NORAD said after the last balloon they modeled it and recalibrated their signal filtering to lower the thresholds (full transparency: I know what those words mean when string together, but I’m no expert and have 0 functional knowledge of what that means wrt NORAD).

Now that they’ve said that, I’m actually more concerned and it raises more questions than it answers. Perspective of some retired NORAD employee would be very welcome




I saw comment that said they removed the speed gate filter. I think that means filter was removing slowly moving contacts. By removing the filter, they saw balloons and the hovering maybe-balloon objects.
