The broader impact/commercial potential of this project is in the improvement of atmospheric state observations from various platforms. This compact, integrated and ?plug and play? receiver design will make the existing observations more available, more economical, and will also enable previously unattainable observations of water vapor distributions within the atmosphere. This environmental sensor?s small size and low power requirements enables its deployment on various airborne, spaceborne or ground-based platforms, such as unmanned aerial aircraft, nanosatellites, ocean buoys, and remotely located ground-based instruments. One promising commercial application is private weather observing satellite constellations. It has been estimated that around 400 remote sensing nano/microsatellites will be launched worldwide between the years of 2016-2018. Water vapor and cloud observations are among the most important observations promising further understanding of weather events and to better synoptic or mesoscale forecasts. Improved atmospheric observations are directly related to increasingly accurate and useful weather forecasts. The benefits are expected to extend widely across the economy. Meteorologists point to more accurate and rapidly refreshed atmospheric observations as one of the necessities for the continuous improvements in weather forecasting, understanding of the atmospheric physics and climate.This Small Business Innovation Research (SBIR) Phase 2 project will complete the design and build a fully functional prototype of a very compact, direct detection radiometer receiver, operating in the vicinity of the 183 GHz water vapor absorption line. All the receiver components will be designed and evaluated, including a noise source, detectors, filters, Monolithic Microwave Integrated circuits and others, first as individual parts and then within the assembly. A novel receiver architecture and integration of all components into one assembly allow for a drastic reduction in the receiver size and reduction of its power consumption, while improving its observational capabilities and stability. There are several aspects of the proposed effort that are unique and would provide profound advances in ultra-compact microwave radiometry. The receiver is expected to consume less than 0.5 Watt of power and weigh around 100 grams, with a continuous two-point calibration capability at its input.

该项目更广泛的影响/商业潜力在于改进了各种平台的大气状态观测。这款紧凑、集成、即插即用的？接收器的设计将使现有的观测更方便、更经济，还将使以前无法实现的大气中水蒸气分布的观测成为可能。这种环境传感器？S，体积小，功耗要求低，可以部署在各种机载、星载或地面平台上，如无人机、纳米卫星、海洋浮标和远程地面仪器。一个有前景的商业应用是私人气象观测卫星星座。据估计，在2016-2018年期间，全世界将发射大约400颗遥感纳米/微型卫星。水蒸气和云层观测是最重要的观测之一，有望进一步了解天气事件和更好地进行天气或中尺度预报。大气观测的改进与日益准确和有用的天气预报直接相关。预计这些好处将广泛延伸到整个经济领域。气象学家指出，更准确和快速更新的大气观测是不断改进天气预报、了解大气物理和气候的必要条件之一。这个小型企业创新研究(SBIR)第二阶段项目将完成非常紧凑、直接探测的辐射计接收器的设计和全功能原型，工作在183 GHz水蒸气吸收线附近。将设计和评估所有接收器组件，包括噪声源、探测器、过滤器、单片微波集成电路和其他组件，首先作为单独的部件，然后在组件内。一种新颖的接收器体系结构和将所有组件集成到一个组件中，可以大幅减小接收器的尺寸和功耗，同时提高其观测能力和稳定性。拟议的努力有几个方面是独一无二的，将在超紧凑型微波辐射测量方面提供深刻的进展。该接收器的功耗预计不到0.5瓦，重量约为100克，其输入端具有连续的两点校准能力。
