- Abstract:
- Ground-penetrating radar (GPR) is often a fundamental tool for cultural heritage preservation. However, under some conditions, coherent noise can occur in the radargram interfering with the useful signal. Reflections from above-surface objects, such as walls or vaults, and buildings, could be recorded in the radar sections and could hide subsurface reflections linked to the structures of interest. The problem of surface scattering can be addressed by using the Discrete Wavelet Transform analysis which decomposes the signal allowing the recognition of different anomalies coming from different targets.
