摘要
研究了一种星载太阳同步轨道远紫外成像光谱仪,以满足对低层大气驱动力与电离层之间耦合作用探测的科学需求。仪器拟采用双侧向临边探测方法,对电离层中在远紫外波段产生昼夜不同特征辐射的各种粒子的光谱辐射强度进行探测,进而定量获取低层大气驱动力的影响。根据探测机理,进行了仪器系统观测方案设计、仪器性能参数与系统设计、原理样机系统集成、性能测试和地面辐射定标等研究,该研究为我国未来电离层远紫外成像光谱探测提供一种思路。
Abstract
A space-borne far ultraviolet imaging spectrometer working at the sun-synchronous orbit is studied, which is used to satisfy the scientific requirements of the connection and coupling detection between the low atmospheric driver and ionosphere. The instrument is designed to detect the spectral intensities of various particles in the ionosphere, which produce the characteristic radiation different at day and night in the far ultraviolet band, by the two-side lateral limb observation method. Then the influence of the low atmospheric driver is further acquired quantitatively. According to the detection mechanism, the observation scheme for instrument system is designed, the instrument performance parameters and system design, integration of prototype system, performance test, ground radiation calibration, and others are investigated. This research provides a new way in the future far ultraviolet imaging spectral observation of the ionosphere.
