Abstract

In this paper, the time domain modeling of an indoor impulse UWB GPR systems, built in the scope of the HUDEM project, is presented. For an impulse UWB system, a time-domain modeling is an obvious choice. We explain how the antennas can be characterized by their normalized impulse response. By considering the antenna as a convolution operator, we get a mechanism for modeling the whole radar system as a cascade of linear response, which gives a lot of advantages and possible application. In our research it is used to express the radar range equation in the time-domain, to optimize the antenna configuration and to calculate the point-spread function of the UWB GPR at a given depth. The point-spread function can be used for migration by deconvolving it from the collected data. In this way the migration method takes into account the characteristics of the radar system. Finally, results of this migration method on data obtained by our UWB GPR system are shown.
