We describe a new approach for modelling airborne transient electromagnetic (TEM) data which combines the use of on- and off-time data for inversion. Specifically, the response is modelled using system response convolution both during and after trans

Summary Data from surveys using the transient electromagnetic method (TEM) are inevitably corrupted by random noise. This noise, originating from both man-made and natural sources, is a limiting factor in the interpretation of the data. Radio signals
