The authors investigated a novel method for it. Using three coils with DC current to excite magnetic field and one triaxial magnetoresistive sensor to measure the excited magnetic vectors, they tried to solve the problem. The authors provided the localization principle of the method and analyzed it by an experiment, too. The method may be applied in practice in the future though it is still immature now.展开更多
