英文摘要	In order to achieve high sensitivity space target imaging under the condition of close distance, the inertial space tracking and pointing model, terminal sliding mode control method which stabilize the image, imaging frequency independent matching technology were designed to achieve space target stable pointed and high signal-to-noise ratio imaging by high sensitivity CMOS camera. Finally, satellite three axis attitude control simulation system, space-based LED target display system and high sensitivity CMOS camera imaging system were used to simulate attitude control in inertial space tracking and stable point, and then high sensitivity imaging was tested in and out field. The results show that when the attitude of stabilize imaging is better than 0.02 and 0.001 5 ()/s in the process of the stability of the inertial space target pointing, high SNR image which is 19 dB can obtain in 10 ms exposure time; By using the GSENSE400 CMOS camera with F number of 10, out field experiment which has object distance about 20 km can obtain high SNR image more than 18 dB under the condition of low illumination about 0.05 lx and the exposure time about 10 ms. 2018, Science Press.
