Having a hard time with the sed/echo commands?

Hello,

well what I'm trying to do is to remove underscores from filenames and leaving empty spaces instead:
Code:
arturas@Universe:/windows/Center/training$ ls
big_file  failas su shudu
arturas@Universe:/windows/Center/training$ a=big_file
arturas@Universe:/windows/Center/training$ mv $a `echo $a | sed 's/_/\\ /g'`
mv: target `file' is not a directory
arturas@Universe:/windows/Center/training$

I've tried a few more variations, but still, I think this one's the most accurate, others do the same though.

So, can anybody help me here? Thanks.
