TWO DIMENTION HIGH-RESOLUTION EARTH RESISTIVITY SURVEY FOR DETECTING UNDERGROURD CAVES

The high-resolution earth resistivity survey study mainly deals with detectal undergrourd caves, such as artifical caves or nature caves et al.. The pole-dipole electrode array is used in acquisition of the field data along the continuous two-dimention profile. The data are procssed by means of the target anomaly matched filtering technique and the across mapping method to show the underground anomalous resistivity bodies.
