Based on the electromagnetic theory, the forward formulae and algorithm are obtained for aerial electromagnetic methods (ATEM) with dipole-dipole array in time domain under the condition of stratified earth. The computer program for computing the ATEM response is worked out and the forward computing is completed for some typical geoelectrical sections. The results provide a basis for analyzing the detecting capacity and applied conditions of the ATEM and for designing the ATEM system on the helicopter.
