摘要
市区内进行地质雷达勘探,探测剖面往往受到高压电线的严重干扰。介绍在地质雷达剖面上,如何识别和去除高压电线干扰。在干扰识别方面,采用速度扫描动校正方法来实现;在干扰去除方面,采用道间水平预测滤波、相位反相、剖面叠加、小波变换等多种组合算法实现。通过实例应用证明,介绍的方法是可行的,处理效果明显。
To do geology radar exploration in city area, the disturbing signal of high-voltage line is found on radar profile. In this paper, it is introduced how to identify the disturbing signal of high-tension line and how to remove the disturbing of strong high-tension line. The disturbing identifying is realized by dynamic correction; And the removing of disturbing is realized by combination of many algorithms, such as horizontal predicted wave filtering, phase inversing, section superimposing, wavelet transform and so on. These methods are proved to be feasible and the effect of processing is proved to be very good by practical examples.
