Impulse Ground Penetrating Radar Hardware System Design

Hardware design methods for impulse ground penetrating radar (GPR) are presented. The designed impulse GPR system mainly consists of ultra wideband (UWB) transmitting and receiving antennas, impulse generator, sampling down converter, time varying gain amplifier, timing and synchronization controller, high accuracy digitizer, and so on. All these modules were designed and realized. The GPR system can operate from 100 to 1000 MHz to obtain different detecting depth and precision. An experimental GPR system had been completed and field test proved this design was successful
