field sources, the single-magnet two-electrode magnetic-field source is a better structure scheme for the decoy, which can better simulate the components of the magnetic induction intensity of the target submarine when the overall structure of the magnetic-field source is relatively simple.
