Abstract: The embodiment of the invention provides a ground-air TEM transverse magnetic polarization field detection method and system, and a forward modeling method and device. The ground-air TEM transverse magnetic polarization field detection method comprises: adopting an umbrella-shaped source as a ground emission source, wherein the umbrella-shaped source is an emission source device comprising a plurality of emission line sources, the lengths of the emission line sources are the same, one end of each emission line source is connected to the center of the umbrella-shaped source, the emission line sources are arranged in an umbrella rib mode, current directions diverge outwards from the center along each emission line source, and included angles between adjacent emission line sources are identical; and using the umbrella-shaped source to detect a ground-air transient electromagnetic field, and obtaining the horizontal magnetic field component data of the umbrella-shaped source, thus realizing the observation of a ground-air TEM transverse magnetic polarization field. The above technology of the invention can cover the shortage of a ground-air TEM in high-resistance target detection.
