Yes,HRTF is part of my problem.Without any noise or reverberation,I can

to each location in 3d,which tracking model is used in this situation?
Your situation sounds like 'bearings-only' and 'target motion
analysis'. If you have a single source and good signal strength, there
are papers back to the '70s and '80s that discuss track formation. If
you add multiple sources to track and lowered signal to noise
conditions you need more complicated algorithms such as 'probabilistic
data association filter' (PDAF). I would sugest that you look at
something like the IEEE Xplore site and search on these terms in
Trans. on AES. Look at abstracts. If they are more complicated than
you are interested in, track back through the referenced documents to
find simpler cases, follow through the referencing documents to find
more developed applications. I think you will find that Google will
lead to the same path.
Good Luck!
