A bulk good made of chunks of sand-lime brick is non-destructively inspected with the objective to survey the interior and to robustly detect discontinuities in the permittivity which might indicate a buried target. The method employs the theory of Pauli scattering matrix decomposition onto the quad-polarized Radar data to improve the detection decision. The investigations are applied to three scenarios, i.e. a model of an assault rifle, the same rifle completely buried under chunks of sand-lime brick and just a bulk good made of the same chunks. Within these investigations a novel broadband dual-polarized antenna which operates between 0.8 to 8 GHz was developed. The main features of the tapered slot lines Vivaldi antennas are a high polarization purity and a symmetric layout resulting in equal phase centres for both polarizations. The experimental validation promises for improved detection capability of buried targets by simultaneously providing high range resolution.","PeriodicalId":159159,"journal":{"name":"2013 IEEE International Conference on Ultra-Wideband (ICUWB)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124793877","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 electronic device helps to examine hard-to-reach parts of the gastrointestinal (GI) tract with significantly less discomfort for the patient than traditional endoscopic methods based on the insertion of flexible tubes. A CE has the size and shape of a pill, and after being swallowed it transmits wirelessly images of the GI tract to an external receiver worn by the patient. The images are captured with the aid of an integrated tiny camera and a light source. Through the use of sophisticated software, a video is created offline with the received images for analysis and inspection by the medical staff. In most cases, real-time video transmission is not possible. A number of commercial CE systems operating with narrowband radio interfaces are already available. Nevertheless, the quality of the CE video is generally poorer than conventional endoscopy's. The use of an ultra wideband (UWB) radio interface, which can enable high data rate transmission, would significantly enhance the video quality and reduce power consumption. The low power consumption feature could be exploited to add functional tools for purposes like biopsy or targeted drug delivery to current CE systems. Nevertheless, the high attenuation of radio signals propagating through living tissues in frequencies above 1 GHz make the use of UWB radio links for this application a major challenge. In addition, the design of an appropriate high data rate transmitter and a tiny antenna for efficient transmission over a large bandwidth are complicate tasks that require an accurate characterization of the channel. This paper presents the most important research results that we have obtained towards the implementation of a UWB-CE. Challenges and research problems in this area are outlined.","PeriodicalId":159159,"journal":{"name":"2013 IEEE International Conference on Ultra-Wideband (ICUWB)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126473620","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 aim of this study was to design such an antenna that achieves the maximum antenna gain over a bandwidth between 1 GHz to 10 GHz while minimizing the size of the antenna. The idea was to make use of combined respective advantages of Vivaldi antennas and TEM Horn antennas to achieve the desired goals by shaping the TEM Horn antenna to look like a Vivaldi antenna. The antenna structure was modified by partially dielectric loading it in the center to increase the gain and bandwidth. It was placed in a surrounding box made of PEC material to reduce the undesired side lobes to obtain a more directive radiation pattern. The simulations were performed by using the CST STUDIO SUITE Electromagnetic (EM) Simulation software. The results showed that the Vivaldi Shaped Partially Dielectric Loaded (VS-PDL) TEM horn antenna with 5 cm aperture depth had the best gain values over the desired bandwidth. This antenna is considered as compact enough for applications like hand-held impulsive Ground Penetrating Radar (GPR) and Electromagnetic Compatibility (EMC) measurement systems due to its reduced size and shielded metallic box structure.","PeriodicalId":159159,"journal":{"name":"2013 IEEE International Conference on Ultra-Wideband (ICUWB)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131223453","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 baseband can support various data rates such as 850 Kb/s, 6.81 Mb/s and 27.24 Mb/s. The design and parameter selection were considered carefully taking into account all possible imperfections that IR-UWB high frequency signal can experience. Energy detection receiver employing a comparator clocked at 499.2 MHz was adopted for the digitisation. Using I and Q path both positive and negative pulses were detected with a high reliability leading to a very good synchronisation performance. Simulation results confirm that the synchronisation is very robust being always correct for office NLOS environment and a large clock deviation between transmitter and receiver. The algorithm presented in this paper was implemented with discrete components, FPGA and signal generators. Experimental results show a good agreement with the simulation for all the data rates and the implemented baseband offers around six meter communication range tested along with a high frequency frontend from discrete components.","PeriodicalId":159159,"journal":{"name":"2013 IEEE International Conference on Ultra-Wideband (ICUWB)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131614150","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}

By simply correlating the outputs of energy integrators with decoding codes, the GCM receiver detects information symbols without the need of delay components for transmitted reference or analog carriers for frequency-shifted reference. In addition, the GCM systems subsume existing code-multiplexing designs such as code-multiplexed transmitted reference (CM-TR) and code-shifted reference (CSR) and could even provide better error performance and/or higher data rate. However, the existing GCM receiver is generally not a maximum likelihood detector (MLD). In this paper, we propose MLDs for GCM systems based on the statistics of the signals of GCM receivers. With the aid of the statistics, the MLDs for GCM systems inherit the simple non-coherent structure of GCM receivers and further improve the error performance. Extensive simulations are conducted to show the considerable performance gain of the proposed MLDs compared to the GCM receivers for both CSR codes and optimal GCM codes.","PeriodicalId":159159,"journal":{"name":"2013 IEEE International Conference on Ultra-Wideband (ICUWB)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124995700","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}
