Paper #1 studies in detail the wavelet emitted by two bowtie GPR antennas with nominal frequencies of 800 MHz and 1 GHz. As well, this work presents an attempt to determine, for each antenna, a time zero to correctly assign a position to the reflectors detected.

Paper #2 shows the application of 3D GPR in a forensic case study under taken in a mountainous environment. Main objective is to locate a clandestine grave which is around 10–20 years old and contains human remains of one individual and a metallic tool.

Paper #3 analyzes the viability and effectiveness of GPR in evaluating historical masonry arch bridges. A Roman bridge is surveyed to obtain structural, geometrical, historical and archaeological characteristics.

Paper #4 presents the design and construction of a special trailer designed to evaluate traffic infrastructure with a ground-coupled GPR system. The prototype presented in this work is completely non-metallic, allowing massive data acquisition at a cruising speed up to 80 km/h.

Paper #5 proposes several tests to evaluate the stability of a GPR system working with three different frequencies (500, 800 and 1000 MHz). This type of analysis is especially important in novel systems and antennas to understand their real capabilities and limitations.

Paper #6 provides an example of dense data acquisition over a Roman archaeological site. This work demonstrates how the application of full-resolution GPR imaging can benefit the interpretation of GPR data when compared to pseudo-3D strategies.

Paper #7 extends the purpose of paper n.3 in terms of identifying different GPR signal responses for each structural feature. To assist in the interpretation, the expected electromagnetic wave response is simulated through the use of FDTD modelling tools.
