英文摘要	Achieving super-wide coverage for high-resolution cameras is difficult. To address this difficulty, this study designs a cone-pendulum scanning integrated imaging mode. First, by analyzing the principle of cone-pendulum scanning integrated imaging, a cone-pendulum scanning integrated imaging model was established. Then, the optimal ground trajectory model was designed, and the relationship between the orbital velocity, angular velocity of the platform rotation, and angular velocity of the pendulum scanning rotation was analyzed. Simultaneously, based on the ground trajectory, a calculation scheme of exposure time and frame frequency was provided. Finally, MATLAB was used to perform simulations, and the ground coverage width and ground pixel resolution were analyzed. The results show that when the orbital altitude is 500 km, pixel size is 2.5 m, focal length is 360 mm, and pixel number is 5 1205 120, then the camera installation angle is 30, number of frames of pendulum scanning imaging is 10, ground coverage width is 1 105.7 km, which is 31.1 times that of the image sub-satellite point push scanning imaging, and ground sample distance (GSD) is less than 6.4 m. The cone-pendulum integrated imaging mode can completely cover the ground target and considerably increase the width for specific resolutions. 2021, Science Press. All right reserved.
