摘要： 随着磁传感器技术及磁测技术的发展，通过测量磁梯度张量进行磁探测及磁定位已成为磁探领域的新方法。但在磁梯度张量测量过程中，由于机械安装的误差导致的磁传感器阵列中各传感器的磁轴的不平行将会极大的降低磁定位的精度。本文提出了一种易于实现的磁传感器阵列非平行度测量方法——相位差法，并通过试验验证了其有效性。

Abstract: With the development of magnetic sensor technology and magnetic detection technology, magnetic gradient tensor measurements have become a new method in magnetic detection field. However, magnetic sensors in the detection array always have non-parallelism, thus reducing the magnetic positioning accuracy. A simple and convenient method called phase-difference algorithm is presented for measuring the non-parallelism of the sensors. Testing results indicates the validity of the method.
