Magic sauce ;-)). The beamformer has to shape it’s beams to get the separation. I guess the results are not predictable and may be very different at different locations.

Same for rx. The key word here is diversity. There are lots of different ways to get diversity. Which of these cambium is able to exploit with the medusa I'm still not 100% clear on. At least direction for sure. On Nov 2, 2016 3:51 AM, "Kurt Fankhauser" <[email protected] <mailto:[email protected]> > wrote: how many arrays are in in? 7 or 14?
