Imininingwane yezingozi ikhombisa ukuthi izingozi ezingaphezu kuka-76% zidalwa amaphutha abantu kuphela;futhi ku-94% wezingozi, amaphutha omuntu afakiwe.I-ADAS (Advanced Driver Assistance Systems) ifakwe izinzwa eziningana ze-radar, ezingasekela kahle yonke imisebenzi yokushayela okungenamuntu.Yiqiniso, kuyadingeka ukuchaza lapha, i-RADAR ibizwa ngokuthi i-Radio Detection And Ranging, esebenzisa amaza omsakazo ukuthola nokuthola izinto.
Amasistimu amanje e-radar ngokuvamile asebenzisa amaza okusebenza angu-24 GHz noma angu-77 GHz.Inzuzo ye-77GHz ilele ekunembeni kwayo okuphezulu kokukalwa kwebanga nesivinini, ukulungiswa okungcono kwe-engeli evundlile, nevolumu ye-antenna encane, futhi kukhona ukuphazamiseka kwesignali okuncane.
Ama-radar ebanga elifushane ngokuvamile asetshenziselwa ukufaka izinzwa ze-ultrasonic futhi asekele amazinga aphezulu okushayela okuzenzakalelayo.Kulokhu, izinzwa zizofakwa kuwo wonke amakhona emoto, futhi inzwa ebheke phambili yokuthola ibanga elide izofakwa ngaphambili emotweni.Kusistimu ye-radar enekhava egcwele engu-360° yomzimba wemoto, izinzwa ezengeziwe zizofakwa phakathi nezinhlangothi zombili zomzimba wemoto.
Ngokufanelekile, lezi zinzwa ze-radar zizosebenzisa ibhendi yefrikhwensi engu-79GHz kanye nomkhawulokudonsa wokudlulisa ongu-4Ghz.Kodwa-ke, indinganiso yokudlulisa isignali yomhlaba wonke okwamanje ivumela kuphela umkhawulokudonsa ongu-1GHz esiteshini esingu-77GHz.Namuhla, incazelo eyisisekelo ye-radar MMIC (i-monolithic microwave integrated circuit) ithi "3 amashaneli okudlulisa (TX) kanye namashaneli atholayo angu-4 (RX) ahlanganiswe kusekethe eyodwa".
Isistimu yokusiza abashayeli engaqinisekisa i-L3 nangaphezulu kwemisebenzi yokushayela engenamuntu idinga okungenani amasistimu wezinzwa ezintathu: ikhamera, i-radar nokutholwa kwe-laser.Kufanele kube nezinzwa eziningana zohlobo ngalunye, zisakazwe ezindaweni ezihlukene zemoto, futhi zisebenze ndawonye.Nakuba ubuchwepheshe be-semiconductor obudingekayo kanye nobuchwepheshe bokuthuthukiswa kwezinzwa zekhamera kanye ne-radar manje buyatholakala, ukuthuthukiswa kwezinhlelo ze-lidar kuseyinselelo enkulu futhi engazinzile kakhulu mayelana nezindaba zobuchwepheshe nezohwebo.
