滑动平均法窗口尺度选择研究

Window scale selection by moving average method

文章旨在研究利用滑动平均法分离叠加重力异常时窗口尺度选择的一般规律。给出了球体的重力异常计算公式,绘制出当单一参量发生变化时对应的球体平面重力异常图,对每一幅图进行了滑动平均处理,通过对比不同窗口尺度的计算结果,从中总结出当单一参量发生变化时窗口尺度选择的一般规律。

The purpose of this paper is to study the general rules of window scale selection when separate the superimposed gravity anomalies by using the moving average method.The calculation formula of sphere gravity anomaly was used to illustrate the gravity anomaly map of the corresponding sphere plane when single parameter changed,and all the pictures were processed by the moving average method.The general rules of window scale selection were summed up when a single parameter change by comparing the results of different window scale.
