层析成像在巷道无线电波透视法中的应用

针对巷道无线电波透视法实测数据不完整和反演方程组欠定这一问题，利用层析成像方法，重建了地质异常体图像．层析成像算法根据数据量大小、品质来选择矩阵反演法与迭代重建法，然后对物理模型、实测资料进行层析成像处理，结果获得满意的重建异常体图像．层析成像具有稳定性好、抗干扰能力强、分辨力高等特点，且异常体的性质也有反映，说明该方法在巷道无线电波透视中是可行的．

Application of Tomography in Radio Wave Tunnels Perspective

Aiming at the problem that the actually measured data for radio wave tunnels perspective method are not full and the inverse equation groups are undetermined, the image of geologic abnormal body was reconstructed by using tomography method. For this method, the matrix inversion and iterative reconstruction are selected based on the quantity and quality of data, and then the physical model and the actually measured data are processed by using this method. The result shows that the reconstructed geologic abnormal body image is satisfactory for it is good in stability and anti-jamming and has a high resolution, and the feature of abnormal body can also be reflected, indicating that this method is feasible to be used in radio wave perspective method in tunnels.
