摘要

卫星平台不稳定性将严重影响光谱成像质量, 针对干涉型和色散型成像光谱仪受平台振动而产生的成像质量退化影响进行机理研究和仿真, 建立了两类成像光谱的退化模型. 提出的光谱微分动态成像退化仿真方法, 考虑了复杂振动的综合影响. 通过提出平均掺杂比的概念, 建立起卫星平台运动参数与光谱成像影响之间的桥梁, 详细推导了这两者间的定量关系. 并以典型光谱和模拟地物光谱为例进行了退化仿真, 退化结果表明平台振动中俯仰和侧滚的影响比偏航大, 而且不仅会影响空间分辨率, 还会带来光谱失真, 而影响较大的是地物种类较丰富的区域.

Abstract

Instability of satellite platform will seriously affect the quality of spectral imaging. The degradation mechanism of interferential and dispersive imaging spectrometers caused by satellite vibrations is studied in this paper. A simulation algorithm of degradation based on differential dynamic spectral imaging is presented. And the concept of mean mixing ratio (MMR) is proposed, which builds the bridge between the parameters of satellite vibration and the influences on spectral imaging. The quantitative relationship between them is also deduced in detail. Spectral degradation results are simulated by taking the typical spectra and the generated spectrums of surface features as the ideal original data. Simulation results show that the effects caused by pitch and roll are much greater than that by yaw, and the vibrations affect not only spatial resolution but also spectrum, and the regions of rich species are influenced seriously.
