Torpedo Near-Field Positioning Technique Based on Dynamic Magnetic Measurement and Magnetic Dipole Inversion Model

To enrich torpedo near-field positioning method, a new torpedo near-field positioning technique is proposed based on dynamic magnetic measurement technique(DMMT) and magnetic dipole inversion positioning model, and corresponding measurement system is constructed. The results of onshore test show that this technique can realize accurate location of the moving magnetic source in near field, and the measurement system has high accuracy and stability. This technique may provide a reference for the research of end-trajectory and miss distance measurement in torpedo shooting range construction and relative situation judgment of pass target.
