摘要
采用最小二乘法计算张量阻抗要素时,可以利用各种计算结果之间的差异来衡量噪声影响的程度,而全信息矢量相干度正是基于这种思想提出来的,用以评价数据质量。以庐枞矿集区MT数据为例,通过对部份具有典型特征的数据进行质量评价,并与常见的数据质量评价方法进行对比,验证了全信息矢量相干度在MT数据质量评价中的作用,并分析了各种评价方法的应用效果,为MT数据的进一步处理提供了有力的保证。
The difference of calculation results can be used to measure the degree of noise when using least square method to calculate the tensor impedance elements,Vector coherence is based on this idea to evaluate data quality.One case study in Lujiang-zongyang ore concentrated area,through evaluate data quality of survey station with typical characteristics,and compare with common data quality evaluation methods,verified the function of vector coherence in MT data quality evaluation,analyzed the effect of these methods,to provide a powerful guarantee for further MT data processing.
