Abstract

Abstract

The accurate modeling of the radiated magnetic field of underwater targets is of great significance to the development of magnetic detection technology. The target radiation magnetic field mainly consists of magnetic anomaly field and wake magnetic field, while the magnetic sensor usually receives the total magnetic field signal during detection. Current research mainly focuses on the simulation analysis of magnetic anomaly fields and wake magnetic fields respectively, lacking systematic studies on the radiation mechanism, propagation model, spatiotemporal characteristics and attenuation laws after their integration. This makes it difficult to effectively promote the development of underwater target magnetic detection technology. To this end, this paper proposes a method for analyzing the spatiotemporal characteristics of the comprehensive magnetic field of underwater targets. COMSOL and MATLAB software are used to model and study the magnetic anomaly field and wake magnetic field respectively. By integrating the two magnetic field models through vector superposition, the spatiotemporal characteristics and attenuation laws of the target's radiated magnetic field are comprehensively analyzed, which improves the solution efficiency and model accuracy of the comprehensive magnetic field. At the same time, it reveals the specific influence law of the target motion parameters on the comprehensive magnetic field, providing theoretical support for the high-precision modeling of underwater target magnetic detection.
