To reduce the impact of shaft-rate electric field (SRE) on the concealment of the ship, the SRE related ship electrical equivalent model is established, and the electrical properties are studied based on the analysis of the mechanism of SRE of the ship in this paper. The ship SRE real-time suppression is proposed based on the compensated negative potential and the real-time close-loop system for the ship SRE suppression is designed. The extremely low frequency electric field strength is reduced greatly, and the shaft-rate and its harmonics field are eliminated ultimately. Experimental results show that the ship SRE can be suppressed effectively by the system, and the concealment of the ship is enhanced. |
