Sonar for underground imaging?
I thought there was a type of sonar that could be used for underground imaging, but I saw nothing about this in the article. I'm not talking about Ground-penetrating radar, because that uses radio waves. Does anyone have any information on this? A simple Web search turned up nothing useful.

- Reflection seismology, but not the easiest article to find under that name. Andy Dingley (talk) 22:05, 17 May 2017 (UTC)
