Ukuvela ku-Passive Electronically Scanned Array (PESA) kuya ku-Active Electronically Scanned Array (AESA) kumelela intuthuko ebaluleke kakhulu kubuchwepheshe besimanje be-radar. Nakuba zombili izinhlelo zisebenzisa isiteringi se-electronic beam, izakhiwo zazo eziyisisekelo ziyahlukahluka kakhulu, okuholela ekwehlukeni okukhulu kokusebenza.
Ezinhlelweni ze-PESA, iyunithi eyodwa yokudlulisela/yokwamukela iphakela inethiwekhi yama-phase shifters alawula iphethini yemisebe yezinto ze-antenna ezingasebenzi. Lo mklamo ubeka imikhawulo ekumelaneni nokujima kanye nokuguquguquka kwemisebe. Ngokuphambene nalokho, i-radar ye-AESA ifaka amakhulu noma izinkulungwane zamamojula okudlulisa/okwamukela ngamanye, ngalinye linokulawula kwalo kwesigaba kanye ne-amplitude. Lo mklamo osatshalaliswayo uvumela amakhono okuguqula okuhlanganisa ukulandelela okuqondiwe okuningi ngasikhathi sinye, ukwakheka kwemisebe okuguquguqukayo, kanye nezinyathelo zokuphikisana ze-elekthronikhi ezithuthukisiwe kakhulu.
Izakhi ze-antenna ngokwazo zivele kanye nalezi zinhlelo.Ama-antenna e-Planar, ngemiklamo yazo ephansi, ekhiqizwa ngobuningi, isibe ukukhetha okuthandwayo kwezinhlelo ze-AESA ezidinga ukufakwa okufushane, okunesimo esifanayo. Okwamanje, ama-antenna e-ODM aqinile ayaqhubeka nokusebenza izindima ezibalulekile ezinhlelweni ezikhethekile lapho amaphethini awo alinganayo kanye nobubanzi
Izinhlelo zesimanje ze-AESA zivame ukuhlanganisa zombili ubuchwepheshe, zihlanganise ama-planar arrays emisebenzi yokuskena eyinhloko kanye nokuphakelwa kwezimpondo eziqondile ukuze kuhlanganiswe okukhethekile. Le ndlela ehlanganisiwe ibonisa ukuthi ukwakheka kwe-antenna ye-microwave kuye kwaba yinkimbinkimbi kangakanani ukuze kuhlangatshezwane nezidingo zokusebenza ezahlukahlukene kuzo zonke izinhlelo zokusebenza zempi, zezindiza kanye nezesimo sezulu.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
