本发明涉及一种重磁场各阶梯度张量场测平面探测数据质量的统一评价方法，包括地球势场各阶梯度张量场测平面探测数据的张量表达；基于希尔伯特变换的张量场数据综合质量定性评价；通过建立相对误差张量与相对差异度张量之间对应关系的机理或回归模型，评估数据的准确性。本发明评价方法对于重力场和磁场的各阶梯度张量场测平面探测数据，都可以根据形成其对应的质量评价方法，具有广泛的适用性；质量评价方法综合考虑了测平面探测数据的空间位置关系和各阶梯度张量多分量的特点，能够评价探测数据的整体质量，同时也无需外部数据作为参考；在需要同时用到重力和磁场数据的应用下，评价方法能够为二者的数据质量提供一个统一的参考标准。 The invention relates to a unified evaluation method for the quality of plane detection data measured by each gradient tensor field of a gravity magnetic field. The method comprises the following steps: performing tensor expression on the plane detection data measured by each gradient tensor field of an earth potential field; performing tensor field data comprehensive quality qualitative evaluation based on Hilbert transform; and evaluating the accuracy of the data by establishing a mechanism or a regression model of a corresponding relationship between the relative error tensor and the relative difference tensor. According to the evaluation method disclosed by the invention, the corresponding quality evaluation method
