EVOLVEMENT OF POLARIMETRIC TECHNOLOGY DETECTING ATMOSPHERE AND SONE CONSIDERATION OF ITS PROBLEMS

近年国际上偏振微波雷达探测大气研究有了重要进展,成为雷达气象学研究的新热点,并可能成为天气雷达发展的重要方向。介绍了微波圆偏振技术现状和双线偏振测量技术体制的重要进展,以及近年在气象应用中所获得的最新研究结果,展望了偏振探测技术的应用前景。进一步讨论了开展偏振探测技术研究所应考虑的有关偏振类型、实现体制、方案设计、产品算法和波段选择中的问题,对偏振探测技术研究具有参考价值。

In recent years the study of polarimetric technology for detecting atmosphere has made great progress, and become a popular aspect of radar meteorology. This paper presents detecting technology status of circular polarization and evolvement of dual-linear polarization, and new application to detecting atmosphere of polarimetric technology, and prospects future meteorological application of polarimetric detecting technology. At a more advanced stage, polarimetric basis, implement system, scheme designs, production method and wavelength selection are considered, being useful to the study of polarimetric technology detecting atmosphere.
