Space Target Optical Imaging Simulation in Space-based Passive Optical Detection System

This dataset comprises deep space target observation data generated by the proposed simulation algorithm under space-based passive optical long-distance detection scenarios. It includes three types of illumination backgrounds: strong light spot background, non-uniform strong light background, and no illumination background. For each illumination background, multiple sets of target motion sequence images with different signal-to-noise ratios under various observation conditions were generated. Each set contains 3,000 images with a resolution of 500×500 pixels. The JSON files store the ground truth of target positions for each dataset, and the true trajectories of the targets have also been generated.
