摘要
文章给出了瞬变电磁法野外勘探中由感应电压求取感应磁场的方法 ,与理论计算结果的对比说明了方法的可行性。应用该法对实际资料进行了处理解释 ,它表明感应磁场提高了数据的信噪比 。
this paper put forward a method that converts transient induced voltages into induced magnetic fields in TEM field survey,and Compared with theoretical results showing its feasibility Processing and interpreting of field datas using this method account for the merit, which improved data's signal-to-noise ratio(SNR)and make interpreted depth of apparent resistivity more exact
