Abstract
In this work the sensitivity/resolution to the properties of a resistive layer in the horizontal source-receiver configuration is compared to that of a vertical source-receiver time domain method. The question of sensitivity of the methods in a 1D layered model is addressed from an analytical stand point, i.e. by analyzing the close form solutions of the guided mode dominating the far offset and that of the image terms describing the solution at close offsets. It is found that the spatial distribution of the guided mode and its high frequency behavior appears to have more resolution to the target than that provided by the spectral behavior of the image terms.
