I had fun reading this -- the radio astronomy technique called VLBI (very long baseline interferometry) has a ton of overlap, but the jargon words are fairly different. There are plenty of differences: our telescopes are mostly on the surface of the Earth and don't move, VLBI isn't a radar so there's no waveform, etc.

The EHT black hole telescope is an example of VLBI.

Very similar. To the extent that when I’ve worked on synthetic aperture I have used ideas from radio astronomy.

And there’s a similar field of synthetic aperture ultrasound which is where I did a ton of work a decade ago.
