- Abstract:
-
The basic principle of electromagnetic wave propagation of pavement radar in pavement structure is introduced, combined with the time-domain finite difference method algorithm, the one-dimensional FDTD equation, the effective parameters of the soft excitation source, the effective parameters of the hierarchical interface, and the important influence of absorption boundary conditions in the application simulation process are analyzed, and the forward evolution model of air-coupled pavement radar is established. Theoretical simulation and practical engineering numerical examples show that the model is feasible for road radar forward simulation, and the error does not exceed 2%.
