Collaborative Research: Investigation of Spectrum Sharing Between Radar and Wireless Communications Systems

该项目将使无线电频谱这一稀缺资源得到更有效的利用。该项目将通过提高公民之间的通信效率，同时共享雷达应用的相同频率范围，对公众产生广泛的影响。所开发的技术将潜在地减少意外和故意（干扰）干扰的影响。学生们将进行部分研究，他们将得到更好的培训，以加入美国的劳动力大军。此外，他们在课堂演讲中使用的研究将使他们更敏锐地认识到允许广泛使用认知无线电设备所面临的使用和问题，这些设备可以随意改变其无线频道。该提案探索了合成孔径雷达与频谱的其他用户一起工作的潜力。特别是，它旨在探索雷达系统通过识别和丢弃假阳性信号来有效运行的能力；实际上是通过使用多种方案来识别和忽略干扰。他们的方法是独特的，因为它试图将频谱共享整合到雷达的基本操作中。

This project will enable more efficient use of a scarce resource, the radio spectrum. This project will have broad impact on the public by enabling increased efficiency in communications between citizens, while simultaneously shared use of the same frequency range for radar applications. The techniques developed will potentially reduce the impact by both accidental and intentional (jamming) interference. Students, who will carry out part of the research, will be better trained to join the US work force. Furthermore, their use of the research in the classroom presentations will lead to a keener appreciation of the use and issues faced by permitting widespread use of cognitive radio devices, devices that can change its wireless channel at will.This proposal explores the potential for Synthetic Aperture Radars to operate with other users of the spectrum. In particular it aims to explore the capacity for a Radar system to operate efficiently by recognizing and discarding false positive signals; in effect by using a variety schemes to identify and ignore interference. Their approach is unique in that it attempts to integrate the spectrum sharing into the fundamental operation of the radar.
