EXP-SA: Enhanced Quadrupole Resonance Technology for Explosive Detection

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，如氮同位素14N，普遍存在于许多形式的烈性炸药中，如TNT和RDX。QR类似于医学上使用的磁共振成像技术，提供了一种高度具体的探测和识别爆炸物的方法。由于QR不使用电离辐射或强磁场，因此使用和运输安全可靠。然而，对于非屏蔽QR系统，射频干扰（RFI）抑制和系统灵敏度的提高是至关重要的。非屏蔽QR系统仍然不成熟，需要进一步发展才能真正成为实用可靠的爆炸物检测系统。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，旨在解决与当前无屏蔽QR系统局限性相关的潜在传感器系统技术问题。智力优势：拟议的研究旨在推进传感器和传感器网络新技术的基础知识，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，同时推进多个领域的工程知识。我们充分预期，该项目的成功实施将大大提高用于爆炸物探测的无屏蔽QR系统的能力。这项研究的结果将为广泛的多学科研究提供新的机会，从QR传感器到鲁棒自适应阵列处理技术。更广泛的影响：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和研究生课程，为21世纪的工程学生做好准备。工业合作将促进技术从学术界向工业界的转移。我们的研究生和本科生教育活动的核心是招募和指导女学生和传统上代表性不足的群体的学生作为研究助理。通过佛罗里达大学研究生工程电子交付（EDGE）在全州范围内提供相关的信号处理课程，向佛罗里达州的非传统和贫困的非佛罗里达大学学生提供教育服务。

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).
