Novel M-Sequence UWB Sensor for Ground Penetrating Radar Application

The article gives a brief overview of the ongoing research in the field of the ultra wideband (UWB) front-end circuits for ground penetrating radars (GPRs). The novel concept for GPR front-end circuits exploiting electrically short active antenna is considered. The designed low cost active antenna achieves the wide frequency band of the radar system and minimal dimensions. In the paper, measurement results with designed circuits for the active dipole UWB antenna are presented. The circuits offer enhanced user experience in comparison to currently used conventional GPR systems.
