摘　　要：大深度多功能电磁探测系统,主要由多功能电磁探测仪器、数据采集与处理、电磁二三维正反演模拟等组成。系统研发中,攻克了多功能电磁分布式接收、大功率发射、三分量高温超导磁传感器所涉及的多项关键技术,并研究开发了配套的数据采集、处理与解释技术,系统具备AMT/MT、CSAMT、IP等测量功能。对研发系统进行了与GDP-32Ⅱ的野外对比试验及典型矿区的应用,取得显著的试验应用效果。The large - depth, multi - function electromagnetic survey system is composed of the multi - function electromagnetic detection equipment, the techniques for data acquisition and processing and the software for electromagnetic two or three dimensional positive inversion simulation. Based on a study of its corresponding key technologies, a distributed multi -function receiver prototype is developed. Accordingly, the high -power multi -function intelligent transmitting prototype and the three component high temperature superconducting magnetic sensor are also designed and developed. As a result, the matched data acquisition, processing, and interpreting technology of the multi - function electromagnetic system have been successfully resolved. The system has the measurement function of AMT, MT, CSAMT and IP. A number of good results have achieved in comparative trail between the self - developed system and the GDP - 32 ^Ⅱ system, and the application of typical mine areas.
