摘要：
The pure secondary field features of transient electromagnetic (TEM) method have its observed data have similar shapes for different geo-electrical models so that I-D fitting inversion results in time-domain are not as good as results in frequency-domain. In this paper, developing I-D time-domain signals to 2-D time-frequency (T-F) plane and using minimum structure inversion algorithm, we realize joint T-F inversion. It is shown that T-F inversion is provided with higher adaptability and the inversion results are much improved by means of it.
