Paper Abstract

Based on the complex movement of satellite platform, we take the impacts on spectral imaging by pitch, roll and yaw into account. Then point spread matrix calculation principle is put forward, which takes transform the POS data into point spread matrix. According to this theory, we proposed the concept of pseudo cross-correlation to set up the model of spectral imaging degradation based on the pseudo cross-correlation, which combines the point spread matrix and original spectral data by the concept of pseudo cross-correlation. And in this method, the process of spectral imaging degradation is formed, which improve the existing problem of spectral imaging degradation based on the complex movement of satellite platform. The simulation results show that this kind of degradation theory is suitable for solving the problem of spectral imaging degradation based on the complex satellite platform movement completely.
