different story.

I've not heard of such capability before so I called our friendly local, and brand-new high tech, approach facility here in Indy to ask them about radar derived altitude. The answer was no, all they have is mode C capability.
As someone else commented, military facilities used to have PAR that could esentially derive altitude along a specific range, but I'm not sure those facilities are up and running any more.

I got in touch w/ some friends and learned that GCA is increasingly rare in the US,but is still used elsewhere in the world,and that civil A/C do use these approaches.

Last I knew Luke AFB had one at their Aux 1 field along with an ILS for
F-16 training. Eielson AFB in AK had one when I left their in '92 and
they would allow civil planes to fly it for practice with something like
100 ft AGL restriction flying over their runway.
