结果表明：应用该文所介绍的处理方法不但能有效压制探地雷达信号中的随机干扰而且能精确确定反射波的起跳点。
The results demonstrate the cross correlation filter not only can suppress random noise in GPR signal but also confirm exactly the onset of reflection wave.
探地雷达系统一般采用超宽带短脉冲信号，因而其天线系统必须具有较好的宽带性能。
The ground penetrating radar (GPR) systems usually use broadband electromagnetic pulse, so the antennas must be wideband and can couple electromagnetic energy into the ground.
