space target;low snr; star catalog

This dataset is image data generated by matlab simulation based on star catalog, imaging process analysis, and space target characterization. There are three signal-to-noise ratios in the dataset, the signal-to-noise ratios are 0.7, 1, and 1.5.There are 10 groups of data under each signal-to-noise ratio, and each group of data contains 10 images. It can be used for research such as target detection and tracking.
