SAR is similar but not the same since there you're super-resolving in time rather than space. Also in that instance it's just conventional MISR since you're not driving the imaging system (more information is being passively collected as the targets passes).
I think it’s more useful to think in terms of how well sampled the observations are relative to the size of the output space. SISR is very undersampled, and MISR is oversampled. SAR reconstruction techniques can fall in either bucket.
SAR is similar to the video technique mentioned, agree it's not quite the same but if underlying assumptions hold still more estimate than "guess".
I think in general satellite imaging is a good place to look for such implementations, since they have a naturally and predictably moving imaging system.
