This looks interesting.

"... The imaging system, developed in cooperation with Bellevue-based OptiNav, combines several tricks of the acoustic trade. It starts with a square metal plate, about 2 feet wide, which is dotted with an array of 40 tiny digital microphones."
Aha, so that's the secret, it uses DIGITAL microphones. 😀

Using digital mics could be a real enabler here.... if they have daisy-chainable serial interfaces, that would make connecting an array hugely easier than making mixers and separate gain controls for 40 separate analog signals. You'd instead just have a big digital stream to read in and operate on with DSP.
