GPR去除直流分量的问题dewow2 静校正 3 Energy gain---放大深部信号 4 滤波5 扣除背景 6 平均道7 F-K
一直以来都是按照经验来进行DC校正，MALA的文件会推荐一个值直接用于去除直流漂移，一般有 Subtract-mean (dewow) 和subtract-DC-shiftdewow 其具体定义如下The filter acts on each trace independently. With this option activated a running mean value is calculated for each value of each trace. This run...
