A novel broad bandwidth dual-polarization GPR antenna was also developed for collecting fully polarimetric data over a wide frequency range (20 MHz-800 MHz). This new design was improved from its single-polarization version, dielectric-loaded horn-fed bow-tie (HFB) antenna, introduced by Chen (1997). The new design features improved stability and directivity over conventional surface-based GPR antennas. Such antenna is currently applied to discriminate buried UXOs from other false alarm reduction.
