3D Forward Modeling Analysis Based on the New Airborne Mobile MT Method
In recent decades,ground geophysical exploration has made significant advances in engineer-ing exploration and development.However,in challenging mountainous terrains,ground geophysical methods often suffer from low efficiency and limitations in survey line design due to topography.Airborne geophysical methods,which collect data from the air,demonstrate distinct advantages under complex ter-rain conditions,offering new solutions for engineering exploration in such areas.Mobile MT,a new natu-ral-source airborne electromagnetic method proposed in international field in recent years,combines mag-netotelluric method with airborne electromagnetic method.It utilizes an airborne platform to measure three-component magnetic fields(Hx,Hy,Hz)while ground-based stations measure horizontal electric fields(Ex,Ey)to infer the earth electrical structure.Given that actual earth models are often 3D earth e-lectrical models,it is essential to conduct 3D forward modeling studies of Mobile MT to explore its re-sponse characteristics to anomalous geological bodies,thereby providing a theoretical foundation for data interpretation in practical applications.
