THE NUMERICAL SIMULATION AND MIGRATION IMAGING OF GROUND-PENETRATING RADAR BASED ON THE SPLIT-STEP FOURIER METHOD
摘要
Abstract
Based on the basic theory of the electromagnetic field, the authors deduced the wave field extrapolation formula of electric field component in horizontally stratified media. By analyzing the results of numerical simulating and migration imaging using the split-step Fourier method with designed reinforced distribution model and lining thickness model, the authors have reached some conclusions. The split-step Fourier method not only can realize the numerical simulation and migration imaging of two-dimensional non-uniform media, but also has advantages of easy programming and small amounts of calculation. Project real data have tested and verified the ef-fectiveness and practicality of migration imaging using the split-step Fourier method.关键词
