GEOPHYSICAL SURVEY TRANSPORTED SYSTEM OF IMPULSIVE ELECTROMAGNETIC TYPE, SYSTEM FABRICATION PROCESS AND CORRESPONDING DETECTION METHODS

摘要

The geophysical survey transported system of TDEM type includes at least one inductor element emitting of a primary magnetic field induced during the measurement period and at least one receiver element receiving the secondary magnetic field generated in return by the ground exposed to the primary field induced during the measurement period. The receiver element of the system is only slightly sensitive to the primary field induced. A fabrication processes of such system and a mining and/or environmental detection method using such system are also disclosed. The system can be hung under, in front or above a vehicle, to realize efficient geophysical measurements.
