Opis:
The Ground Penetrating Radar (GPR) technique finds immense applications in civil engineering today, as the most suitable approach for non-destructive testing of pavements, highways, concrete structures, and more. The major challenge in carrying out a GPR evaluation is that the properties of the probed medium are usually unknown. The permittivity and conductivity of the medium may vary from those of air to water. The electromagnetic waves also have a frequency dependent attenuation. The ability of GPR to detect signals reflected and scattered by the targets largely depends upon the antenna performance. This paper studies a novel 11:1 wideband loop bowtie antenna with very good radiation properties in the entire operating bandwidth. Synthetic and experimental results are presented for the return loss and gain of the antenna. Furthermore, experimental results are presented for the radiation patterns in the E- and H-plane. We also used the antenna to measure B-scans over two different pipes, a bamboo, and a reinforced concrete structure. All results obtained with the proposed antenna have been compared with results obtained by using a RC loaded antenna. It has been found that the loop bowtie antenna has excellent detection capability and produces less clutter. The loop loading technique can be applied to existing antennas for improved GPR imaging. This will improve the detectability of GPR by improving the target return signal.

Opis:
In this paper, complex signal analyses of ground penetrating radar (GPR) field data over an area of farmland in Krakow were interpreted alongside the basic filtered field data. The farmland was simulated with varying degrees of soil compaction induced by tractor movement. The focus of the study was the delineation of inherent characteristics of media through which the electromagnetic energy travelled. Fourteen GPR profiles were acquired from the area. The field data were subjected to pre- and post-processing prior to its the presentation and interpretation. Advance analysis operations on the field data which resorted in different attributes reveal more about the effects of the compaction on the soil than indicated by the basic filtered field data. Better resolution of subsurface layers boundary and lateral variation in the physical properties of the traversing media were well elucidated. The results have demonstrated that an advanced signal processing such as used in the study has ability to depict subtle characteristics of the propagating media.

Opis:
Geophysical prospection and small-scale archaeological excavation were undertaken on the site of Kaštelina, a Late Iron Age hillfort settlement located on the Stolac promontory in the eastern part of Rab island (Kvarner Gulf, Croatia). Within the frame of the “Archaeological topography of the island of Rab” program, a Polish–Croatian team applied a series of multidisciplinary methods to study the occupational history of the site, its preservation, the nature of selected site features and future research potential. Ground-penetrating radar and magnetometer surveys, combined with the implementation of the Amplitude Data Comparison (ADC) method, led to the detection of remains of Late Iron Age building structures distributed over the northwestern side of the Stolac promontory. Archaeological excavations verifying the findings of the geophysical survey resulted in the discovery of a dwelling with associated outdoor features. A preliminary assessment of the outcome of a multidisciplinary approach to the study of the site of Kaštelina emphasizes the importance of the collected data for a general understanding of Late Iron Age settlements and their internal organisation in a wider context.

Opis:
A method of processing GPR signals based on previously developed algorithms is proposed. The purpose of the study is to increase the accuracy of thickness measurements of near-surface thin layers of multilayer structures. The main idea of the method is to layer-by-layer restoration of physical and geometric characteristics of plane-layered media, for example, car coverings. As a result, with the help of numerical modelling, the operability and practical effectiveness of the proposed method was established. In addition, schemes for the practical implementation of this approach have been proposed for the processing of sounding data of pavement structures using a pulsed ground-penetrating radar "TRF-1". The use of additional procedures, for example, GPR calibration based on data obtained by core sampling, also improves the reliability and accuracy of assessing the current state of road pavements.

Opis:
Sand dunes are the most prominent subjects of geological and geomorphological interest along the Curonian Spit - a mega-barrier that separates the Curonian Lagoon from the Baltic Sea. To date, an assessment of various parameters of migrating dunes along the spit has been based on comparative analysis of old maps or aerial and satellite images, as well as geodetic measurements. These investigations have allowed assessment of dune dynamics over a relatively short historical period (~1700s to present). The most recent detailed investigations of the Dead (Grey) Dunes along the Lithuanian part of the spit using ground-penetrating radar (GPR) and magnetic susceptibility (MS) surveys, supported by a radiocarbon (14C) chronological framework of palaeosols and infrared optically stimulated luminescence (IR-OSL) ages of sand horizons, have advanced our understanding of aeolian landscape evolution. The interpretation of dune activity and stability phases has been generally based on IR-OSL dating results of the sand layers located between radiocarbon-dated palaeosols. However, the influence of soil-forming processes on the IR-OSL dating results related to possible migration of natural radioactive isotopes via aeolian sand layers has not been previously considered. Hypotheses of dune reactivation and migration caused by abrupt regional climate shifts, catastrophic forest fires, anthropogenic influence, and more local forcings have been tested. An integrated approach to dune investigations has offered an estimate of the rates of sand accumulation and key phases of aeolian dynamics during both stormy and calm periods, as well as helped to extend the record of dune evolution to the mid-Holocene. The palaeoenvironmental and palaeodynamic reconstructions of the Dead Dunes suggest that this mid-Holocene phase of dune activity was of a local character and likely did not exceed several centuries.

Opis:
The article considers the issues of applying ground penetrating radar (GPR) technologies for engineering purposes concerning subsurface research. It describes the field of application of GPR research during road construction and operation and the advantages and disadvantages of this type of engineering survey. It presents comparative data on the accuracy (inaccuracy) of existing GPR control methods applied to determine the thickness of the monolithic pavement layers in Europe, CIS, and the USA. The main provisions of the GPR survey procedure are described, including four main stages: the analysis of initial materials of surveyed section and equipment preparation; GPR survey; geological verification; processing and interpreting of radargrams; and the preparation of a report. Geophysical works were performed using the geo-radar of the OKO series as part of the road measuring complex DVK-05 on the section of the Astana-Petropavlovsk A-1 highway with cement concrete pavement and on the section of the R-12 "Kokshetau - Atbasar" with asphalt pavement. The example of a radargram and the core sample of a cement concrete pavement taken during geological verification of the thickness of a monolithic layer is presented. Graphs of variation in the thickness of pavement layers by radargrams of longitudinal passages in the indicated road sections with the assumptions about the nature of the heterogeneity of the obtained values are given. The obtained results on the thickness of monolithic layers (cement concrete and asphalt concrete) were assessed on the criteria of quantitative deviation from the required standard value. Recommendations were provided to address positive deviations in the thickness of monolithic pavement layers at various stages of the road survey.

Artykuł przedstawia zarys problematyki procesu identyfikacji skazanych na karę śmierci i rozstrzelanych w Polsce w latach 1944–1956. Opisuje zastosowane metody badawcze: analizę materiałów źródłowych, badanie georadarowe oraz badania porównawcze materiału DNA na przykładzie największych prac w Polsce, m.in. kwatery „Ł” Cmentarza Wojskowego przy ul. Powązkowskiej w Warszawie i Aresztu Śledczego w Białymstoku. Aerial photographs and DNA material in the process of identifying sentenced to death and shot in Poland in 1944–1956 – An outline of the issue An individual approach to the process of identifying fallen victims of armed conflicts in the 20th century enjoys widespread popularity in Western Europe (Germany, Holland), Central and Eastern Europe (Croatia, Bosnia and Herzegovina), Anglo-Saxon countries (especially USA) and Russia. Each of them is characterized by different identity determination resulting from the circumstances surrounding the death of a murdered person. The development of technology makes it possible for us to use methods that were inaccessible ten years ago: DNA comparative studies that ultimately verify the identity of a victim. The studies have been used for over twenty years to restore the identity people who were murdered and lost in the aftermath of the armed conflict in former Yugoslavia, especially Slovenia, Croatia, Bosnia and Herzegovina. In Poland, the identification of bone remains was carried out in certain individual cases, such as the skull of Ludwik Szymański, a Polish officer murdered in Katyn. Mass comparative studies of the DNA of the wanted people and their families were first used in Poland against anti-communist soldiers of the independence underground, who were sentenced to death in 1944–1956 by military district courts and shot in the prison in Rakowiecka Street in Warsaw.The article presents the research methods used in Poland, such as the analysis of source materials, geo-radar survey and comparative research of DNA material on the example of the largest works. The aim of the paper is to present sources materials that have contributed to locating and then estimating the size of burial fields. The author also describes other methods of identifying victims, critically presenting each of them.

Opis:
This paper presents a suggested approach for forensic investigation of bridge decks in which Ground penetrating radar (GPR) consisting of two antennas is used to assess the current conditions. The methodology was tested on a bridge deck in central Sicily. The acquired data were analyzed for identifying the asphalt overlay thickness, concrete cover depth and deck thickness and location of the rebar reinforcement. In the proposed approach for assessing bridge deck conditions the GPR survey was complemented with (i) a site investigation on layer thicknesses for calibration/verification purposes of the GPR response and (ii) a Terrestrial Laser Scanning system (TLS) to verify the bridge design slab curvature. The study shows that this methodology has significant merits on accurately assessing such bridge deck components when bridge design records are non-existing, and by using non-invasive methods such as laser scanning and GPR. The great advantage provided by the TLS technique is the possibility to obtain a 3D output model of the scanned element with the accuracy of the best topographic instruments in order to complement GPR data surveys for bridge inspection.

Opis:
The study uses quantitative methods to analyse the latest Bartonian to Early Rupelian sedimentary succession at the SE outskirts of the Polish Lowland Paleogene Basin, in the back-bulge zone of the Carpathian orogenorebulge. The vertical lithotype proportion diagrams from a large number of well logs are compiled to reveal the area’s sequence stratigraphy. Six sequences are recognized and correlated with 3rd-order eustatic sea level cycles. The basal sequence of type 1 is overlain by three sequences of type 2 and followed by a fifth sequence of type 1, whose depositional forced-regressive and lowstand systems tracts brought the main volume of quartz-glauconite sand to the study area. The study focuses further on the deposits of this fifth sequence, exposed and surveyed with GPR in the Nowodwór-Piaski sand pit. Their sedimentary facies analysis reveals the local spatial pattern of a wave-dominated and tidally-influenced sedimentation, supporting the earlier notions of a southern palaeoshoreline and a tectonically-controlled sedimentation.The analysis, aided by multidimensional GPR survey, indicates syndepositional development of a tectonic graben filled laterally by fault scarp-attached large sand bars and an axial action of tidal ebb currents. The bars were formed of shore-derived sand swept by littoral waves from the graben footwall areas. As the graben’s tectonic activity ceased, it became buried by the lowstand regressive sands overlain by gravelly foreshore deposits, most of which were later removed by the Pleistocene glacial erosion. A 3D model of the deposits in the Nowodwór-Piaski area is constructed on the basis of outcrop and GPR data with the use of multiple-point statistical methodology to depict the internal architecture, heterogeneity and spatial relationships of main sedimentary facies. The model can serve as a guide for the future exploration and exploitation of the quartz-glauconite sands in the area and as instructive example of how a petroleum reservoir model of a complex sedimentary succession can be constructed with the use of modern statistical methods.

Opis:
Ground Penetrating Radar is commonly used in civil engineering sectors. Underground anomalies (i.e., electric wires, water pipes or sinkholes) can be detected through representations of hyperbolae in the measured processed GPR image. Our work focuses on detecting the underground objects and understanding their metallic or nonmetallic characteristics. The max energy difference attribute is applied to illuminate their positions while phase analysis process can determine change of phase spectrum in the diffracted signals. For improving phase analysis, we applied a novel workflow combining conventional processed steps and a zooming step for preserving phase originality without disturbed by any unnecessary filters. We applied the workflow in model and real data for proving its effectiveness. Interpretation of two real datasets in Vietnam by our workflow can express existences of the artificial underground anomalies as well as their matter characteristics comparing to their surrounding environments.
Ground Penetrating Radar jest powszechnie stosowany w inżynierii lądowej i wodnej. Podziemne anomalie (np. przewody elektryczne, rury wodociągowe lub zapadliska) można wykryć za pomocą reprezentacji hiperbol w zmierzonym przetworzonym obrazie GPR. Nasza praca koncentruje się na wykrywaniu podziemnych obiektów i zrozumieniu ich metalicznych lub niemetalicznych wła-ściwości. Atrybut maksymalnej różnicy energii jest stosowany do oświetlania ich pozycji, podczas gdy proces analizy fazowej może określić zmianę widma fazowego w dyfrakcyjnych sygnałach. Aby usprawnić analizę fazową, zastosowaliśmy nowatorski przepływ pracy łączący konwencjonalne kroki przetwarzania i krok powiększania w celu zachowania oryginalności fazy bez zakłócania przez niepotrzebne filtry. Zastosowaliśmy przepływ pracy w modelu i rzeczywistych danych, aby udowodnić jego skuteczność. Interpretacja dwóch rzeczywistych zbiorów danych w Wietnamie za pomocą naszego przepływu pracy może wyrazić istnienie sztucznych anomalii podziemnych, a także ich charakterystykę materii w porównaniu z otaczającym je środowiskiem.

Opis:
Ground Penetrating Radar (GPR) systems arenowadays standard inspection tools in several application areas, such as subsurface prospecting, civil engineering and cultural heritage monitoring. Usually, the raw output of GPR isprovided as a B-scan, which has to be further processed inorder to extract the needed information about the inspectedscene. In this framework, inversescattering-based approachesare gaining an ever-increasing interest, thanks to their capabilities of directly providing images of the physical and dielectricproperties of the investigated areas. In this paper, some advances in the development of such inversion techniques in theGPR field are revised and discussed.
