便携式等值反磁通瞬变电磁系统及试验应用
Portable opposing-coils transient electromagnetic system and its application tests
摘要
Abstract
In shallow engineering investigations,the small-loop transient electromagnetic(TEM)system is challenged by limitations such as overweight equipment,significant transmitter-receiver mutual inductance,and high manpower requirements.Hence,this study introduced an improved system.Based on the opposing-coils transient electromagnetic(OCTEM)theory,this study calculated the mag-netic field distribution of the generalized opposing-coils antenna device.Furthermore,it designed and developed efficient portable an-tennas and the supporting system(collectively referred to as the portable OCTEM system).Subsequent field experiments demonstrate that while ensuring exploration accuracy,the portable OCTEM system can enhance the investigation efficiency by effectively mitigating the transmitter-receiver mutual inductance and significantly reducing manpower requirements.This study preliminarily verifies the feasi-bility of the portable OCTEM system,providing a novel technology route for developing downsized shallow exploration equipment.关键词
