message: I've removed the remarks about controlling 100+ missiles. I'd like to see the citation for that, but I doubt that one exists. I also attempted to clarify missile guidance vs fire control. The paragraph probably needs more work, but I haven't the time to look for references right now. --Dual Freq 01:29, 12 April 2006 (UTC)

thread_title: SPY-1

message: (1)  Phased arrays work with any type of wave energy.
(2)  The phased array concept works whether you are sending or receiving signals, i.e. even if you are only listening.
(3)  Search the Internet for "phased array microphone" to read about examples of acoustic receive-only mode.
(4)  Is 3-D seismic analysis of signals from an array of geophones a phased array application?  
(5)  This is a good article on phased array radar.  I'd like to see it expanded to include other wave energy and other applications.  This is WAY out of my field (geology) and I don't feel competent to expand it.

replies: text: (4) Seismic analysis that uses continuous waves from a vibrator as source treats its array of geophones as a phased array. Other seismic explorations use an impulse source such as an explosion and here the geophone signals are combined with different delays to get a similar form of steerability. Note that it is not necessary for all the geophones of an array to be present at once: at sea it is common for a boat to tow a string of microphones whose detections of repeated explosions are recorded for combination later as a virtual or "synthetic" wide-area array.84.210.139.189 19:07, 13 January 2007 (UTC)
thread_title:  Other Types of Energy and Send versus Receive 

message: This article states "We will begin from the N-slit diffraction pattern derived on the diffraction page." But there is no derrivation on that page - only a statement that a rigours matematical derrivation gives the equation shown. —The preceding unsigned comment was added by 213.78.42.15 (talk) 09:06, 26 April 2007 (UTC)
replies: text: Yeah, the "Mathematical perspective and formulae" section needs to be cleaned up. Beyond referring to a non-existent derivation, there is no definition of symbols, and the small angle sine approximation is used with no justification I can see. If someone knows what's going on here, please edit. 130.216.54.198 (talk) 23:56, 30 March 2008 (UTC)

thread_title:  Math error? 

message: I was reading a Nobel lecture here.
Look particularly at pages 239-240 (14-15 in the pdf). I know this was before radar, but doesn't this make it look like Braun in 1905 made the first successful attempt at phased array transmission? Phased array doesn't only refer to radar.

thread_title:  Very Large Array 

message: Phased arrays have been used on aircraft for some time. I think perhaps they warrant a section to explain their history, such as their initial use for ground targetting on aircraft like the B-1 and their later use as high powered, advanced interception radars on aircraft like the Mig-31. It was a significant chapter in the advancement of airborne radar and also a new use for Phased array's which made them much more common so I think its noteable enough to warrant inclusion.
Also, before you object and point out that there is an article on Active arrays, I'll point out that I'm talking about traditional Phased Arrays. Active Arrays are fundamentally different and probably warrant their own article, but the earlier Phased Arrays which were included on the aircraft I just named were exactly the same as their land and naval counterparts, except for in scale.--Senor Freebie (talk) 13:29, 4 February 2010 (UTC)

thread_title:  External links modified 

message: I attempted to add an external link for a FOSS tool I made for explaining/visualizing phased array antennas(https://phasedarray.mlago.dev). I believe it could be useful for people that want to better visualize the interaction of the waves, it provides many of the images on the article in an interactive way(you can visualize the wave peaks like in the first image, or the electric field like in the second image, generate, antenna diagrams, etc). I believe it could be helpful, and assumed it was on topic, since it is very similar to another site link, "Software tool to predict the radiation pattern of an antenna array", although mine is more focused on visualization instead of the produced data. The link was removed, apparently automatically by Huggle. , is this intended? can we whitelist the link, should I perform any improvement, or further clarification on the website for it to be acceptable? I really do believe people might find this useful(at least I searched a long time for it before setting out to do it). ArthurMLago (talk) 00:25, 10 November 2023 (UTC)
replies: text: I agree with the removal. Wikipedia isn't a link directory - it isn't a place to provide links to software you have written, even if they are on topic and helpful that is not sufficient for inclusion. MrOllie (talk) 02:35, 10 November 2023 (UTC)
