Based on wavelet multi-resolution 3-D GPR migration
Standard form in multi-resolution decomposition theory has been introduced in details;the essence of two-dimension radar data carry on first level or multilevel wavelet multi-resolution decomposition has been elaborated.It laid a theory foundation for multi-resolution of wavelets 3D migration algorithm.Then,making use of the bursting reflection theory and floating coordinate transform,we can deduce the finite difference format of GPR three-dimension wave equation.Solving the extrapolate matrix of wave field in the wavelets domain,it could also get the migration algorithm of GPR three-dimension wave equation in wavelets domain and migration processing program,and puts this program to three-dimension radar forward section.Through comparing the radar data before and after the migration processing,it is known this three-dimension migration algorithm could make the reflection wave return to original position,and make the diffraction wave converge in the three-dimension sections.The lateral resolution of radar sections could be highly enhanced.
