In the context of resonance based radar target recognition, most work is done based on the co-polarized transient target signature excited by linearly polarized excitation. In this paper, the possibility of target recognition based on a cross-polarized wideband transient signature is investigated. Numerical examples of monitoring subsurface target-depth changes demonstrate that the cross-polarized transient target signature can also be applied to these applications. In addition, for the first time, the possibility of applying the E-Pulse technique together with cross-polarized target signature for monitoring geometrical changes of subsurface target is also investigated.
