Abstract
If the outputs of flipped AMR sensors are fitted by polynomial regression taking crossfields as the independent variables, anisotropy fields could be calculated by the ratio of zero-order items to second-order items. Test results verified that the anisotropy fields of the x, y, z axial AMR sensor (Honeywell HMR2300) were 0.778 mT, 0.829 mT, 0.820 mT, respectively. They were closed to the designed value (0.8 mT). And the crossfield errors were well compensated utilizing these field constants.
