I did a PCA using 12 Sentinel-1 images, but the eigenvalues of each image on the PC1 are a bit confusing to me. They are:
My doubt is, shouldn’t at least one of these values be greater than ~0.8? According to some papers, there is always at least one or two images that is “highlighted” in the first PC with values close to 1, but on my research there is not.
Thanks a lot!
