TIME DOMAIN ELECTROMAGNETIC RESPONSE ABOVE THE SURFACE OF A HOMOGENEOUS EARTH

Piao Hua-rong Sha Shu-qin Wang Yan-liang (Changchun Geological Institute)  
This paper describes the time-domain electromagnetic response above the surface of a homogeneous earth for the application of the impulse type airborne electromagnetic method. The formulations of the response are developed from the those of the frequence-domain by the Fourier transform. Both the horizontal and the vertical component of the secondary field were computed with the parameters of the home-made impulse type airborne electromagnetic system. According to the computer results of the time-domain, the diagrames of interpretation are presented in this paper. It can be used to solve two major problems. The first is to interpret the time-domain airborne electromagnetic data measured at different flying altitude so that the earth resistivity will be provided. The second is to estimate the time-domain airborne E. M. response, if the earth resistivity is given; therefore the pseudo-anomalies caused by the change of the flying altitude will be corrected.
