Other articles have reported they've changed how they're filtering radar signals, which could partially explain why more real objects are being found now, but would also result in additional false positives.
> The incursions in the past week have changed how analysts receive and interpret information from radars and sensors, a U.S. official said Saturday, partly addressing a key question of why so many objects have recently surfaced.
> The official, speaking on the condition of anonymity because of the sensitivity of the issue, said that sensory equipment absorbs a lot of raw data, and filters are used so humans and machines can make sense of what is collected. But that process always runs the risk of leaving out something important, the official said.
> “We basically opened the filters,” the official added

- thrill 4y agoI suspect that when the Commander-in-Chief starts asking why things aren't being detected sooner than after penetrating the coastline, then any previous filtering for "quality", as in meeting certain velocity parameters, whether being not too slow, or not "too fast" - i.e. a momentary reflection in two spots now gets interpreted as a high velocity paint instead of the previous two indeterminate and fleeting radar returns that would have been ignored - well, that filter gets turned way down and we end up chasing a lot of ghosts.
