Kusintha kuchokera ku Passive Electronically Scanned Array (PESA) kupita ku Active Electronically Scanned Array (AESA) kukuyimira kupita patsogolo kwakukulu muukadaulo wamakono wa radar. Ngakhale kuti makina onsewa amagwiritsa ntchito chiwongolero chamagetsi, mapangidwe awo oyambira amasiyana kwambiri, zomwe zimapangitsa kuti magwiridwe antchito asiyane kwambiri.
Mu makina a PESA, chipangizo chimodzi chotumizira/cholandirira chimadyetsa netiweki ya ma phase shifters omwe amawongolera mawonekedwe a radiation a zinthu zopanda mphamvu za antenna. Kapangidwe kameneka kamapereka zoletsa pakukana kwa jamming ndi mphamvu ya beam. Mosiyana ndi zimenezi, radar ya AESA imaphatikizapo mazana kapena zikwi za ma transmit/receiver modules, iliyonse ili ndi gawo lake ndi ulamuliro wake wa amplitude. Kapangidwe kameneka kamalola mphamvu zosinthira zinthu kuphatikizapo kutsatira zinthu zambiri nthawi imodzi, kusintha kwa beamforming, komanso kukonza kwambiri njira zamagetsi zotsutsana ndi zinthu zina.
Zinthu za antenna zokha zasintha mogwirizana ndi machitidwe awa.Ma antenna a pulaneti, ndi mapangidwe awo otsika komanso opangidwa mochuluka, akhala chisankho chabwino kwambiri pamakina a AESA omwe amafuna kukhazikitsidwa pang'ono komanso kofanana. Pakadali pano, ma antenna a nyanga ya ODM conical akupitilizabe kugwira ntchito zofunika kwambiri m'mapulogalamu apadera pomwe mapangidwe awo ofanana komanso otakata.
Machitidwe amakono a AESA nthawi zambiri amaphatikiza ukadaulo wonsewu, kuphatikiza ma planar arrays a ntchito zazikulu zowunikira ndi ma feed a nyanga yozungulira kuti aphimbe zinthu zapadera. Njira yosakanikirana iyi ikuwonetsa momwe kapangidwe ka ma antenna a microwave kakhalira kosangalatsa kwambiri kuti kakwaniritse zofunikira zosiyanasiyana pantchito zankhondo, ndege, komanso nyengo.
Kuti mudziwe zambiri zokhudza ma antenna, chonde pitani ku:
