Abstract
The detection and recognition for the attitude of space target is a technical problem and research focus. In this paper the attitude inversion technique of space target was explored based scattering spectroscopy. The scattering spectra of the space shuttle model instead of space target in the laboratory were detected in 0~360° direction at 10° intervals, and the spectral database of the one-dimensional rotating space shuttle model was established. Based on spectral bidirectional reflectance distribution function (SBRDF) theoretical model, the experimental data were compared with the data in the database using residual as a reference. When the rotation angle of the space shuttle model was 8°, 68°, 293°, the angle corresponding to the minimum residual was 10°, 70°, 290°. The results indicated that the inversion of rotation angle of the space shuttle model was achieved and inversion accuracy is better than 5°. According to the redundancy of spectral data (700 effective bands), if the angle interval of spectral data was reduced, the attitude inversion of space target of higher angle accuracy can be achieved. In this paper, for the first time the one-dimensional attitude inversion of the space shuttle model was realized based on the scattering spectrum, and the correlation between scattering spectra and attitude was confirmed. This research is helpful to the application of spectroscopy in the field of the attitude inversion of space target.
