在物探资料的处理和推断解释中,常常遇到在测量误差和地质噪声的干扰背景上划分有用异常的问题.测量的偶然误差和局部地质一地形不均匀体形成的干扰,通常具有随机性质,而有用异常则一般具有某些统计的规律性.因此,可用信息论中的某些理论和方法,来解决在随机干扰背景上划分有用物探异常的问题. 物探所遇到的随机干扰,一般具有以下性质:
In geophysical data processing and inferential interpretation, it is often encountered the problem of delineating useful anomalies on the interference background of measurement errors and geo-noise.The accidental errors of measurement and the interference caused by inhomogeneous local topography-geography usually have random properties, However, some useful anomalies generally have some regularity of statistics, so some theories and methods in information theory can be used to solve the problem of dividing useful geophysical anomalies on the background of random disturbances.The random disturbances encountered by geophysical prospecting generally have the following nature:
