Space/Science » in reply to yes, you get a good measure of surface "roughness" from RADAR.

re: RADAR.

I was thinking along the lines of the echoes being "softer" somehow from a liquid than from a solid, above and beyond the smoothness. Don't know if that's true or not.

Boy, how old are you that you still capitalize "radar" as though it still was the letters from RAdio Detection And Ranging? ;)

Of course, I still remember what 3M stood for.
