They are radar images from synthetic aperture: https://www.youtube.com/watch?v=u2bUKEi9It4

Synthetic aperture radar [1][2] uses this principle. In that case the imaging system is fixed on a moving aircraft or satellite.

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.

A major difference here is that SAR uses phase information, whereas to my knowledge optical techniques are not doing that.

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).

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 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.
