Underwater buried target location method based on low signal-to-noise ratio magnetic field signal detection
Yong Yang, Li Yi, Wen Wudi, Zhongle Liu · 2024
In the process of underwater buried target detection, the underwater buried target is replaced by a magnetic dipole model. In view of the low signal-to-noise ratio of the target signal, the orthogonal basis decomposition detection algorithm is used to greatly improve the SNR ratio of the magnetic target signal in water and effectively detect the magnetic target. A cruciform detection method is used to determine the location of the magnetic target. The simulation results show that this method has certain engineering application value.
