Pavement Inspection and Characterization Using a Constant Offset Sliding Bistatic GB-SAR System and High-Resolution Imaging Techniques

This paper introduces a novel approach in pavement inspection by applying high-resolution imaging techniques onto a Constant Offset Sliding Bistatic Ground-Based Synthetic Aperture Radar system operated in forward-scattering mode. The performance of this configuration, known for its minimal complexity, is significantly improved by incorporating the spectral analysis method. The integration enhances vertical discrimination and proves effective in complex scenarios with fewer actual sources than anticipated. This approach represents a alternative solution in non-destructive road infrastructure analysis, offering a powerful tool for precise pavement condition monitoring.
