Swarmies and Iris

I see NASA Swarmie type Rovers have Arduino ultra-sonic sensors all over the place. What sensors would be actually be used on the Moon?

I know the Moon has an atmosphere, mostly half a meter above the regolith and below. But the atmosphere is so sparse I don't think one could pick out reflected sound waves above ambient noise. Perhaps I should relook at just how dense the Lunar atmosphere is.
