1. Orlando L., Detection and analysis of LNAPL using the instantaneous amplitude and frequency of ground-penetrating radar data. Geophysical Prospecting, Vol. 50 (1), pp 27-41, 2002.
In paper n. 1 GPR attributes of the complex trace (amplitude, phase, and frequency) are used to detect light non-acqueous phase liquid (LNAPL) in the vdose zone.
2. Orlando L.,. Semiquantitative evaluation of massive rocks quality using ground penetrating radar. Journal of Applied Geophysics, vol. 52, Issue ,1 pp 1-9, 2003.
In paper n. 2 a method based on the analysis of the energy calculated as the square of the sample amplitude of the real trace are proposed to carry out a synthetic map of rock quality.
3. Orlando L. and Slob E., Using multicomponent GPR to Monitor Cracks in a Historical Building. Journal of Applied Geophysics, Vol. 67, 327-334, 2009.
In paper n. 3 multicomponent GPR data are used to detect cracks in a historical building, and to monitor their dynamics over time, caused by a slowly and irregularly moving landslide.
4. Orlando L., Pezone A., Colucci A., Modelling and testing of high frequency GPR data for evaluation of structural deformation. NDT&E International, Vol. 43, 216-230, 2010.
In paper n. 4 a 2 GHz GPR multi-component antenna is applied on a hollow pier for the evaluation of deformation induced by mechanical stress. The GPR data collected before and after the mechanical stress application, in reflection and transillumination modes are analyzed.
5. Orlando L., Detecting steel rods and micro-piles: A case History in a civil engineering application. Journal of Applied Geophysics, vol. 81, pp. 130-138, 2012.
In paper n. 5 key factors and use numerical simulations and real data examples are used for the tradeoff between detection and resolution. The targets were micro-piles and steel bars buried into an ancient wall.
6. Orlando L., Instability analysis of the villa Arianna site at Castellamare di Stabia (Naples). Near Surface Geophysics, Vol. 10, no. 1, pp. 89-100, 2012.
In paper n. 6 advanced processing of the GPR direct ground wave are applied in order to successfully detect and map near-vertical fractures that affect an arcaheological structures located in unstable areas.
