"句芒"号卫星超光谱探测仪设计与系统验证
Design and verification of the spectrometer on"Gou Mang"satellite
摘要
Abstract
With the proposal of the Double Carbon target,the development of quantitative remote sensing technology for carbon monitoring is increasingly urgent.The detection of solar-induced fluorescence can be used as an important means to evaluate the actual photosynthesis effect of vegetation and the carbon cycle efficiency.This paper introduces the performance indicators,design scheme,system composition,verification results and in-orbit operation of the spectrometer on the"Gou Mang"satellite.The spectrometer is a precise optical instrument for solar-induced fluorescence detection.The system adopts a design scheme of pushbroom imaging and grating dispersion spectroscopy.After testing and verification,the spectral resolution is better than 0.3nm,and the ground pixel resolution reaches 1.5 km.Under typical input radiance conditions,the system SNR is better than 500,and all indicators meet or exceed the detection task requirements.It has high spectral resolution,high SNR and high stability detection capability.Its good performance will play an important role in vegetation monitoring and carbon cycle applications.关键词
