摘要
电离层对人类活动影响重大,涉及天气、通讯、军事应用和卫星运行等许多方面.电离层中各种粒子的发光辐射特性,特别是远紫外辐射特性,是电离层、热层和极光带等高层大气的物理化学信息重要来源.对电离层进行探测,主要是通过最先进的光谱成像技术对远紫外波段进行研究,提供充足的电离层分布的光谱信息和空间信息,建立精确的电离层模型.本文主要阐述了电离层远紫外波段光谱成像技术的发展和趋势,指出了影响这种技术的关键因素,即光学系统和探测器,分析了我国相关技术的薄弱环节.并结合我国目前的研制水平和技术,提出了发展星载电离层探测成像光谱技术的建议.
he ionosphere affects human activity in many regions so much, such as weather,communication,military application and near space satellite in orbit.The characteristics of luminous radiation of different particles in the ionosphere,especially the characteristics of radiation in far ultraviolet,contain fundamental chemical and physical information about upper atmosphere,ionosphere,thermosphere and aurora zone.The advanced spectrum imaging techniques applying to the ionosphere observation can supply enough space and spectrum information of the distribution of ionosphere and precise model.In the paper,the development of far ultraviolet spectrum imaging techniques is reviewed.The key aspects of this technology are optical system and detector which is our disadvantages.A proposal for developing our spectrum imaging technology of space-based ionosphere measurement is presented.
