在手持式探地雷达(GPR)探雷传感器探雷中，探地雷达信号受到天线与粗糙地面距离不稳定的影响。本文提出了一种补偿探地雷达中地面反射到达时间不规则性的方法，并将其应用于柬埔寨雷场采集的数据集。选择地面反射功率最大的频率，对该频率处接收信号的相位进行均衡，以补偿不规则反射。证明了地面反射信号变得均匀，证实了目标的形状质量可以得到改善。
In landmine detection by a hand-held ground penetrating radar (GPR) sensor, GPR signal is suffered from the unstable stand-off distance between the antenna and the rough ground surface. We propose in this letter a method to compensate the irregularity in the arrival time of the ground reflection in GPR and applied it to data sets acquired in minefields in Cambodia. Selecting the frequency with the highest power of the ground surface reflection, the phase of the received signal at the frequency is equalized to compensate the irregular reflection. We demonstrate that the ground reflection signal became uniform and confirmed the quality of the shape of the target can be improved.
