摘　　要：高分辨地电阻率系统主要用于地下洞体（老窑采空、岩溶等人工或天然洞穴）探测。采用单极－偶极连续二维剖面观测，对采集的资料应用目标异常匹配滤波法或交汇法再现地下异常体形象．he high-resolution earth resistivity survey study mainly deals with detectal undergrourdcaves, such as artifical caves or nature caves et al.. The pole-dipole electrode array is used in acquisition ofthe field data along the continuous two-dimention profile. The data are procssed by means of the targetanomaly matched filtering technique and the across mapping method to show the underground anomalousresistivity bodies.
