Optimization of Short-Pulse GPR Transmit Antenna

摘要

By analyzing the current distribution of Bow-Tie antenna used in short-pulse ground penetrating radar, the methods of antenna load and driving are presented in this paper to reduce strength of reflective wave both at antenna end and excitation point.The numerical simulation results show the strength of reflective wave is smaller than - 55 dB comparing with the driving wave when the methods are adopted.
