They have two integrated software suites that synthesize data across multiple vessels, aircraft and other datapoints and display them for all members of the suite. They've been attempting to integrate what they have even closer. So if enough sensors agree that there's a "something" at 12nm traveling at 3000kt, aircraft within 2nm of the signal trace are given a visual indicator of that "something."
The whole controversy is over the creation of false bogeys. If I had to guess? Someone is pushing the UFO narrative in order to make Raytheon look bad. Because obviously you can't publicly say "Raytheon's system is so terrible at integrating that it's showing us tictacs traveling at 20,000 mph" without violating a whole lot of security protocols.
