Satellite dynamic imaging mode can realize satellite imaging in a large-angle fast maneuvering process, meeting the diversified, customized and refined requirements of remote sensing observation. In this work, the basic principle of ground experimental system for dynamic imaging is analyzed, and a set of ground experimental verification system for dynamic imaging mode is built in the laboratory. The system uses a high-precision, high-stability dynamic air flotation target and a camera integration time adjustment method based on an external trigger signal. The relationship between the image quality and light intensity, the relationship between the image quality and the integral series of the camera detector and the maneuvering velocity of the satellite are studied. A dynamic imaging experiment with a custom motion curve is carried out. The results show that in the linear region of the camera detector, the range of the image dynamic modulation transfer function (MTF) value obtained with different maneuvering angular velocities and detector integration series is 0.0918-0.1054, which meets the requirements of engineering applications (near 0.1), and the MTF value has nothing to do with maneuvering angular velocity and detector series. In the dynamic imaging experiment, the system runs stably, and the dynamic MTF value is between 0.1015±0.0098.
