title: [Simulation and analysis of interference imaging spectrometer influenced by satellite vibration].
abstract: During the spectral imaging course of interference imaging spectrometers, satellite platform's instability will bring serious impact on the imaging quality. Based on studying the degradation mechanism, a differential dynamic imaging simulation method is proposed here to simulate the process of spectral imaging degradation. And in this method, the mean ratio of doping is put forward, which combines the satellite motion parameters with the impacts on spectral imaging. And the quantitative relationship between them is deduced in detail With environmental resources satellite as an example, the degraded result is simulated, showing that the vibration affects the spectral imaging not only in the spatial resolution but also in spectrum, with the region of rich species having more serious influence. And through the simulation and analysis, the satellite attitudes' stability is requested accurately, below which the impacts of satellite vibration on spectral imaging should be significant and it's necessary to adopt corresponding compensation measures.
