This Small Business Innovation Research (SBIR) Phase I project proposes the development of a universal single-channel polarimetric receiver. A novel polarization measurement technique based on a spinning phase plate makes it possible to measure all four Stokes parameters of the incoming radiation with the use of one receiving channel only, while the conventional technique requires at least three channels for the same purpose. The major application of the proposed device is the in-flight detection of clouds that pose icing hazard. Measurement of the Stokes parameters of the radiation emitted by(radiometry) or reflected from (radar) these clouds proved to be useful for the determination of their potential danger. The device can operate as both a stand-alone radiometer and as the receiver of a radar system.The proposed polarimetric receiver is compact, capable of detecting icing conditions with excellent sensitivity and resolution, and manufacturable within existing infrastructure.There is an urgent need for such a low-cost and high-performance product for detecting potentially hazardous clouds along the flight paths, especially for helicopters, commercial commuter aircraft, and light, private, unpressurized aircraft.

这个小企业创新研究（SBIR）第一阶段项目提出了一个通用的单通道极化接收机的发展。一种基于旋转相位板的偏振测量新技术，可以用一个接收通道测量入射光的全部四个斯托克斯参量，而传统的偏振测量方法需要至少三个接收通道。该装置的主要应用是在飞行中探测构成结冰危险的云。对这些云发射的（辐射测量）或反射的（雷达）辐射的斯托克斯参数进行测量，证明有助于确定其潜在危险。该装置既可以作为独立的辐射计工作，也可以作为雷达系统的接收机工作。所提出的偏振接收机结构紧凑，能够以优异的灵敏度和分辨率探测结冰条件，并且可以在现有的基础设施内制造。迫切需要这样一种低成本和高性能的产品，用于探测飞行路径上的潜在危险云沿着，特别是直升机，商用通勤飞机和轻型私人非增压飞机。
