10m？还是20*22m？

Sentinel-1 SAR GRD的分辨率为10m，基本上是常识了https://developers.google.com/earth-engine/datasets/catalog/COPERNICUS_S1_GRD#descriptionhttps://developers.google.com/earth-engine/datasets/catalog/COPERNICUS_S1_GRD#description

 但是有论文提到Sentinel-1 SAR GRD的分辨率为20*22m

Resolution和Pixel Spacing

Resolution：分辨率，衡量系统区分相邻目标的能力，区分两个目标的能力

Pixel Spacing：像素间距，图像中相邻像素之间的距离
