摘　　要：针对传统磁传感器精度不高和无法充分利用z轴磁场信息的不足,提出基于三点公式的直角四面体模型。该模型借鉴三点公式中的端点公式和中点公式,对直角四面体结构进行重新设计并提出相应模型的磁梯度张量计算方法。在与平面中效果最好的十字形传感器进行对比时,得出基于中点公式的直角四面体模型更好的结论。根据磁场的衰减规律,利用免疫克隆算法对新模型进行优化设计,使优化后的传感器模型的精度更高。仿真结果表明,该模型能充分利用磁场的三轴信息,能够有效提高磁梯度张量的测量精度。In view of the low precision of traditional magnetic sensor and the inability to make full use of the z-axis magnetic field information,a right-angle tetkic model based on the three-point formula was proposed.the model drawed on the endpoint formula and midpoint formula to redesign the right-angle tetrahedral structure and proposed the magnetic gradient tensor of the corresponding model.In contrast with the best effective cruciform sensor in the plane,the midpoint formula yielded better conclusions for the right-angle tetrahedral model.according to the attenuation law of the magnetic field,the new model was optimized to design using the immunocloning algorithm to improve the accuracy of the optimized sensor model.Simulation results showed that the proposed model could make full use of the triaxial information of the magnetic field and improved the measurement accuracy of the magnetic gradient tensor.
