Abstract
<p>Two-electrode straight open magnetic source (TSOMS) has been widely used on the magnetic minesweeper and magnetic decoy. Fast-forward modeling and obtaining the high-precision magnetic field in the air are the prerequisites for real-time inversion and positioning of the TSOMS. In this paper, we propose an algorithm to calculate the magnetic field of the two-electrode straight open magnetic source (MFTSOMS) by previous theoretical research. And a classical algorithm of electric dipole magnetic field is used to verify the correctness of our algorithm. Considering the relationship between the accuracy and efficiency of the calculation, the optimized number of subdivision units of n = 105 is determined. In this case, the time range of calculating one point is from 0.01 to 0.2 seconds, and the order of magnitude of the calculation accuracy is about 10-6. Furthermore, a scaling experiment has been performed, and the results show a great agreement with the simulation under the optimized number of subdivision units. Index Terms—Magnetic Field of the Two-electrode Straight Open Magnetic Source (MFTSOMS), calculation accuracy, calculation efficiency, scaling experiment.</p>
