| 摘 要： | 基于自适应对消和探地雷达信号中的直达波的性质,提出了一种自适应直达波滤除方法,通过对模拟实验数据和实测数据的处理,验证了这一方法的有效性.另外,还给出了其它方法对同样数据的处理结果,通过与这些方法相比较,自适应直达波滤除法是一种运算量少、信号失真小、并可实时处理的方法.

| Abstract: | In this paper,a adaptive interference canceling method is presented to suppress the direct wave in GPR data. By applying this method to measured data of buried object,its validity is demonstrated. Furthermore,computer simulation results show that compared with other methods,the adaptive method is a less signal distortion and can be implemented in real time. |
