Abstract :
An advanced UWB impulse surface penetrating radar (SPR) system-RadarEye is introduced in This work. It provides high resolution pavement thickness estimation and subsurface objects imaging for civil structures inspection. Super resolution time delay estimation algorithm based on wavelet transform and TAM-BP imaging algorithm are presented with high accuracy on layer thickness estimation and high spatial resolution on subsurface imaging. Both indoor and outdoor experiments show the feasibility of this system.
