Application of multi-resolution time domain method in three dimensional forward simulation of ground penetrating radar

摘要：

The author applies the wavelet-Galerkin method to dispersing Maxwell equations.The essay deduces the GPR three-dimension finite difference formula and the numerical stability of DB2-MRTD algorithm.Based on this,the author develops MRTD forward simulation program of GPR which raises the operational speed tremendously and improves 3D GPR forward simulation method.Making use of this self-make program,MRTD processes forward simulation to the 3D triangle metallic body model and gets its 3D fence diagram and slice map of forward simulation synthesize.By analyzing these simulation results,it can deepen the understanding toward 3D radar reflection characteristic,raise the credulity,improve the accuracy of the GPR detection,and also illuminate the validity of MRTD 3D forward simulation method in GPR.
