According to the radiation intensity of the spaced-target, the SNR and detection distance of the spaced target of visible light has been study and analyzed. The relationship between SNR, detection distance and the size of the spaced-target, the reflectance, observed phase angle, as well as the entrance pupil area has been obtained. The specific formula of the detection distance of the spaced-target of detection of the visible light detection system is given. And key indicators that impact the detection distance of spaced target of visible light have been analyzed. The study provides a theoretical basis for the performance of the future space-target detection system. |
