The Study of Dynamic SNR Model on the Space-Based Visible Camera
This paper put forward a dynamic signal-to-noise ratio (SNR) model based on the space-based visible camera (SBV). Firstly, the characteristics of SBV are reviewed and the performance and key technologies of SBV are analyzed in the paper. Secondly, the SBVs space targets detection signal are discussed. The visible light scattering characteristic of space-based objects is set up. Thirdly, the external and internal noise models of SBV are built. On basis of analyzing the SBVs space targets detection signal and detection noise, the dynamic SNR model is derived and the main factors which influenced the system SNR are analyzed.
