Abstract
A method is proposed to reduce the influence of external noise magnetic field on the accuracy of estimating current dipole parameters. It utilizes the spatial correlation of external noises, and is applied to data measured using a multichannel magnetometer. Computer simulation clearly demonstrates the effectiveness of the proposed method.Keywords
