Ground Penetrating Radar Profile Imaging Research Based on Hyperbolic Fitting

Abstract

Firstly, analyzing and researching the change characteristics and rules of measured signals of a ground penetrating radar, and providing a method for realizing joint imaging of reflection and scattering signals by applying a diffraction scanning migration superposition method based on the principle of Huygens 'first Fresnel zone'.  And then according to a hyperbolic arc distribution rule generated by the scattering signals, providing a hyperbolic fitting algorithm to perform joint imaging on the ground penetrating radar measurement profile. Finally, the application example shows that the joint imaging can be suitable for various complex geological conditions, the imaging result can reflect the distribution form and position of the abnormal body more accurately and obviously, and the working efficiency and the achievement precision are effectively improved.
