Comparison of FMCW and pulse type groundpenetrating radar(GPR) for water leakage detection

Two types of GPR system(FMCW and pulse) were made for water leakage detection with bandwidth of 100MHz ~ 400MHz. The outdoor test site was constructed to acquire the radar signal of water leakage. Water leakage situation was also implemented. Those feasibility for water leakage detection is analyzed by the comparison of the measured data using two GPR systems. And the detection algorithm of water leakage is also proposed. Keywords-component; Ground-penetrating radar(GPR); FMCW; pulse radar; UWB; water leakage
