The invention provides a closed-loop degaussing method based on a stress monitoring system. The method comprises a step of determining the positions of sensors for measuring the hull stress in the stress monitoring system and then obtaining relationships between a hull stress change and a fixed magnetic field and an induced magnetic field at these installation positions based on a simulation calculation method and / or an experimental method, a step of obtaining relationships between the fixed magnetic field and the induced magnetic field at these installation positions and magnetic characteristics at a specified distance outside a hull through simulation calculation and / or experiment, and a step of connecting a closed-loop degaussing system and the stress monitoring system to a network to get real-time hull magnetic features. According to the method, a magnetic sensor is not needed or a small amount of magnetic sensors are used in cooperation, the measurement resources of the stress monitoring system is fully used to obtain the high-precision magnetic characteristics, and the closed-loop degaussing control effect is improved.
Description
technical field [0001] The invention relates to the technical field of ship underwater feature protection, in particular to a closed-loop degaussing method based on a stress monitoring system. Background technique [0002] Changing a ship's magnetic signature to reduce its detectability sensitivity to mines, submarines, and other detection systems is called magnetic stealth. In deep waters, a ship's magnetic signature could be reduced to levels undetectable to undersea mines, thereby obviating the need to hunt or clear these mines during the initial time-critical and resource-demanding phase of a conflict. In shallow waters, reducing magnetic signatures can improve mine clearance efficiency, reduce the effective density of minefields, reduce the time and platform resources required to clear minefields, and reduce the risk of mine strikes for subsequent ships sailing. [0003] Currently, the Navy's area of interest has shifted from the deep sea to the coast. The acoustica...
