Novel tomographic based approach and processing strategies for GPR measurements using multifrequency antennas

This work is focused on an advanced processing strategy based on the microwave tomography and novel approaches able to exploit the data-diversity ensured by the exploitation of antennas at different frequencies for Ground Penetrating Radar (GPR) prospecting. The aim is to improve the interpretability of the reconstructed images compared to the standard data processing and the interpretation of vertical profiles and time-slices. The effectiveness of the proposed strategies will be shown for a synthetic example and a realistic GPR survey performed with 200 and 600 MHz antennas for archaeological prospecting in Palatino site (Rome) having the aim of detecting buried objects within the first two meters of the subsurface.
