Well, yes, it does...
, my point too.
It was Graybeard, who suggested that professional "usage" tends to refer to FMCW type radar altimeters as "radio altimeters" and pulse type radar altimeters as "radar altimeters". If that's so, I have no issue with that. Just a matter of accepted terminology, nothing more.
Both shorten to "rad alt" anyway.... to distinguish them from "baro alt".
