SBIR Phase I: Development of a radiometric receiver for 183 GHz.

该项目的更广泛影响/商业潜力在于改进和简化各种平台的天气观测，如无人驾驶飞机、轨道上的小型卫星、海洋中央的浮标或从地面，甚至在偏远地区的浮标。辐射计接收机的目标客户是任何希望获得更详细、本地化、短期预报的人。这些客户包括私营和政府的气象组织、可再生能源工厂的运营商。陆上和海上风力发电场或太阳能发电厂，未来用于观测大气、军事和其他领域的无人驾驶或机器人飞机。装有这些接收器的传感器还有助于远程探测通用航空中的飞行结冰危险。我们的传感器将简化小型飞机（有人驾驶或无人驾驶）的观测，从而允许对云、其水或冰含量以及大气的局部热力学状态进行新的观测。这样的观测将提高对云及其在气候和地球系统模式中的表现的科学认识。更广泛地说，该项目代表了亚太赫兹接收机设计和组装的新技术概念。亚太赫兹接收器的用户包括机场安检（人体扫描仪）、短距离高比特率通信、纸张、聚合物、食品、制药和农业的工业测试以及医疗成像。这个小型企业创新研究（SBIR）第一阶段项目提出开发一种新型的、高度集成的、低功耗的辐射计接收器，工作在183.31 GHz左右，靠近一条水蒸气吸收线。接收机结构的选择是为了提高辐射计的灵敏度、校准精度和可靠性，同时保持其重量、尺寸和功耗低。这项工作的目标是开发一种能够广泛观测天气的传感器。接收机相对容易组装、维修，生产成本低，特别是大批量生产。一期项目的重点是接收机设计的可行性研究。将设计主要的接收器组件并对其性能进行建模。预期的结果是整个接收机的初步设计和其操作参数的表征。

The broader impact/commercial potential of this project is in improving and simplifying weather observations from various platforms, such as an unmanned aircraft, small satellites in orbit, a buoy in the middle of the ocean or from the ground, even in a remote location. The targeted customer for the radiometer receiver is anyone who desires a more detailed, localized, short term forecast. Such customers include meteorological organizations, both private and governmental, operators of renewable energy plants ? onshore and offshore wind farms or solar power plants, future unmanned or robotic aircrafts that observe the atmosphere, military, and others. Sensors built with these receivers can also contribute to remote detection of in-flight icing danger in general aviation. Our sensor will simplify observations from small aircraft, piloted or unmanned, thus allowing new observations of clouds, their water or ice content, and the local thermodynamic status of the atmosphere. Such observations will thus improve scientific understanding of clouds and their representation in climate and Earth system models. More broadly, this project represents a new technological concept of sub terahertz receiver design and assembly. Users of sub terahertz receivers include airport security (body scanners), short range high bit rate communications, industrial testing of paper, polymer, food, pharmaceutical and agriculture, and medical imaging.This Small Business Innovation Research (SBIR) Phase I project proposes the development of a novel, highly integrated, low power consuming, radiometer receiver operating around 183.31 GHz, in the vicinity of a water vapor absorption line. The receiver architecture was chosen to improve radiometer sensitivity, calibration accuracy, and reliability, while keeping its weight, size, and power consumption low. The goal of the effort is to develop a sensor that would enable wide spread weather observations. The receiver would be relatively easy to assemble, repair and its production cost would be low, especially for large quantities. The Phase I project is focused on a feasibility study of the receiver design. The major receiver components will be designed and their performance modelled. The anticipated result is a preliminary design of the whole receiver and characterization of its operational parameters.
