The imaging matching model of the digital domain time-delay integral (TDI) complementary metal-oxide-semiconductor (CMOS) sensor under the staring gesture is designed in order to realize high-resolution staring imaging, attitude which satellite changes relative to orbital coordinate system staring on satellite staring tracing imaging is derived. The coordinate transformation method is used to real-time compute the time of the line transfer process in the staring, the method of Monte Carlo is used to statistically calculate the influence of imaging under the satellite′s attitude point precision and stability in the mode of staring imaging. The TDI CMOS prototype and the minitype three-axis air bearing table constructed for attitude control are used to simulate the digital domain TDI CMOS staring imaging. Experimental results show that the satellite′s attitude control accuracy will cause the vertical image velocity mismatch and the residual image of transverse matching in the process of imaging. The higher imaging integral series is, the greater the signal-to-noise ratio (SNR) of the image will be. Integral series increase has a higher requirements to the satellite attitude. The control accuracy of the attitude angles and attitude angular velocity of the staring imaging simulation platform is better than 0.05° and 0.005°/s, the integral series 48 can meet the image-quality requirement.
