摘要 针对脉冲探地雷达回波信号的特性,在传统处理方法的基础上本文提出了一种有效的去除探地雷达中振铃效应的方法,同时引入微波全息成像对实测数据进行合成孔径(SAR)处理,可以看到杂波被明显的抑制,探地雷达成像的距离和方位分辨力都得到很大的改善,从而大大提高了脉冲探地雷达的检测能力。 A effective method of eliminating ringing effect for GPR is given, and microwave holographic imaging is used to carry out synthetic aperture process. The clutter caused by ringing effect is suppressed, and the range resolution and azimuth resolution are improved.
