The large-scale SAR ship detection dataset-v1.0 (LS-SSDD-v1.0) was built on the Sentinel-1 satellite, including 30 large-scale SAR images. The large-scale images are collected from 15 original large-scene space-borne SAR images. The polarization modes include VV and VH, the imaging mode is IW and LS-SSDD-v1.0 has the characteristics of large-scale ocean observation, small ship detection, abundant pure backgrounds, fully automatic detection flow and numerous standardized research baselines. Fig. 1 is an example of a large-scale image in LS-SSDD-v1.0.

The large-scale image size of LS-SSDD-v1.0 is unified to 24000 × 16000 pixels, the format is a three-channel, 24-bit, grayscale, .JPG images, and the annotation format is a .XML format file. The annotation file records the target location information, in which the location information is composed of Xmin, Xmax, Ymin and Ymax. For an example of the annotation file, see the “LS-SSDD-v1.0 Usage Instruction”.
