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

星基辐射计对环境传感，包括气候和天气研究，起着至关重要的作用。然而，这些辐射计在监测大气气体和地面排放方面的作用方式也容易受到人为射频辐射的影响，包括商业宽带系统在24 GHz附近发射的辐射。为了保持辐射计发挥作用的能力，有必要采用新技术来减轻这些辐射的影响。该项目力求利用新模型的开发和通过罗马竞技场测试平台进行的评估，审查减轻干扰影响的技术需求和手段。这项提案描述了审查微波辐射计的最新技术水平的工作以及在不久的将来的运作要求。利用这些信息，提出者将评估在面临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。这将集中在遥感系统和大型卫星星座之间的兼容性。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势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.
