That's what they called it in the Star Blazers dub, so it's an accurate translation.

It's not often that Japanese can translate so directly into English like this, but it works.
Ha/nami = wave (thus "tsunami"; tidal wave)
Dou/ugo(ku) = motion, movement
Hou = cannon

Guh... awkward trying to explain this in Romaji (but alas, this board doesn't allow for Japanese script)
