摘　　要：从二维滤波的原理出发 ,利用探地雷达图像中干扰信号和有效信号频波谱分布的差异 ,通过对探地雷达实测资料进行二维滤波 ,说明二维滤波对消除探地雷达图像中的特殊干扰波 (如空中绕射、旁侧反射等视速度与有效信号存在较大差别的干扰波 )有良好效果。Based on the principle of two dimension filtering and on the distribution difference of f-k spectra between interference signals and usable signals, it is shown that two dimension filtering can effectively remove interference waves (such as diffracted waves from air or side whose apparent velocities are different from those of usable reflections) from the image of GPR profile.
