| 摘 要： | 结合在内蒙古包头地区和上海崇明岛地区的实验站点开展的实验工作,尝试性地提出了探地雷达用于刻画农田土壤剖面层位结构的方法.按照该方法在对探地雷达数据进行处理和分析之后,得到了沿测线的土壤结构细化剖面图,并与开挖剖面对比,结果吻合良好,表明采用探地雷达可以有效地探测土壤层位结构.

| Abstract: | The ground penetrating radar(GPR) can be regarded to some extent as one kind of advanced remote sensing technology applied to the nearing ground surface detection from the point of electromagnetic wave transmission.It can measure changes in the reflection and transmission behavior of electromagnetic wave including magnitude and velocity corresponding to the subsurface features with different dielectric properties.In this paper,a new approach using GPR to estimate soil layered texture is explored.Two research sites in the north and south of China are chosen,and two antenna frequencies(225 MHz and 900 MHz) are specified.The in situ soil sampling and a set of local water table data are utilized for validating the GPR test results.The research results demonstrate the capability of GPR to map the soil layers in depth based on the change behavior of layered soil permittivity. |
