| 英文摘要 | all-day star sensor makes it possible to observe stars in all-day time in the atmosphere. but the detecting performance is influenced by atmospheric turbulence. according to the characteristic of turbulence in long-exposure model, the modulation transfer function, point spread function and encircled power of the imaging system have been analyzed. combined with typical star sensor optical system, the signal to noise ratio and the detectable stellar magnitude limit affected by turbulence have been calculated. the result shows the ratio of aperture diameter to atmospheric coherence length is main basis for the evaluation of the impact of turbulence. in condition of medium turbulence in day time, signal to noise ratio of the star sensor with diameter 120mm will drop about 4db at most in typical work environment, and the detectable stellar limit will drop 1 magnitude. © 2016 spie. |
