摘要
混场源电磁法综合了 MT 和 CSAMT 方法的特点，以天然和人工电磁场相结合为场源，探测介质的电阻率，信号频带为0.01 Hz～100 kHz，探测深度从几 m 到1000 m，主要用于地下水、环境、矿产、工程等探测．本文介绍电磁波发射机、接收机、宽频带磁传感器的研制进展与关键技术．讨论了需要解决的问题．野外实验结果验证了仪器原理样机技术方案的可行性．
Integrating the characteristics of MT and CSAMT with combination source of nature and artificial electro-magnetic field,Hybrid-Source Magneto tellurics(HSMT)detecting method is able to detect the resistivity of thecrust media from several meters to 1000m in depth by the signals of frequency bandwidth 0.001Hz～100kHz.Themethod can be applied in surveying groundwater,environment,mineral resource,engineer and so on.Development ofthis method and the research work on the instruments such as electromagnetic wave transmitter and receiver,wideband magnetic sensor etc.are discussed in this paper.Some problems about the method are also introduced.Field ex-perimental results have proved the feasibility of the technological scheme adopted in the prototype instrument.
