    • The object of the present invention is to realize a low-invasive underground exploration apparatus, system, and method which are capable of specifying the kind, three-dimensional position, and amount of a substance present in the ground. The underground exploration apparatus, system, and method includes: measuring, at multiple points, a high frequency voltage that appears upon conduction of high frequency current through the ground to obtain measurement results at two or more frequency levels; employing an ground model using the finite element method, the boundary element method, an impedance network, or the like to estimate a substance in the ground by changing unknown quantities of the ground model such as local dielectric constant and electric conductivity so as to make an error between the actual measured value and the calculated value smaller; and displaying input information of the ground model and results of the estimation processing two-dimensionally or three-dimensionally.
    • 本发明的目的是实现能够指定存在于地面中的物质的种类,三维位置和量的低侵入式地下勘探装置,系统和方法。 地下探测装置,系统和方法包括:在多个点测量在通过地面传导高频电流时出现的高频电压,以获得两个或多个频率水平的测量结果; 采用有限元法,边界元法,阻抗网络等的地面模型,通过改变诸如局部介电常数和电导率的地面模型的未知量来估计地面中的物质,从​​而使 实际测量值与计算值之间的误差较小; 并且二维或三维地显示地面模型的输入信息和估计处理的结果。
