| 摘 要： | 针对探地雷达的数据干扰问题,讨论了探地雷达接收波的种类和速度参数,确定干扰信息,并分别对电线杆、架空线路、山体等各种干扰体进行了实例分析,利用到达时间和传播速度上的差异,综合运用反褶积、FK滤波、偏移等方法对干扰进行了滤波处理,结果显示多次波、弧形干扰、水平干扰等一系列干扰都被有效滤除,突出了有效波。证明这种滤波思路和方法是可行的,能够为下一步的解释工作打下良好基础。

| Abstract: | In this paper,the receiving wave types and speed parameters of GPR were discussed,the interference information was determined,and the examples of utility poles,overhead lines,mountains and other interference objects were analyzed.According to the differences in arrival time and propagation velocity,filtering processing of the interference was made by means of deconvolution,F-K filtering and shifting.The results show that the multiple wave interference,curved interference and horizontal interference can be e... |
