Collaborative Research: SWIFT: Facilitating Novel Modalities for Spectrum Sharing between Earth-Observing Microwave Radiometers and Commercial Users

基于卫星的辐射计在环境传感，包括气候和天气研究方面发挥着关键作用。然而，这些辐射计的功能手段——感应来自大气气体和地面的辐射——也容易受到人为射频辐射的影响，包括来自商业宽带系统的近24千兆赫的辐射。为了保持辐射计的功能，需要新的技术来减轻这些排放的影响。该项目旨在利用新模型的开发和通过COLOSSEUM测试平台的评估，研究技术需求和减轻干扰影响的方法。本提案描述了研究微波辐射计技术现状的工作，以及在不久的将来运行的要求。利用这些信息，提议者将评估在面对射频干扰时满足这些要求的方法，并对这些方法的可行性进行模拟和测试。这将侧重于遥感系统和大型卫星星座之间的兼容性。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Satellite-based radiometers serve a critical function for environmental sensing, including for climate and weather research. However, the means by which these radiometers function – in sensing emissions from atmospheric gasses and the ground – is also susceptible to human-made radio-frequency emissions, including from commercial broadband systems emitting near 24 GHz. In order to maintain the ability for radiometers to function, new techniques are necessary to mitigate the effects of these emissions. This project seeks to examine both the technical needs and means to mitigate the effects of interference, making use of both the development of new models and evaluation via the COLOSSEUM test platform. This proposal describes work to examine the state of the art in microwave radiometers and requirements for operation into the near future. Using this information, the proposers will evaluate the means to meet these requirements in the face of radio-frequency interference, and both simulate and test these means for viability. This will focus on compatibility between remote sensing systems and large satellite constellations.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
