EXP-SA: Enhanced Quadrupole Resonance Technology for Explosive Detection

0729727Li四极共振(QR)是一种射频(RF)技术，提供了一种明确的方法来检测四极核的存在，例如氮同位素14N，在TNT和RDX等许多形式的烈性炸药中普遍存在。QR类似于医学上使用的磁共振成像技术，提供了一种高度特异的检测和识别爆炸物的方法。由于QR不使用电离辐射或强磁场，使用和运输安全可靠。然而，对于非屏蔽QR系统，抑制射频干扰(RFI)和提高系统灵敏度是至关重要的。非屏蔽QR系统仍然不成熟，需要进一步开发才能真正实用和可靠地用于爆炸物检测。佛罗里达大学(UF)与瑞典卡尔斯塔德大学、英国伦敦国王学院和通用电气安全公司合作，提出了一项为期3年的跨学科研究计划，旨在解决与当前非屏蔽QR系统的局限性相关的潜在传感器系统技术问题。智力价值：拟议的研究力求增进传感器和传感器网络新技术的基本知识，以及在控制和决策中使用传感器数据，特别是与爆炸物和相关威胁的预测和探测有关的基础知识，同时促进多个领域的工程知识。我们完全预计，该项目的成功实施将大大提高非屏蔽QR系统用于爆炸物探测的能力。这项研究的结果将在从QR传感器到稳健的自适应阵列处理技术的广泛的多学科研究中提供新的机会。广泛的影响：教育计划的重点是通过将跨学科设计和解决问题的技术纳入本科生和研究生课程，为21世纪的工程做好准备。产业界的合作将促进技术从学术界向产业的转移。我们研究生和本科生教育活动的核心是招募和指导女学生和来自传统上代表人数较少的群体的学生作为研究助理。通过在全州范围内通过UF工程研究生电子教学(EDGE)提供相关的信号处理课程，将实现对佛罗里达州非传统和贫困非UF学生的教育推广。

0729727Li Quadrupole Resonance (QR) is a radio frequency (RF) technique offering an unequivocal way of detecting the presence of quadrupolar nuclei, such as the nitrogen isotope 14N, prevalent in many forms of high explosives such as TNT and RDX. QR is similar to magnetic resonance imaging techniques used in medicine and offers a highly specific method of detecting and identifying explosives. Because QR does not use ionizing radiation or strong magnetic fields, it is safe and reliable to use and transport. For unshielded QR systems, however, radio frequency interference(RFI) suppression and system sensitivity improvement are critical. Unshielded QR systems are still immature and require further development to become truly practical and reliable for explosive detection. The University of Florida (UF), in collaboration with Karlstad University of Sweden, King's College London of UK, and GE Security, proposes a 3-year interdisciplinary research plan aimed at addressing the underlying sensor system technical issues associated with current limitations of unshielded QR systems. Intellectual Merit: The proposed research seeks to advance fundamental knowledge in new technologies for sensors and sensor networks, and in the use of sensor data in control and decision making, particularly in relation to the prediction and detection of explosives and related threats", while advancing engineering knowledge in multiple fields. We fully anticipate that the successful implementation of this project will significantly advance the capability of unshielded QR systems for explosive detection. The results of this study will provide new opportunities in a wide range of multidisciplinary studies ranging from QR sensors to robust adaptive array processing techniques.Broader Impacts:The focus of education plan is to prepare students for engineering in the 21st century through the incorporation of interdisciplinary design and problem-solving techniques into both the undergraduate and graduate curriculum. The industrial collaborations will facilitate the technology transfer from academia to industry. Central to both our graduate and undergraduate educational activities is recruitment and mentoring of female students and students from traditionally underrepresented groups as research assistants. Educational outreach to non-traditional and underprivileged non-UF students across the state of Florida will be achieved by offering the related signal processing courses state-wide via the UF Electronic Delivery of Graduate Engineering (EDGE).
