The article lacks any mention of applications in search and rescue. I added a section header but it was reverted by Pierre cb who presumably does not consider the subtopic relevant, but did not say why, so I open this for discussion, as I think it is relevant, and could be useful to the reader. Radar has important applications in maritime search and rescue, so there should be at minimum some mention and a link to an article covering it in more detail, and preferably a summary section or paragraph, but I do not have any verifiable information to add myself.

I also could not find any mention of target acquisition or radar guided weapons, which seems a bit odd as those are significant applications too. Cheers, · · · Peter Southwood ^(talk): 08:20, 26 March 2024 (UTC)Reply

I did say why (Remove empty useless section). It is not because I don't think it is relevant to talk about those subjects but you cannot put an empty section in an article. You must to at least put a paragraph describing what you are talking about. On the other hand, what you just wrote above does not need a separate section, just adding a paragraph in the section Radar#Applications is well enough.

In the Wikipedia article on 'laser', it is explicitly mentioned that 'laser' is an anacronym. 'radar' is also an anacronym, and this phenomenon is spelled out, but the term 'anacronym' is not explicitly cited, but it ought to be. Kontribuanto (talk) 19:11, 22 April 2024 (UTC)Reply

This is mention in the 3rd paragraph of the introduction: "The term RADAR was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging".The term radar has since entered English and other languages as a common noun, losing all capitalization." But I have added the term to the sentence. Pierre cb (talk) 23:05, 22 April 2024 (UTC)Reply

Further explanation on how resolution is improved by increasing signal frequency seems in order. It is unclear whether range, or angle, resolution is being claimed as improved through frequency increase. 2604:CA00:14B:4684:0:0:1063:5D72 (talk) 05:28, 7 January 2025 (UTC)Reply

"Also, in late 1941 Popular Mechanics had an article in which a U.S. scientist speculated about the British early warning system on the English east coast and came close to what it was and how it worked"

The citation for this line doesn't seem to contain the mentioned article. ~2026-37619-8 (talk) 02:33, 18 January 2026 (UTC)Reply
