| 摘 要： | 以往提及异常分离只是简单滤波,分离出相对高频和相对低频的两种异常,或者使用高频分析局部异常,或者使用低频分析区域异常。在分析局部异常时,由于对异常规模的更多关注,分离出来的频率也是一种"相对的高频"——实际是中等频率。笔者从成图角度分析了异常分离的重要性,并引用了实际工作的资料,展示了异常分离对成图、信息提取的良好作用和效果。

| Abstract: | The anomaly separation mentioned in the past refers only to simple filtering,and can only separate two kinds of anomaly: relatively high frequency and relatively low frequency;either the high frequency is used to analyze local anomaly,or the low frequency is used to analyze regional anomaly.When the local anomaly is analyzed,due to the much attention paid to the dimension of the anomaly,the separated frequency is a kind of "relatively high frequency"(actually intermediate frequency).From the angle of mapping,the authors analyzed the importance of anomaly separation and,on the basis of data from practical work,demonstrated the good role played by the anomaly separation in mapping and information extraction. |
