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).

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14 N，在许多形式的烈性炸药中普遍存在，如TNT和RDX。QR类似于医学中使用的磁共振成像技术，并提供了一种高度特异性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，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。无屏蔽QR系统仍不成熟，需要进一步开发，才能成为真正实用和可靠的爆炸物探测系统。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，旨在解决与非屏蔽QR系统当前限制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，特别是在预测和检测爆炸物和相关威胁方面，同时推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显着提高非屏蔽QR系统的爆炸物检测能力。这项研究的结果将提供新的机会，在广泛的多学科研究，从QR传感器到强大的自适应阵列处理technology.Broader影响：教育计划的重点是准备学生在21世纪的工程，通过纳入跨学科的设计和解决问题的技术到本科和研究生课程。工业合作将促进从学术界到工业界的技术转移。我们的研究生和本科生教育活动的核心是招聘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。教育推广到整个佛罗里达州的非传统和贫困的非UF学生将通过提供相关的信号处理课程全州通过研究生工程（EDGE）的UF电子交付实现。
