Abstract：Based on the expression of ground layered media on the surface magnetic dipole field derived by A. A. Kaufman, the authors deduced frequency-domain airborne electromagnetic field's expression for magnetic dipole source. Using two-layer and three-layer typical earth model, the authors studied electromagnetic response at different flying heights. Calculations show that the changes of the flying height affect directly the electromagnetic response's value of points measured.
