GPR Pulse Propagation Topography [PDF]
Applied Computational Electromagnetics Society, 2021 In this article, I propose a new method for calculating and visualizing the pulse radiation within the depth range commonly used by Ground Penetrating Radar (GPR). The text describes the method and illustrates the propagation with several examples. One conventional method is also applied for a quick comparison.
