The northern region of the Maltese archipelago is experiencing lateral spreading landslide
processes. This region is characterized by cliffs with a hard coralline limestone outcropping …

The problem of detecting and localizing 2-D thin scatterers (ie, elongated scatterers whose
cross sections are small in terms of the probing wavelength) from scattered field …

Internal decays in trees can rapidly escalate into a full decomposition of the inner structural
layer, ie, the “heartwood” layer, due to the action of aggressive diseases and fungal …

Velocity estimation is one of the most crucial tasks in ground-penetrating radar (GPR)
surveys. It is an integral part of GPR data analysis for interpreting GPR-generated images of …

According to the Federal Highway Administration, more than a quarter of the bridge decks in
the United States are obsolete or deficient and most of them are made of reinforced concrete …

This paper deals with the shape of the GPR diffraction curve in dependence of the distance
of the measurement line from to the air/soil interface. It will be shown that the diffraction …

This paper deals with the combined use of non-invasive technologies for a reliable and
ready measures of soil physical parameters. In particular, time domain reflectometry (TDR) …

This paper is focused on the measurement of both dielectric and magnetic characteristics of
a penetrable material at radio frequency through a time‐domain reflectometry probe. The …

In this paper, we propose the combination of different migration results achieved on the
same data in order to account for different values of the propagation velocities of the …

The guest editors introduce the papers in the special section, which represent a wide range
of surface and borehole GPR applications, including GPR sensitivity to contaminant plumes …
