In order to meet the data requirements in the development of space-based optical observation platform and simulate the debris motion tailing phenomenon in space-based optical observation images, a simulation algorithm of debris motion tailing in space-based optical observation images is proposed. Firstly, the imaging principle of CCD sensor is analyzed, and the simulation process of space-based optical observation image is designed. Secondly, the causes of space debris motion tailing are described. Finally, the imaging angular velocity of space debris is deduced, and the simulation method of space debris motion tailing is given. Simulation results show that the algorithm can truly simulate the motion tailing of space debris, which is helpful to the development of space-based optical observation platform.
In order to meet the data requirements in the development of space-based optical observation platform and improve the simulation accuracy of space debris tailing, a simulation method of space-based optical observation image based on two-line-elements is proposed. Firstly, by analyzing the imaging process of real image, the simulation process of space-based optical observation image is designed, and the calculation method of each process is given. Then, the space debris tailing of real images is analyzed, and the limitations of the traditional space debris tailing simulation algorithm are obtained. Finally, combined with two-line-elements, a space debris tailing simulation algorithm suitable for long exposure time is proposed. The simulation results show that the algorithm not only ensures the fidelity of imaging, but also simulates the tailing of space debris with high precision, which is of great significance to the development of space-based optical observation platform.
