Someone also pointed out that it's not clear whether this will be used for bearing ambiguity resolution or not. It might be, however, that improved processing might make phase differences that were previously not measurable measurable. It's hard to say, though.

.As far as range estimates, no idea here, as you said, range estimates are probably a bit trickier, and my recollection of advanced geometry and signal processing is too elementary/old.

It's called a hyperbolic fix. With two arrays you can't nail it down to a single point, but you can narrow it down to a range of possible points, from which you might be able to use other things to pick one.
