1) unfortunately no. Longwave radars as Lichtenstein are quite different than centimetric radars. Antennas for metric waves cannot be made big enough to shape beam into narrow cone and still be carried by a plane, so radar "sees" everything around and merges it into a lines on display. That means whole surrounding must be included in process, but direction to any point on ground does not have to be kept, sums of returned echoes can be updated quite lazily and only thing to draw are oscilloscope lines.
Centimetric radar has fairly narrow beam which is rotated around by moving antenna and usually can display bright point to any place on its screen. That makes three challenges, how to extract landscape geometry in chosen direction fast (hit by very fast moving beam), how to model screen which can contain anything and how to do afterglow which was very important to make information useful for user.
I'm afraid my explanation of differences between radar principles was very short, simplified and not much useful, if you want to know more, googling for lobe switched radars will be certainly better
.
Centimetric radars are on priority list, but still in phase of searching for an algorithm. Modelling H2S would create additional trouble - aircraft for it. It would need heavy bomber (maybe with exception of some pathfinder mosquito variant) and those are
very time consuming to model, especially cockpits.
2) still open question, probably will be included
