采用探地雷达探测，在隧洞中布置交叉测网或某些特殊情况下必需沿隧洞断面作环形探测时，测线为首尾相接的圆。平面构造和球状地质构造在圆形测线的雷达图像中均表现为弧状同相轴。通过圆形测线与探测对象的空间几何关系，导出其反射信号的关系式，并开发出解释软件，可精确计算探测对象的几何参数。

GPR profile is designed to the crossed grid in the tunnel, and in some special circumstances required along the tunnel cross section for the circular detection,The profile is a circle connected by start and end. Plane and spherical geologic structureare character?ized by arc shape in the radar images . Based on space geometry relation of the circular line and detecting object, the relation formula of the reflected signal is derived and developed software, and the precise detection of geometric parameters of the object can be ob?tained.
