ChrLzs Posted December 9, 2021 #51 Share Posted December 9, 2021 While we await Phantom's selection, I will, as a gesture of good faith, address what he says in the notes above each video. I won't go into full detail, just enough to refute the claims at what might be termed "Beginner's Guide" levels. 9 hours ago, Phantom309 said: I could find nothing from anyone to discount the FLIR footage. First up, I would point out that no-one here is trying to "discount the FLIR footage". As far as I can see, no-one has called it fake. I'm certainly not calling it fake, nor am I discounting it. What I am discounting is how this footage is being (mis)used by some to suggest something it does NOT show. The problem here is that the FLIR footage is being used to support claims of either groundbreaking capabilities or non-terrestrial characteristics. It is being misinterpreted, either deliberately or through a lack of knowledge of how the equipment works. In order to properly interpret the imagery, you need to understand: IR (thermal) imaging Optics and 'Zoom' How tracking works How the alt-azimuth Gimbal Tracking Mount works How/why that 'GTM' gains and loses 'lock' How the FLIR system gets a 'range' (or not) and how it may be linked to radar What the indicators on screen show (or don't show) What the scene should look like when tracking known / mundane things like a distant aircraft or target balloon or seabird The concept of relative and angular velocities and how calculations can or cannot be made (remembering that both the camera platform and the subject are both moving in different directions and velocities in 3D space (pitch/roll and yaw) *and* the camera is also panning on 3 axes as it tries to track) All of this movement of course makes the background apparently move at high speed also. It's all relative...... There's more, but that's just a start. Anyway, the fact that you couldn't find anything could suggest any of the following: you're not very good at using a search engine you're not very good at determining a source that is knowledgeable, and not in it for moneymaking, trolling or gathering clicks you did find stuff - but elected to not show it as it was far too complicated (see above for why..) you did find stuff - but didn't even look at it (for fear you might learn something?) there isn't any information out there, where the footage is analysed by people who actually know about all those things I listed above, and more. Now I have to point out that I know the last one is not true. I'll prove that in a little while. And all of these videos have been looked at right here at UM, as well. 9 hours ago, Phantom309 said: From all indications it was operating normally. Yes, I agree. Indeed, one of them was quite impressive at picking up a small distant object that could easily have been missed. Well done Raytheon. Although I'd have to observe that the optical side of your system isn't all that good, and you really need to work on the horrible blooming effects. More about that later, maybe. 9 hours ago, Phantom309 said: I'll include this link from an ex-fighter jock who evaluated the videos. 'Fighter Jocks' are not automatically good at using this equipment. They have much to learn and at least one of these videos (all?) was taken during training. Also, 'jocks' don't usually get into the vagaries of working out velocities and ranges and the like - there are WAY too many traps. Remember that ATFLIR is an aid to track (and if close enough, identify) potential threats, at which missiles and other things can then be thrown.. Quote He makes no conclusions on what the objects were Umm, right. Probably a wise move. I presume as you didn't mention anything, he doesn't do any calculations, either. Probably best. Anyway, that's enough for a start ... more when I have time. 1 2 Top Link to comment Share on other sites More sharing options...
