from the article, a description of "Cooperative Engagement Capability (CEC)" system:
>What most don't realize is that the Nimitz Carrier Strike Group wasn't just equipped with some of the most advanced sensors the world had to offer, but that it also had hands-down the most advanced networking and computer processing capability of any such system. Dubbed Cooperative Engagement Capability (CEC), this integrated air defense system architecture was just being fielded on a Strike Group level for the first time aboard Nimitz and the rest of its flotilla.
>Our readers are familiar with CEC and the follow-on iterations that have come since, as we talk about the concepts behind them often. At its very basic level, it uses the Strike Group's diverse and powerful surveillance sensors, including the SPY-1 radars on Aegis Combat System-equipped cruisers and destroyers, as well as the E-2C Hawkeye's radar picture from on high, and fuses that information into a common 'picture' via data-links and advanced computer processing. This, in turn, provides very high fidelity 'tracks' of targets thanks to telemetry from various sensors operating at different bands and looking at the same target from different aspects and at different ranges.
>Whereas a stealthy aircraft or one employing electronic warfare may start to disappear on a cruiser's radar as it is viewing the aircraft from the surface of the Earth and from one angle, it may still be very solid on the E-2 Hawkeye's radar that is orbiting at 25,000 feet and a hundred miles away from the cruiser. With CEC, the target will remain steady on both platform's CEC enabled screens as they are seeing fused data from both sources and likely many others as well.
So these 3 paragraphs state:
1. Instead of each platform (plane, boat, ...) relying on only it's own sensors, the platform sensors (radar, IR ...) are automatically sharing their observations across platforms by data links, fusing them into one scene, such that each platform has the eyes and ears of all platforms combined. Obviously only 1 sensor needs to malfunction or misinterpret signals such that they are gossiped across platforms where the operators seemingly "independently" observe the imagination, i.e. data fusion potentially triggers common hallucinations. Regarding the pilots, navigators: I speculate for example this could have been the augmented reality HUD overlay showing the IR feed...
2. the system was "just being fielded", increasing the odds of initial wrinkles in the data fusion system.
3. again the system was "just being fielded", increasing the odds of human operators misinterpreting their display systems as depicting what the sensors of their platform are sensing, since before introduction of sensor fusion this would have always been the case. Human operators would thus more easily fail to realize that their "independent observations" were not in fact independent at all.
