This paper is concerned with the potentials and limits of super-resolution and super-location techniques of decametric SAR images. Firstly, the theoretical limits of super-resolution are studied and the link between super-resolution and super-location is highlighting. Secondly, two approaches have been derived from the literature: super-resolution techniques with a single SAR complex image and a super-resolution method based on multiple spectrally shifted images. Each approach is evaluated on real data and a new method extending single image techniques to multiple images is proposed.
