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.

卫星辐射计在环境传感（包括气候和天气研究）中发挥着关键作用，然而，这些辐射计的工作方式（传感大气气体和地面的排放）也容易受到人为射频辐射的影响。 ，包括来自接近 24 GHz 的商用宽带系统的辐射。为了保持辐射计的工作能力，需要采用新技术来减轻这些辐射的影响。该项目旨在研究减轻这些辐射影响的技术需求和方法。干扰，使使用新模型的开发和通过 COLOSSEUM 测试平台进行评估 该提案描述了检查微波辐射计的最新技术和不久的将来的操作要求的工作，提案者将评估这些方法。面对射频干扰时满足这些要求，并模拟和测试这些手段的可行性。这将重点关注遥感系统和大型卫星星座之间的兼容性。该奖项授予 NSF 的法定任务，并通过评估被认为值得支持。使用基金会的智力价值和更广泛的影响审查标准。
