| 摘 要： | 人类社会的发展与气象观测密不可分，通过气象卫星观测气象是气象预报的重要手段。气象卫星主要分为极轨气象卫星和静止气象卫星两类。辐射成像仪一般是各类气象卫星的核心载荷，用于获取目标不同光谱波段的辐射数据。卫星气象是指对气象卫星获取的辐射数据进行分析处理，利用分析结果进行气象和气候预报。本文重点介绍了中国最新研制发射的第二代地球静止气象卫星--风云四号辐射成像仪的性能和技术特点，并介绍了辐射成像仪数据产品在卫星气象中的应用。

| Abstract: | The development of human society is inextricably linked with meteorology. Observation from meteorological satellite is an important means of meteorological forecasting. Meteorological satellite can be in polar orbits and geostationary orbit. Radiometer imager is typically the core payloads of meteorological satellite and makes use of the multi-spectra results to carry out meteorological and climate forecasts. This article focuses on the performance and technicalcharacteristics of the China’s newly developed and launched second-generation geostationary meteorological satellite FY-4 radiometer imager, and introducs the application of its data products in satellite meteorology. |
