Previous small-scale test pitting suggested that the site might be a locally unique Tang dynasty cemetery, with probable later (Northern Song) activity, but grave definition was problematic and the cemetery's wider extent remained unknown. However, the fine-grained, relatively homogenous background appeared ideal for GPR. A two-stage approach was used: a 400MHz antenna was applied in an initial prospection survey, while both 400MHz and 900MHz were used in a second campaign of higher-resolution intra-site analytical survey. The GPR results identified many `targets' and proved decisive in locating and discriminating both Tang dynasty graves and overlying Northern Song pits. Based on the results of GPR surveys and excavation ground-truthing, it seems the site may in total contain several hundred Tang burials, significant among which were several co-aligned `warrior burials' with iron weapons and tools. Reference to site records of object types (metallic or non-metallic) and sizes shows that the very different slice images by 400MHz and 900MHz GPR are best explained by the radar footprints in First Fresnel zone (FFZ), which is a function of object depth, antenna frequency, GPR wave velocity in soil, and two-way travel time of the objects' reflections. The findings indicate that GPR is in general highly effective on sandy coastal sites, and in particular can provide useful estimates of the size and character of buried archaeological features and artefacts. Based on our findings, more routine application in local archaeology is therefore strongly recommended.","PeriodicalId":187048,"journal":{"name":"2016 16th International Conference on Ground Penetrating Radar (GPR)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115967846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ground-penetrating radar (GPR) surveys were carried out at the rural road network scale using an air-launched pulsed radar system, 1GHz central frequency of investigation, linked to an instrumented van for collecting data at traffic speed. Surveys were performed in two time periods, six months apart from each other. By knowing the geometrical, traffic, climatic and construction information of each surveyed pavement section, and on the basis of comprehensive literature studies dealing with rutting versus time measurements in several flexible pavement sections during their life cycle, it has been possible to determine a reliable domain of existence by means of rutting versus time prediction curves, in which to locate the pavement section-specific prediction curve, case by case. Results have shown reliable relationships, wherein damage prediction is consistent with those suggested by literature.","PeriodicalId":187048,"journal":{"name":"2016 16th International Conference on Ground Penetrating Radar (GPR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131443796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, much can be learned from simple models. For example, a simple Ricker wavelet model can be used to illustrate some fundamental properties of the GPR response from voids, both air- and water-filled. In particular, reflections from the top and the bottom of a void can overlap to a significant extent. Thus, one characteristic of the void response is the occurrence of a “bright spot”, analogous to the “bright spot” observed in seismic exploration for gas. For time delays equal to about half the pulsewidth, the reflected wavelets superimpose to yield maximum reflection amplitudes, significantly greater than individual wavelet amplitudes. The wavelet reflected from the top of a void is not completely separated from the wavelet reflected from the bottom of the void until the time delay due to the void exceeds twice the wavelet pulsewidth. However, the two wavelets can be individually identified at earlier time delays, approximately equal to the wavelet pulsewidth. This is still substantial, and explains why it is difficult to image voids, especially air-filled voids, and to use GPR to infer void thicknesses.","PeriodicalId":187048,"journal":{"name":"2016 16th International Conference on Ground Penetrating Radar (GPR)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131772221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multi-attribute approach is used to characterize the subsurface through different attribute categories, including instantaneous, coherency, and textural attributes applied to quantities related not only to amplitude, phase, and frequency, but also to other parameters calculated from the original data. The different attributes can be integrated into a single view with composite displays (overlays and mixed displays). The proposed procedure is tested in different environments namely: archaeological areas to characterize cultural heritage buried in highly heterogeneous subsurface environments, and glaciers to image their inner structure and to monitor the seasonal changes of firn layers. The results from two case studies demonstrate that the proposed integrated attribute analysis can highlight zones characterized by different electromagnetic parameters, better visualize and quantify GPR features in an automatic and objective manner, and enhance GPR data interpretation in different application fields.","PeriodicalId":187048,"journal":{"name":"2016 16th International Conference on Ground Penetrating Radar (GPR)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116634302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One example is typhoon Durian, a category 3 storm that made landfall on the 30th November 2006, in Bicol province, on the east central Philippine coast. Satellite imagery from May 2007 reveal that Durian caused significant erosion and breached a sandy spit that runs southeast from the mouth of the Quinale River at Bay-Bay village towards Tabaco City. The imagery also showed that, although the breach site showed signs of partial recovery, geomorphological evidence of the inundation event associated with typhoon Durian still remains. In 2012 we mapped the geomorphological features of Durian. In June 2013 we returned to conduct Ground Penetrating Radar (GPR) surveys on the Bay-Bay spit to investigate potential subsurface evidence of previous storm events. The GPR surveys comprised five, 1.5 km, longshore profiles and 12 cross-shore profiles, of 50 m-200 m in length. The GPR system used for this study was a Sensors and Software Noggin with 100 Mhz antennas. Near surface velocities were determined using hyperbolas matching in order to estimate depth. Topographic and positional data were collected using a dGPS system. After minimal processing, depth of penetration during the survey varied from 2-8 m. The cross-shore GPR profiles reveal at least two erosional events prior to 2006 typhoon Durian, with approximately 10 m of recovery and progradation between each erosion surface. Here we show that the GPR profiles captured the erosional features.","PeriodicalId":187048,"journal":{"name":"2016 16th International Conference on Ground Penetrating Radar (GPR)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131975550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
