Objective:The objective of the proposed project is to explore the problem of scanning large amounts of spectrum in order to detect anomalous usage of that spectrum. The project will examine spectrum scanning using a single spectrum sensor and using multiple spectrum sensors. The approach will involve using game theoretic formulations that allow for the determination of scanning strategies that give an optimal likelihood of detecting an adversarial or accidental misuse of spectrum in terms of the bandwidth that can be scanned in a single scan and the bandwidth that an anomalous activity might involve. The optimization of strategies are complemented by techniques that increase the amount of spectrum that can be scanned in a single scan, and spectrum mapping algorithms that estimate the received power levels at arbitrary spatial locations.Intellectual merit:The intellectual merit of the proposed effort stems from the pulling together of a mixture of technologies from different fields, including game theory, signal processing, security, wireless communications, and RF photonics to address the challenging problem of detecting and preventing anomalous spectrum activity across a wide swath of bandwidth. Broader impacts:The broader impacts of the proposed effort will include the cross-pollination between different disciplines, such as game theory, security, photonics and signal processing. Additionally, the project will guide the development of graduate and undergraduate students at both participating institutions, giving the students new tools with which to contribute to wireless and optical communications. Finally, new interdisciplinary curricula will be developed as part of the effort.

目的：拟议项目的目的是探讨扫描大量频谱的问题，以便检测该频谱的异常使用。该项目将使用单个频谱传感器和多个频谱传感器检查频谱扫描。该方法将涉及使用博弈论公式，允许确定扫描策略，根据单次扫描可扫描的带宽和异常活动可能涉及的带宽，提供检测对抗性或意外滥用频谱的最佳可能性。通过增加单次扫描可扫描的频谱量的技术以及估计任意空间位置接收功率电平的频谱映射算法，可以补充优化策略。知识价值：该计划的知识价值源于将不同领域的技术结合在一起，包括博弈论、信号处理、安全、无线通信和射频光子学，以解决在宽带宽范围内检测和防止异常频谱活动的挑战性问题。更广泛的影响：提议的努力的更广泛的影响将包括不同学科之间的交叉授粉，如博弈论，安全，光子学和信号处理。此外，该项目将指导参与院校的研究生和本科生的发展，为学生提供新的工具，为无线和光通信做出贡献。最后，将开发新的跨学科课程，作为这项工作的一部分。
