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-32Ⅱsystem, and the application of typical mine areas.
