High-Resolution Ultra-Wideband Material Penetrating Radar (UWB-MPR) using Modified Configuration of Receiver Antennas

摘要

In this paper, in order to implement the see through the wall and ground penetrating radars using vector network analyzer at the first step we present a modified UWB Tapered Slot Antenna (TSA) and Wilkinson power combiner. In the following the main purpose of this paper is employing a new technique using modified UWB antennas and power combiner to improve the reflected signal of localizing underground metal for 1D visualization of material penetrating radar results. In the last section two scenarios of GPR profiles with a single receiver antenna and dual receiver antennas over ground surface with buried metal target are presented to validate the accuracy of the proposed approach. This signal collecting technique collect more energy form reflected signals in contrast with conventional MPR. Hence, stronger reflection is available to achieve higher chance for target localization.
