The 2012 report to the President entitled "Realizing the Full Potential of Government-Held Spectrum to Spur Economic Growth" recommends releasing portions of the large governmental radar bands to be shared with commercial wireless services. This proposal identifies viable sharing mechanisms between radar and communication systems, which traditionally are operated on non-overlapping bands and are engineered to attain very different goals, so that they may co-exist in a way that is minimally harmful, or ideally beneficial, to both. This research first examines the impact unaltered radar and communication systems would have on one another and thereafter proposes a series of solutions for co-existence that range from realistic solutions with respect to legacy systems (where one of the radar or communication systems remains unaltered) to novel transformative joint designs. The availability of proven robust and optimal sharing mechanisms will pave the way to the development of new wireless services while preserving the critical roles radar systems play in the globally networked society.A multidisciplinary team with expertise in radar and statistical signal processing, cognitive radio and spectrum sharing, communication and information theory, and electromagnetics and propagation, has been assembled to address the following thrusts: 1) understand and model the impact of overlapping frequency bands on current, unaltered radar and communication systems; 2) a radar centric approach, where adaptive radar processing is the key to reduce interference from communication systems; 3) a communication network centric approach, where coding is used to improve resilience to radar interference; 4) the joint design of communication and radar systems, where the information-theoretic understanding of the tradeoffs between communication data rates and estimation rates is at the base of this cooperative design; 5) validation of the models and proposed algorithms by using real experimental data. The results of this research will be timely presented at major national and international professional venues; the general public will be reached by means of modern social media, such as videos of undergraduate-run experiments that demonstrate the developed technology and its practical impact. The developed fundamental framework will form a solid foundation for spectrum sharing between radar and communication systems; the developed technology is expected to be of immediate and far-reaching use for both radar and communication private and public sectors alike. Students involved in this research will receive a cutting edge education and training in radar and communication sciences, acquiring fundamental skills to be successful in the current competitive, diverse, and global workforce market.

2012 年向总统提交的题为“充分发挥政府持有频谱以刺激经济增长的潜力”的报告建议释放部分大型政府雷达频段，与商业无线服务共享。该提案确定了雷达和通信系统之间可行的共享机制，这些系统传统上在不重叠的频段上运行，并被设计为实现截然不同的目标，以便它们可以以危害最小或理想地有益的方式共存。两个都。这项研究首先检查了未改变的雷达和通信系统对彼此的影响，然后提出了一系列共存解决方案，范围从针对遗留系统（其中一个雷达或通信系统保持不变）的现实解决方案到新颖的变革性关节设计。经过验证的稳健和最佳共享机制的可用性将为新无线服务的开发铺平道路，同时保留雷达系统在全球网络社会中发挥的关键作用。一支在雷达和统计信号处理、认知无线电和频谱方面拥有专业知识的多学科团队共享、通信和信息理论以及电磁学和传播，旨在解决以下问题：1）了解重叠频段对当前未改变的雷达和通信系统的影响并对其进行建模； 2）以雷达为中心的方法，其中自适应雷达处理是减少通信系统干扰的关键； 3）以通信网络为中心的方法，其中编码用于提高雷达干扰的恢复能力； 4）通信和雷达系统的联合设计，其中对通信数据速率和估计速率之间权衡的信息论理解是该合作设计的基础； 5）使用真实的实验数据验证模型和提出的算法。本研究成果将及时在国内外主要专业场所展示；将通过现代社交媒体接触公众，例如展示所开发技术及其实际影响的本科生实验视频。所开发的基本框架将为雷达和通信系统之间的频谱共享奠定坚实的基础；所开发的技术预计将对雷达和通信私营和公共部门产生直接和深远的影响。参与这项研究的学生将接受雷达和通信科学方面的前沿教育和培训，获得在当前竞争激烈、多元化的全球劳动力市场中取得成功的基本技能。
