Eminyakeni eyishumi edlule, i-radar yamagagasi angamamilimitha (mmWave) ishintshe kusukela ekubeni yinzwa eyingqayizivele ezimotweni ezimbalwa ezisezingeni eliphezulu kuya ekubeni yingqalasizinda ebalulekile yokuqonda ezimotweni ezihlakaniphile. Kusukela ekulawuleni ukuhamba ngesikebhe okuguquguqukayo (i-ACC) kanye nokubhuleka okuphuthumayo okuzenzakalelayo (i-AEB) kuya ekuzulazuleni okushesha kakhulu kwesivinini esiphezulu ku-autopilot (NOA) kanye nosizo lokushayela emadolobheni, i-radar yamaWave idlala indima ebalulekile ekuboneni indawo yezimoto.
Njengoba isidingo sezinhlelo zokusiza abashayeli ezithuthukisiwe sikhula, izinhlelo ze-radar ngokwazo ziyathuthuka ngokuqhubekayo. Ama-radar okuqala anobukhulu obubili athathelwe indawo kancane kancane ama-radar okuthwebula izithombe e-4D akwazi ukuhlinzeka ngolwazi lwebanga, ijubane, i-azimuth, kanye nokuphakama ngasikhathi sinye, ebeka izidingo eziqinile ebangeni lokuthola, isixazululo se-angular, kanye namakhono okuhlonza okuqondiwe. Ngaphandle kokuthuthukiswa kwamandla okucubungula ama-chip kanye nobuchwepheshe be-algorithm, ukwakheka kohlelo lwe-antenna kuvele njengento ebalulekile evumela lokhu kuthuthukiswa kokusebenza. Isibonelo, i-radar yokuthwebula izithombe enesinqumo esiphezulu ye-Continental i-ARS540 ifinyelela ibanga lokuthola elicishe libe amamitha angu-300 ngokusebenzisa ama-antenna aqinile, ngasikhathi sinye ilandelela amakhulu ezinhloso. Ngaphakathi, imikhiqizo ye-radar yesizukulwane esilandelayo ye-4D mmWave isebenzisa ama-antenna amakhulu kanye nezakhiwo ze-waveguide ezilungiselelwe ukuthuthukisa ukuqashelwa okuqondiwe okude, okuvumela ukutholakala kwangaphambili kwezimoto, izivikelo zokuvikela, kanye nezithiyo ezimile. Ngemuva kwalokhu kuthuthuka, kuvele umkhuba ocacile: ama-radar e-mmWave asebenza kahle kakhulu asebenzisa kakhulu ukwakheka kwe-antenna ye-waveguide.
Kuzinhlelo ze-radar ze-mmWave, i-antenna inesibopho sokukhipha kanye nokwamukela amagagasi kagesi, okuthonya ngqo ububanzi bokuthola, ukulungiswa kwe-angular, kanye nokuthembeka kwesignali. Imiklamo ye-radar ye-mmWave yokuqala yayisebenzisa kakhulu ama-antenna e-PCB microstrip ngenxa yobulula bawo, izindleko eziphansi, kanye nokulula kokukhiqizwa okukhulu. Kodwa-ke, njengoba amaza e-radar enyuka afinyelela ku-77 GHz nangaphezulu, imikhawulo yama-antenna e-PCB iyacaca. Izakhiwo ze-dielectric zezinto ze-PCB ziletha ukulahlekelwa kokusabalala kumaza e-mmWave, kunciphisa amandla esignali, kuyilapho imikhawulo ekusebenzeni kahle kwemisebe kanye nekhono lokwakha imisebe inciphisa ukusebenza kwesistimu.
Ama-antenna e-Waveguide, ngokuphambene, aqondisa amaza kagesi ngokusebenzisa izakhiwo zensimbi, anciphisa kakhulu ukulahlekelwa kokusabalala futhi afinyelele ukusebenza kahle kwemisebe ephezulu. Ngenxa yalokho, ezinhlelweni ezifuna ububanzi obubanzi bokutholwa kanye nesisombululo esihle se-angular, ama-antenna e-waveguide avele njengesixazululo esithandwayo. Kodwa-ke ukwamukelwa kabanzi kwama-waveguide kuletha izinselele ezintsha zokukhiqiza.
Ngokungafani nama-antenna e-PCB, ama-antenna e-waveguide ayizakhiwo ze-electromagnetic zensimbi eziqondile. Ukusabalala kwamagagasi ngaphakathi kwe-waveguide kuzwela kakhulu ekunembileni kobukhulu be-cavity kanye nokuqhuba kwangaphakathi. Ukuphambuka kobukhulu be-waveguide noma ubulukhuni bomphezulu kungalimaza inzuzo, kuphambukise isiqondiso se-beam, futhi kwandise ukulahleka kwesignali, ekugcineni kuthinte ibanga lokutholwa kwe-radar kanye nokuqashelwa kwethagethi. Ukwenziwa kwendabuko kuncike ekusetshenzisweni kwe-CNC noma ekugayweni kwensimbi, okuqinisekisa ukusebenza okunembile kwe-electromagnetic kodwa kubhekene nemikhawulo ebalulekile ezindleko kanye nokukhula. Izakhiwo zamagagasi e-millimeter, ngokuvamile ezingamamilimitha ambalwa ngobukhulu kanye nokubekezelela amashumi ama-micron, zidinga imishini eyinkimbinkimbi kanye nokulawulwa kwenqubo encane. Ukwenziwa kwemishini kufaneleka ukukhiqizwa kwezinga elincane kodwa kuba yinto evimbelayo kuma-radar ezimoto emakethe enkulu noma izinzwa zabathengi.
Ukuze kuhlanganiswe ukusebenza okuphezulu kwe-electromagnetic kanye nokukwazi ukukhiqiza, imboni ihlole ama-antenna e-waveguide ensimbi. Umqondo oyisisekelo ukuhlukanisa ukwakheka kwesakhiwo kusuka ekuqhubeni kukagesi. Esikhundleni sokulungisa ibhlogo lensimbi lonke, le ndlela isebenzisa "ukwakheka kwesakhiwo + ukwenziwa kwensimbi ebusweni."
Ekuqaleni, umgodi we-waveguide wakhiwa kusetshenziswa ukubumba ngomjovo, ukubumba ngokucindezela, noma ukukhiqizwa okungeziwe ngepulasitiki yobunjiniyela noma ama-polymer asebenza kahle, okunikeza ukuguquguquka nokufaneleka kokukhiqizwa komthamo ophezulu. Ngemva kokwenziwa kwesakhiwo, ukwelashwa kwangaphambili kwendawo—ukuhlanza, ukugoqa, noma ukusebenza kwamakhemikhali—kusetshenziswa ukuthuthukisa ukunamathela kwensimbi. Ukufakwa okulandelayo kwengqimba yokuqhuba okuqhubekayo, nge-PVD, i-electroplating, noma i-electroless plating, ngokuvamile ngethusi, i-nickel, noma isiliva, kuguqula isakhiwo sibe yi-waveguide yokuqhuba ephansi. Izindawo ezibalulekile ezifana nokuvuleka kwemisebe noma izifunda ze-interface zingase zithole i-metallization yendawo noma i-fine machining ukuze kuthuthukiswe ukusebenza kwe-electromagnetic.
Le ndlela "yokwakheka + insimbi" igcina ukusebenza okuphezulu kwama-waveguides endabuko ngenkathi ivumela ukukhiqizwa okuguquguqukayo nokusebenzayo. Izingxenye ezibunjwe ngomjovo zivumela ukwenziwa okusheshayo kobuningi, kunciphisa izindleko; ama-substrate epulasitiki anciphisa isisindo, asekela ukukhanya kwezimoto, kanye nokuphrinta kwe-3D kusiza ngejiyomethri eyinkimbinkimbi, kuthuthukisa ukwakheka kwama-antenna amakhulu. Le ndlela ilinganisela ngempumelelo ukusebenza kahle kwe-electromagnetic, ukukhiqizwa, kanye nokulawulwa kwezindleko, okwenza ama-antenna e-waveguides ensimbi avame kakhulu emikhiqizweni ye-radar ye-mmWave.
I-Zhihua Vacuum inikeza izixazululo eziphelele zokukhiqiza ngobuhlakani ama-antenna e-radar radar e-mmWave aqondiswe ngensimbi. Umugqa wabo wokukhiqiza i-coating eqhubekayo evundlile, osekelwe ekuqhumeni kwe-vacuum, ufeza ukufakwa kwensimbi okunezingqimba ezimbili noma eziningi kumjikelezo owodwa we-vacuum ngokulawula okunembile nokuvumelana. Uma kuqhathaniswa nokuphrinta kwe-electrode yesiliva yendabuko, ama-electrode ethusi afakwe i-magnetron athuthukisa ukuhanjiswa, ukuthembeka, kanye nokusebenza okulwa ne-sulfuration ngenkathi ehlisa izindleko. Ukuphathwa okuzenzakalelayo kanye nokuhambisana nosayizi abahlukahlukene be-ceramic kuqinisekisa ukuphuma okuphezulu kokukhiqizwa kwe-mass. Njengoba sekuyiminyaka engaphezu kwengu-30 kubuchwepheshe be-vacuum coating, kufaka phakathi i-PVD, i-PECVD, kanye ne-ALD, i-Zhihua Vacuum inikeza ukuhlanganiswa kwenqubo okwenziwe ngokwezifiso, okuyimfihlo okuvela ku-R&D ngokukhiqiza kwe-mass.
Njengoba ubuchwepheshe bokushayela obuzimele kanye nokuzwa okuhlakaniphile buthuthuka, izidingo zokusebenza kwe-radar ye-mmWave ziyaqhubeka nokukhula. Ukuvela kuma-antenna e-PCB microstrip kuya kuma-antenna e-waveguide, futhi manje kuya ezakhiweni ze-waveguide zensimbi, kubonisa indima ebalulekile yobuchwepheshe bokukhiqiza ama-antenna. Ngokuhlukanisa ukwakheka kwesakhiwo nokusebenza okuqhubayo, ama-antenna e-waveguide ensimbi afinyelela kokubili ukusebenza okuphezulu kwe-electromagnetic kanye nokusebenza kahle kokukhiqiza, okunikeza ukuguquguquka kwemiklamo ye-radar eyinkimbinkimbi. Njengoba isayensi yezinto ezibonakalayo kanye namasu okukhiqiza ethuthuka, le ndlela ilungele ukudlala indima ebaluleke kakhulu ezinhlelweni ze-radar ze-mmWave zesikhathi esizayo.
