[quote=Anonymous][quote=Anonymous][quote=Anonymous]Apparently the reason these things weren’t detected years earlier (or ever) was because the software that analyzes radar data has settings (called “gates”) that essentially filter out things that don’t meet certain criteria: airspeed, trajectories, etc). The program is looking for radar returns that are consistent with that of an aircraft or of a rocket or missile. It filters everything else out that doesn’t fit that profile. So a slow moving balloon and it’s payload, being nearly “motionless” compared to an aircraft or missile, is just seen as “noise” by the software, and is filtered out. Apparently the NORAD IT folks have rewritten some code over the last week after the first balloon incident, and now suddenly are spotting these things now. But this has clearly been going on for probably years, maybe even decades. And the radar software was filtering it out because it didn’t fit a target profile that had been programmed. And China clearly knew about this, and exploited it to great effect. [/quote] Wow, that's a pretty big oversight isn't it? It's rather naive of the military to assume that only aircraft and missiles are concerns so filter out everything slow moving. If other nations know that your software does this (and evidently they were aware) then all they need to do is create craft that doesn't behave in the way your software is expecting enemy incursions to appear. Which seems to be what they've done. You're looking for airplanes? We'll make a balloon.[/quote]No, they knew. A sharp reporter asked since Biden was aware of these balloons since last year, why didn't they adjust the gateways sooner? They didn't want to find them for whatever reason.[/quote]
