In real combat scenarios, military commanders place greater trust in radar satellites, which can function reliably around the clock and under all weather.<\/p>\n<p datatype=\"p\" data-qa=\"Component-Component\" class=\"e8zc9q40 css-1c6uqr6 ec74h0k1\">For decades, detecting stealth aircraft like the F-22 Raptor or B-21 Raider using a space-borne radar was widely considered unfeasible. If such detection was possible from orbit, these iconic stealth programmes might never have been approved.<\/p>\n<p datatype=\"p\" data-qa=\"Component-Component\" class=\"e8zc9q40 css-1c6uqr6 ec74h0k1\">While a stealth aircraft\u2019s radar cross-section (RCS) appears significantly larger when viewed from above in low Earth orbit \u2013 some estimates suggest it could be as big as a barn door \u2013 this advantage is offset by an overwhelming challenge: background clutter.<\/p>\n<p datatype=\"p\" data-qa=\"Component-Component\" class=\"e8zc9q40 css-1c6uqr6 ec74h0k1\">The chaotic reflection of radar signals from rough sea surfaces or mountainous terrain generates intense noise that can easily drown out the faint signature of a moving aircraft.<\/p>\n","protected":false},"excerpt":{"rendered":"For instance, the Jilin-1 commercial satellite constellation successfully tracked an F-22 fighter jet manoeuvring through clouds \u2013 a&hellip;\n","protected":false},"author":2,"featured_media":127748,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[270],"tags":[77146,77150,381,18,77147,77148,19,17,77151,77143,77149,21887,77142,21483,133,77144,74986,451,77145,61469],"class_list":{"0":"post-127747","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-b-21-raider","9":"tag-chen-junli","10":"tag-china","11":"tag-eire","12":"tag-f-22","13":"tag-f-35","14":"tag-ie","15":"tag-ireland","16":"tag-jilin-1","17":"tag-journal-of-radars","18":"tag-l-band","19":"tag-low-earth-orbit","20":"tag-lt-1","21":"tag-northwestern-polytechnical-university","22":"tag-science","23":"tag-shanghai-academy-of-spaceflight-technology","24":"tag-shanghai-jiao-tong-university","25":"tag-space","26":"tag-stealth-aircraft","27":"tag-us-military"},"share_on_mastodon":{"url":"","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/127747","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=127747"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/127747\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/127748"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=127747"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=127747"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=127747"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
