摘要
The AMT method is used widely in metal mining and groundwater as well as environmental engineering survey.According to AMT signal characteristics and on the basis of previous research results,the authors developed AMT signal recorder independently by relying on the existing AMT magnetic sensors and electrodes.This paper described the recorder related to the key technologies of hardware and software,and made a comparison with similar instruments abroad through field test.The results show that the indices of the independently-designed ATM instrument can meet the standard AMT instrument measurement requirements basically.
