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，它具有一种明确的方式，可以检测到存在四极核的存在，例如氮同位素14N，在许多形式的高爆炸物（例如TNT和RDX）中流行。 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定的检测和识别炸药的方法。由于QR不使用电离辐射或强磁场，因此使用和运输是安全且可靠的。但是，对于未屏蔽的QR系统，射频干扰（RFI）抑制和系统敏感性提高至关重要。未屏蔽的QR系统仍然不成熟，需要进一步的开发才能真正实用和可靠地进行爆炸性检测。佛罗里达大学（UF）与瑞典的卡尔斯塔德大学，英国伦敦国王学院和GE Security合作，提出了一项为期3年的跨学科研究计划，旨在解决与当前未持续QR系统限制相关的潜在传感器系统技术问题。智力优点：拟议的研究旨在提高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时，尤其是与预测和发现爆炸物和相关威胁有关的方面”，同时促进了多个领域的工程知识。我们完全预测了该项目的成功实施了该项目的实施，该项目的实施能力是QR的QR QR QR QR的实施。从QR传感器到强大的自适应阵列处理技术的各种多学科研究的新机会。BROADER的影响：教育计划的重点是在21世纪通过跨学科设计和解决问题的技术融入到跨学科和培养工业的过程中。我们的研究生和本科教育活动的核心是招募和指导传统代表性群体的女学生和学生作为研究助理的学生。佛罗里达州非传统和贫困的非UF学生的教育宣传将通过通过UF电子工程（EDGE）提供全州范围内的相关信号处理课程来实现。
