【摘要】 本文介绍了我国正在研制的新一代地球同步轨道气象卫星的主要有效载荷之一一“多通道扫描成像辐射计”的性能指标及其相对于风云二号地球同步轨道气象卫星“多通道扫描成像辐射计”的主要性能比较,介绍了仪器的组成、仪器工作原理和工作方式。并着重及绍了仪器研制过程中主要技术难点一一角秒级控制精度的二维扫描技术及其扫描镜运动对卫星姿态稳定度的扰动和对图像配准的影响、太阳的直射对仪器性能的影响、仪器的长寿命技术等;并探讨了关键技术的主要解决途径。更多还原

【Abstract】 This paper introduces one of the primary instruments , multiple channel scanning imager , of our being researched new-generation geostationary meteorological satellite, “FY-4”. The two imager’s primary differences of their characteristics are introduced .it is also introduced the buildups, the opoperation principle and the operation mode of the imager. And it is emphasized the primary difficulties on manufacturing technique of the imager, which are two-dimension scanning control technology of arcsec precision, the interference. Of satellite pointing from scan mirror motion and the performance change of the imager from the solar. The way to solve the primary difficulties has been discussed.更多还原
