Reconfigurability of the integration time in stepped frequency GPR systems

In this paper, we propose some results regarding the possibility to reconfigure the integration time of each harmonic tone of a stepped frequency GPR system in a programmable way. It will be shown that this can allow the rejection of undesired narrow band interferences on the received signal without needing to filter the signal (which can degrade the achievable resolution), and with only a slight increasing of the time required to perform the measure. This is made possible by a reconfigurable system, as it will be shown.
