Pilotasso Posted April 24, 2009 Posted April 24, 2009 (edited) Check this out. APG-81 early version some years ago. Cusrious how it apears tu use multiple beams to scan areas of interest instead of just sweeping sidways. Fast like a bat out from hell too. Edited April 24, 2009 by Pilotasso .
Mugatu Posted April 24, 2009 Posted April 24, 2009 just a single beam, just showing how quickly it's tasked.
nscode Posted April 24, 2009 Posted April 24, 2009 For the last time, AESA CAN split its beam into multiple independent beams. It is NOT just single beam giving apperance of multiple beams by moving quickly (although that can be done too). Never forget that World War III was not Cold for most of us.
Boneski Posted April 24, 2009 Posted April 24, 2009 For the last time, AESA CAN split its beam into multiple independent beams. Geezzz Why So Serious??? Is it really that important??? Take some Meds for that ok??? Dual beam single beam... it will be ok.... Okay?? 2 My mission is to fly, fight, and win. o-:|:-o What I do is sometimes get a tin of soup, heat it up, poach an egg in it, serve that with a pork pie sausage roll.
Weta43 Posted April 24, 2009 Posted April 24, 2009 Because of history... Damn - you had my hopes up - I thought it was going to be actual 'footage' of the radar in action & I'm not convinced it isn't just a manufacturer's promotional simulation... 22 seconds into the video the first two targets are identified & immediately have an apparently accurate speed / direction vector marker attached to them - at 0.1 seconds into the test. At 800 km/h the target has only moved 22m in 0.1 sec. Even if all the 22m were 'lateral' 22m movement at > 80nm (from the scale in video) is going to be below both the angular and range resolution of the beam at that range. You'd get a closing speed off the doppler shift, but the vector on the farthest target is not so far off head on, so ther is no way that the lateral compnent of the 22m is going to give enough information for an accurate vector - yet it does .... Cheers.

Mugatu Posted April 26, 2009 Posted April 26, 2009 (edited) Sorry nscode, it's a single end of story. Read the NG white papers and you'll see a single beam is used for surv and tracking while sub apps may be used for ECM, data xfer etc.... Edited April 26, 2009 by Mugatu

Toooooo right.... About the 'picture' given by the scope, it must be some busy airspace somewhere in the US, and according to that, they must be quite large aircraft. The point is wether it does help the radar to acquire precice info on it, or not. The other interesting thing is that the last two targets were vectored after those 'many' seconds, which in, even the farthest targets were acquired accurately. I think that technology is above the knowledge of many of us :D [sIGPIC]http://www.forum.lockon.ru/signaturepics/sigpic5279_1.gif[/sIGPIC] I could shot down a Kitchen :smartass:
