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. The instability of the satellite platform will seriously affect the imaging quality of the imaging system. Two kinds of degradation models of the imaging spectrum are established for the degradation of the imaging quality caused by the vibration of the platform by interferometric and dispersion imaging spectrometers. The proposed spectral differential The dynamic imaging degeneration simulation method takes into account the complex influence of complex vibration.By proposing the concept of average doping ratio, a bridge between the satellite platform motion parameters and the effects of spectral imaging is established, and the quantitative relationship between the two is derived Degradation simulation was carried out using the spectra of typical and simulated terrain as an example. Degradation results show that the effects of pitch and roll in the platform vibration are larger than the yaw, and not only affect the spatial resolution but also cause spectral distortion, Larger is the rich variety of land area.
