| 摘 要： | 分辨率是利用探地雷达资料识别浅层地质特征的关键要素。然而,由于子波带宽的限制及子波鸣振而引起子波之间的相互干涉、因而会导致所采集到的雷达记录变得模糊,限制了雷达记录的分辨率。利用反褶积方法可以压制子波的干扰,改善分辨率,本文讨论的是确定性反褶积的方法,在野外空旷地带,将探地雷达的发射天线和接收天线正对,采集两天线间的空气直达波作为雷达的确定性子波。对一个实测探地雷达剖面进行了处理,初步结果表明,该处理方法对雷达剖面资料的分辨率有较好的改善。

| Abstract: | Resolution is a key to confidently identifying unique geologic features with ground-penetrating radar (GPR) data. Source wavelet "ringing" (related to bandwidth) in a GPR section limits resolution because of wavelet interference, and can smear reflections in time and/or space. Deconvolution offers the ability to compress the source wavelet and improve temporal resolution. Source wavelets generated in, transmitted through and acquired from air allow successful application of deterministic approaches to wavelet suppression. A field GPR profiles have been processed in this paper and the tentative results show that determin istic deconvolution processing can improve the resolution of GPR data. |
