Kushanduka kubva paPassive Electronically Scanned Array (PESA) kuenda kuActive Electronically Scanned Array (AESA) kunomiririra kufambira mberi kukuru mune tekinoroji yeradar yemazuva ano. Kunyange zvazvo masisitimu ese ari maviri achishandisa electronic beam steering, magadzirirwo awo akasiyana zvikuru, zvichikonzera kusiyana kukuru kwekushanda.
MuPESA systems, imwe chete transmitter/receiver unit inopa network ye phase shifters inodzora radiation pattern ye passive antenna elements. Iyi dhizaini inoderedza kusagadzikana kwejamming uye beam agility. Kusiyana neizvi, AESA radar inosanganisira mazana kana zviuru zve transmitter/receiver modules, imwe neimwe iine phase yayo uye amplitude control. Iyi distributed architecture inobvumira kugona kuchinja kunosanganisira multi-target tracking panguva imwe chete, adaptive beamforming, uye electronic counter-countermeasures dzakasimba.
Zvinhu zveantenna pachazvo zvakashanduka pamwe chete nemasisitimu aya.Ma antenna eplanar, nemagadzirirwo awo asina kunyanya kuoneka, anogona kugadzirwa zvakanyanya, ave sarudzo inofarirwa kune masisitimu eAESA anoda kuiswa kwakabatana uye kwakabatana. Zvichakadaro, maantenna eODM conical horn anoramba achiita mabasa akakosha mumabasa akasiyana-siyana ane mapatani akaenzana uye akafara.
Masisitimu emazuva ano eAESA anowanzo sanganisa matekinoroji ese ari maviri, achibatanidza ma "planar arrays" emabasa makuru ekuskena ne "conical horn feeds" kuti afukidzwe nehunyanzvi. Maitiro aya anoratidza kuti dhizaini ye "microwave antenna" yave iri nani sei kuti isangane nezvinodiwa zvakasiyana-siyana zvekushanda mumauto, ndege, uye mamiriro ekunze.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
