Abstract :
Ground penetrating radar (GPR) is a non-destructive and non-intrusive subsurface investigation equipment which has been widely used in the field of civil engineering. Some challenges which GPR encountered for pavement subsurface inspection are: 1)GPR signal are easily corrupted by noise; 2) commercial GPR whose resolution is depended on system bandwidth, is not suitable for ultra-thin thickness estimation. This paper focus on using super-resolution MUSIC algorithm for ultra-thin pavement layer-interface detection and time-delay estimation compared to threshold detector and match filter.The results based on the simulation data under different conditions and measured GPR data are also presented.
