This paper deals with different processing techniques applied to step-frequency penetrating radar data gathered by a novel step-frequency penetrating radar in a measurement survey of the walls of the historical room “Salone dei 500” in Palazzo Vecchio (Firenze, Italy). The aim of the investigation was to detect discontinuities in the masonry walls, possibly corresponding to a cavity containing fragments of the lost fresco of the ‘Battle of Anghiari’ by Leonardo da Vinci. Data have been processed by means of two different techniques. The first one exploits a two dimensional synthetic aperture focusing, while the second one is based on a one-dimensional inverse scattering approach. Both techniques reveal the presence of a discontinuity in the eastern wall of the room at a depth between 10 and 20 cm, whereas no discontinuity traces are observed on the other walls.

Abstract
This paper deals with different processing techniques applied to step-frequency penetrating radar data gathered by a novel step-frequency penetrating radar in a measurement survey of the walls of the historical room “Salone dei 500” in Palazzo Vecchio (Firenze, Italy). The aim of the investigation was to detect discontinuities in the masonry walls, possibly corresponding to a cavity containing fragments of the lost fresco of the ‘Battle of Anghiari’ by Leonardo da Vinci. Data have been processed by means of two different techniques. The first one exploits a two dimensional synthetic aperture focusing, while the second one is based on a one-dimensional inverse scattering approach. Both techniques reveal the presence of a discontinuity in the eastern wall of the room at a depth between 10 and 20 cm, whereas no discontinuity traces are observed on the other walls.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
