Images taken by the Sentinel-1 satellite may have black edges. This is because Sentinel-1's synthetic aperture radar (SAR) sensor needs to scan the ground with multiple radar beams to obtain higher-resolution images when taking images. However, the images taken by each beam overlap, and if not processed, black edges will appear.
In order to solve this problem, the Sentinel-1 satellite used Multi-Temporal SAR technology to stitch and process the images of different beams, remove black edges and increase the clarity and quality of the image.
If the image of Sentinel 1 has black borders, it may be due to improper data processing or sensor abnormalities. At this point, you can try to reprocess the data or check the sensor status to solve this problem.
