Airborne early warning and control (AEW&C) aircraft \u2013 long considered indispensable yet vulnerable command nodes \u2013 have historically been high-value targets. Their powerful radar emissions, while essential for managing the battlespace, make them visible from hundreds of kilometres away.<\/p>\n
But the Chinese scientists said they found a way to make AEW&C signals exceptionally resistant to interception and geolocation.<\/p>\n
This method assigns each antenna a minutely varied frequency, akin to a hundred singers harmonising the same melody yet each subtly diverging in pitch. This renders the signal chaotic at a distance, obscuring directional origin.<\/p>\n
To an adversary trying to track the platform by listening to its radio emissions, the signal could behave like the phantom of the opera \u2013 fluctuating, scattering and morphing beyond recognition.<\/p>\n
At the heart of this innovation lies a new class of radar system known as frequency diverse array (FDA) technology, which engineers describe as a \u201cparadigm shift\u201d from traditional phased array radars.<\/p>\n","protected":false},"excerpt":{"rendered":"Airborne early warning and control (AEW&C) aircraft \u2013 long considered indispensable yet vulnerable command nodes \u2013 have historically…\n","protected":false},"author":2,"featured_media":23605,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[74],"tags":[19959,19960,19963,19958,1793,19956,18,19961,19962,2898,19964,19,17,19957,19954,82,19955],"class_list":{"0":"post-23604","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-technology","8":"tag-aero-weaponry","9":"tag-aewc","10":"tag-air-force-engineering-university","11":"tag-airborne-early-warning","12":"tag-beijing","13":"tag-chinese-air-force","14":"tag-eire","15":"tag-electronic-intelligence-systems","16":"tag-electronic-warfare","17":"tag-fda","18":"tag-frequency-diverse-array","19":"tag-ie","20":"tag-ireland","21":"tag-pla","22":"tag-space-time-frequency-cooperative-anti-passive-detection","23":"tag-technology","24":"tag-wang-bo"},"share_on_mastodon":{"url":"","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/23604","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=23604"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/23604\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/23605"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=23604"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=23604"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=23604"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
