Ukuvela kwe-Passive Electronically Scanned Array (PESA) kuya ku-Active Electronically Scanned Array (AESA) kumelela intuthuko ebaluleke kakhulu kubuchwepheshe besimanje be-radar. Ngenkathi zombili izinhlelo zisebenzisa isiqondiso se-electronic beam, izakhiwo zazo eziyisisekelo zihluka kakhulu, okuholela kumehluko omkhulu wokusebenza.
Kuzinhlelo ze-PESA, iyunithi yesidluliseli/isamukeli esisodwa iphakela inethiwekhi yeziguquli zesigaba ezilawula iphethini yemisebe yezinto ze-antenna ezingenzi lutho. Lo mklamo ubeka imikhawulo ekuphikisweni kwe-jamming kanye nokusebenza kwe-beam. Ngokuphambene, irada ye-AESA ihlanganisa amakhulu noma izinkulungwane zamamojula angawodwana okuthumela/okwamukela, ngalinye linesigaba salo nokulawula i-amplitude. Lesi sakhiwo esisabalalisiwe sinika amandla okuguquguquka okuhlanganisa ukulandelela okuqondiwe okuningi ngasikhathi sinye, ukwakheka kwe-beamform okuguquguqukayo, kanye nezinyathelo zokuphikisa ezithuthukisiwe ze-elekthronikhi.
Izakhi ze-antenna ngokwazo ziye zavela eceleni kwalezi zinhlelo.Ama-antenna ahleliwe, ngemiklamo yazo esezingeni eliphansi, ekhiqizwa ngobuningi, isiphenduke inketho ekhethwayo yezinhlelo ze-AESA ezidinga ukufakwa okuhlangene, okuvumelanayo. Ngaleso sikhathi, izimpondo ze-ODM zophondo oluyindilinga ziyaqhubeka nokusebenza izindima ezibalulekile ezinhlelweni ezikhethekile lapho amaphethini azo alinganayo futhi abanzi.
Izinhlelo zesimanje ze-AESA zivame ukuhlanganisa kokubili ubuchwepheshe, ukuhlanganisa izinhlelo ezifanayo zemisebenzi eyinhloko yokuskena ngokuphakelayo kophondo oluyindilinga ukuze kufakwe okukhethekile. Le ndlela eyingxubevange ikhombisa ukuthi idizayini ye-antenna ye-microwave isiye yaba yinkimbinkimbi kangakanani ukuze ihlangabezane nezidingo ezahlukahlukene zokusebenza kuzo zonke izinhlelo zokusebenza zezempi, zezindiza, nezesimo sezulu.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
