The high timing stability of the recorded signal needed for phase analysis is met by clocking all circuits, including the stroboscopic timer, with a quartz disciplined reference signal. We demonstrate 21 ps timing stability when measuring the long term evolution of two echoes separated by 300 ns, consistent with the ability to measure with 1 K resolution surface acoustic wave transducers designed as GPR cooperative sensors, dedicated to temperature sensing in the current demonstration. The solution takes advantage of some of the latest microcontroller peripherals including a timer with 217 ps resolution, for an equivalent time sampling up to 4.6 GS/s. Wireless measurement at a range of 70 cm is demonstrated through air, with a signal to noise ratio allowing for far range measurement in dielectric sub-surface media.","PeriodicalId":269482,"journal":{"name":"2018 17th International Conference on Ground Penetrating Radar (GPR)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128315609","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}

And the analysis and noise suppression of GPR data have always been the research focus. In this study, a new self-adaptive time-frequency decomposition tool called the variational mode decomposition (VMD) is introduced. We use the VMD method to derive a set of stationary sub-components, and based on the decomposition, we separate the valid signals and the components which are corresponded to the noise. One trace of GPR data are given to test the effect of the VMD decomposition, and the empirical mode decomposition (EMD) is also employed as a comparison. And a primary noise-suppression method based on the VMD scheme is also proposed. The application of the field GPR data further demonstrates the better performance of the proposed method in both noise suppression and the retention of geophysical events.","PeriodicalId":269482,"journal":{"name":"2018 17th International Conference on Ground Penetrating Radar (GPR)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116084424","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}

This method evaluates the lateral wave amplitude of CMP gathers by a multiple-input and multiple-output (MIMO) GPR system YAKUMO. The system operates in the frequency range from 50 MHz to 1.5 GHz. It consists of 8 transmitting antenna array and 8 receiving antenna array. Each antenna has 24 cm separation spacing, both transmitting and receiving antenna array. Considering the antenna configuration and designing survey lines spacing, amount of CMP gathers could extract out in a large survey area. After the amplitude correction, the lateral wave amplitude of each CMP gather was analyzed. In particular, this method allows us to distinguish the multiple echoes contribution which was generated by the stripping phenomenon occurred between asphalt layers. The real application demonstrated this method at Tokyo International airport taxiway. The method shows a high consistency of the traditional sounding method. It provides an innovative way for the stripping detection of the partially damaged pavement while were hard to be observed by the reflected signals.","PeriodicalId":269482,"journal":{"name":"2018 17th International Conference on Ground Penetrating Radar (GPR)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114185869","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}

The ALIS system is compact and light weight which is less than 3.1kg, and can be used for more than 6 hours. ALIS is a dual sensor, which combines EMI (Electromagnetic Induction) sensor and GPR (Ground Penetrating Radar). This is a hand held sensor, equipped with position tracking system, therefore ALIS can acquire the EMI and GPR signal together with its position information, while it is scanned on the ground surface by an operator by hand manually. Then, the data can be processed using Synthetic Aperture Radar (SAR) processing (migration) and can reconstruct 3-D subsurface image. GPR of ALIS operates at 1-3GHz, and the penetration depth of the GPR is 20-50cm. The development of ALIS started in 2002, and after evaluation test in some mine affected countries including Afghanistan, a long-term evaluation test has been conducted in Cambodia since 2009. We found that the prototype of ALIS is capable for imaging buried mines, and can reduce the false alarm ratio drastically. We have detected more than 80 buried land mines in Cambodia mine fields. The ALIS is based on these practical evaluation conducted together with CMAC (Cambodian Mine Action Center).","PeriodicalId":269482,"journal":{"name":"2018 17th International Conference on Ground Penetrating Radar (GPR)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117009199","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}

In prior seasons, magnetic gradiometry survey revealed much of the form and fabric of the city, and this season we decided to complement these results with GPR investigations in the hope of obtaining more detailed 3-dimensional results in targeted areas of the site. The survey was undertaken with 200 and 400 MHz shielded antennae with a focus on mapping the bedrock profile as well as features within 2.5m of the ground surface. The survey areas across the site targeted places where the results could best help answer the research questions of the project and include a terrace near the city wall overlooking the valley to the north with two visible threshold blocks and two terraces to the east side of the site which prior survey has shown were likely domestic spaces. The purpose of surveying these areas was to explore the possible buried roads and houses, more precisely mapping them and identifying their depth. The collected data have been combined to produce a 3-D cube representing the features laying beneath the subsurface. From these 3-D cubes, it is possible to produce amplitude time-slices at various depths below the surface, which show the anomalies detected during the survey. The initial results of the GPR survey have been inspiring and will contribute greatly to our understanding of the site, while also forming the basis for future investigations through further survey or excavation.","PeriodicalId":269482,"journal":{"name":"2018 17th International Conference on Ground Penetrating Radar (GPR)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128243281","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}
