Realization of ground-penetrating radar migration imaging in frequency-wavenumber domain

In recent years, with the rapid development of electronic technology, ground-penetrating radar in engineering geological exploration, archeology, non-destructive testing of building structures, hydro-geological surveys, environmental surveys, mineral exploration, military and other fields has achieved a very wide range of applications. China's ground-penetrating radar equipment was mainly imported, but foreign equipment's supporting ground-penetrating radar data processing software is very simple, only roughly imaging the two-dimensional data collected by ground-penetrating radar, not conducive to making the advantages of high-resolution detection of ground-penetrating radar to complete the weak anomalous signal extraction and to explain more sophisticated underground structures. This paper conducts a secondary research on two-dimensional data collected 16/ground-penetrating radar, suppresses the background noise, applies migration theory in frequency-wavenumber domain to ground-penetrating radar imaging and discusses the selection and calculation methods of the migration's main parameters, achieving a significant effect on the measured data's processing and interpretation and promoting the ground-penetrating radar data-processing on the development of post-processing.
