“…This formal equivalence suggests that processing and interpretation techniques developed for seismic data may be applied to GPR data, usually with minor adjustments. In the last years the application of attribute analysis for different GPR data interpretation has increased, with a continuous implementation of new or optimized algorithms (76)(77)(78). Examples of applications related to archaeology have also been reported (79)(80)(81)(82).…”

An interdisciplinary study of the archaeological landscape of the Trieste area (northeastern Italy), mainly based on airborne light detection and ranging (LiDAR), ground penetrating radar (GPR), and archaeological surveys, has led to the discovery of an early Roman fortification system, composed of a big central camp (San Rocco) flanked by two minor forts. The most ancient archaeological findings, including a Greco–Italic amphora rim produced in Latium or Campania, provide a relative chronology for the first installation of the structures between the end of the third century B.C. and the first decades of the second century B.C. whereas other materials, such as Lamboglia 2 amphorae and a military footwear hobnail (type D of Alesia), indicate that they maintained a strategic role at least up to the mid first century B.C. According to archaeological data and literary sources, the sites were probably established in connection with the Roman conquest of the Istria peninsula in 178–177 B.C. They were in use, perhaps not continuously, at least until the foundation of Tergeste, the ancestor of Trieste, in the mid first century B.C. The San Rocco site, with its exceptional size and imposing fortifications, is the main known Roman evidence of the Trieste area during this phase and could correspond to the location of the first settlement of Tergeste preceding the colony foundation. This hypothesis would also be supported by literary sources that describe it as a phrourion (Strabo, V, 1, 9, C 215), a term used by ancient writers to designate the fortifications of the Roman army

“…For example, it has 171 been observed that as a larger proportion of clay is added to a sandy 172 soil, the central frequency and the bandwidth of the signal reduces 173 and the maximum amplitude of the reflected wave increases [37]. 174 Analysis of the signal frequencies has also been used to locate 175 mineral or hydrocarbon reserves [38], although at frequency 176 ranges lower than those that are usual in pavement studies.

Ground penetrating radar (GPR) is frequently used in pavement assessments, mainly using the evaluation of wave travel times. However, GPR data provide further information that could be used in order to determine the inner conditions and characteristics about materials. In this paper, the possible analysis of the frequency spectrum of GPR signals is analysed and discussed. Several tests were carried out in a portion of a highway in two different stages of its service life. Results highlight the relationship between the shape of the spectrum and the frequency signature with the structure and conditions of the pavement.Preprin

“…Currently, there are over 50 types of seismic attributes used for the interpretation of geological structures, stratigraphy and petrophysical properties of rocks, and interstitial fluids (Chopra & Marfurt, 2005). Many of these attributes have been applied to GPR data directly (Senechal et al, 2000;Corbeanu et al, 2002, among others), or adapted to the specific characteristics of the EM waves propagation (Böniger & Tronicke, 2010;Forte et al, 2012).…”

“…The popularization of this geophysical method through theoretical (Davis & Annan, 1989;Annan, 1996;Roberts & Daniels, 1996), experimental (Redman et al, 1994;Lai et al, 2006) and case studies (Rossetti et al, 2001;De Castro & Castelo Branco, 2003;Forte et al, 2012) has caused a rapid and concomitant progress in the areas of acquisition, processing and interpretation of GPR data. Acquisition techniques has advanced greatly with more efficient generation of the transmitted electromagnetic signal and its digital sampling, improved shielding of the antennas against ambient noise and increased number of available antennas operating on different EM pulses frequencies.…”

“…Incorporation of GPR signal attributes analysis (Böniger & Tronicke, 2010;Forte et al, 2012), techniques to trace reflectors in a semi-automatic or automatic way and obtain three-dimensional horizons, and generation of synthetic radargrams (Carcione et al, 2000;Cassidy, 2007) have made the geometric interpretation of deposits and strata with time line features less dependent on subjective decisions on the part of the data interpreter, based on a mental database of past examples (Chopra & Marfurt, 2005). Additionally, the development of new computational algorithms has enabled the correlation of specific GPR signal characteristics with petrophysical properties of the investigated materials.…”

ABSTRACT. The increased use of Ground-Penetrating Radar (GPR) in several areas of knowledge has introduced an impressive number of new methodological procedures, adapted from other areas, such as seismic reflection, or developed specifically for the GPR. A summary of the advances in acquisition, processing and interpretation of GPR data is presented in this paper. Some of the techniques were applied to a 3D GPR survey in a study area, whose substrate is composed by sedimentary sequences of paleodunes or inactive dunes, located in the outer courtyard of the Department of Geology (DEGEO) of the Universidade Federal do Rio Grande do Norte (UFRN), Brazil. A GPR cube was generated from a regular grid of GPR in-lines and cross-lines, spaced 0.5 m. A filtering routine was applied. For each processing step, the changes in the signal content in the time and frequency domains were analyzed. Common midpoint (CMP) sections and hyperbolas of buried pipes constrained the construction of a subsurface velocity model, allowing the migration and time/depth conversion of the radargrams. Analysis of instantaneous, amplitude, and geometrical attributes and concepts of seismic stratigraphy were applied in the migrated GPR cube to define five stratigraphic sequences and their paleo-reliefs.Based on the radar facies internal geometry, some considerations were established about the depositional environment of the surveyed area.Keywords: GPR, 3D imaging, processing, attribute analysis. RESUMO.A expansão do uso do GPR nas mais diversasáreas do conhecimento tem contribuído para o desenvolvimento de novos procedimentos metodológicos, decorrentes da adaptação de outros métodos geofísicos, principalmente a sísmica de reflexão, ou desenvolvidos especialmente para o GPR. Uma síntese dos avanços nas etapas de aquisição, processamento e interpretaçãoé descrita no presente artigo. Algumas das técnicas analisadas foram aplicadas em dados GPR obtidos em um levantamento realizado segundo uma malha retangular, em umaárea de estudo situada no interior do campus da Universidade Federal do Rio Grande do Norte (UFRN).O substrato imageadoé constituído por camadas de sedimentos arenosos siliciclásticos, de origem eólica costeira, depositados sobre rochas do Grupo Barreiras.Um volume GPR foi gerado a partir de uma malha regular de linhas longitudinais e transversais, espaçadas de 0,5 m. Uma rotina de filtragem dos dados GPRé proposta, sendo as alterações no conteúdo do sinal eletromagnético (EM) analisadas nos domínios do tempo e frequência para cada etapa do processamento. Seções de ponto médio comum (CMP) e hipérboles de tubulações soterradas permitiram a confecção de um modelo de velocidades da subsuperfície e a migração e conversão tempo/profundidade dos radargramas. Análise de atributos instantâneos, de amplitude e geométricos, além de técnicas de interpretação sismoestratigráficas foram aplicadas no volume GPR migrado para definir cinco sequências estratigráficas e seus paleorelevos. Com base nas geometrias internas das radarfácies, foram tecidas algum...
