I'm working on wideband multichannel recordings made with 4 hydrophones
mounted on a 3D structure; something similar to a tetrahedron, with 3
hydrophones mounted on an horizontal plane and the fourth higher then the
other 3. The spacing among the phones is roughly 2 meters.
I'm searching an algorithm to calculate the direction (bearing and
elevation) of an acoustic source given the time delays I measure among the
four hydrophones and their 3D coordinates.
Any hint will be much appreciated!
