Magnetic Moments Estimation Method of a Magnetic Object Based on Neural Network

In localization of magnetic objects, a magnetic moments estimation method is proposed based on neural network. Firstly, a mathematical model is founded to estimate magnetic moments by minimizing the least-squares error at the observation points. Secondly, Hopfield neural network is used to solve the above optimization model and a self-adaptive correction algorithm is taken to improve the robustness of the model. Finally, a numerical experiment is designed to verify the effectiveness of the proposed method. The results show that the practicable method has many advantages such as high accuracy, good robustness, and easy implement.
