Zambiri zangozi zikuwonetsa kuti ngozi zopitilira 76% zimachitika chifukwa cha zolakwika zamunthu;ndipo mu 94% ya ngozi, zolakwika zaumunthu zikuphatikizidwa.ADAS (Advanced Driver Assistance Systems) ili ndi masensa angapo a radar, omwe amatha kuthandizira ntchito zonse zoyendetsa popanda munthu.Inde, ndikofunikira kufotokoza apa, RADAR imatchedwa Radio Detection And Ranging, yomwe imagwiritsa ntchito mafunde a wailesi kuti izindikire ndikupeza zinthu.
Makina a radar apano nthawi zambiri amagwiritsa ntchito ma frequency a 24 GHz kapena 77 GHz.Ubwino wa 77GHz uli pakulondola kwake kwanthawi yayitali komanso kuyeza liwiro, kusanja bwino kopingasa kopingasa, komanso kuchuluka kwa tinyanga tating'onoting'ono, ndipo palibe kusokoneza kwa ma sign.
Ma radar afupikitsa nthawi zambiri amagwiritsidwa ntchito m'malo mwa masensa akupanga ndikuthandizira milingo yayikulu yoyendetsa pawokha.Kuti izi zitheke, masensa adzayikidwa pakona iliyonse ya galimotoyo, ndipo kutsogolo kwa galimotoyo kudzayika sensor yoyang'ana kutsogolo kwa nthawi yayitali.Mu 360 ° yodzaza ndi radar system yamagalimoto, masensa owonjezera adzayikidwa pakati pa mbali zonse za galimoto.
Moyenera, masensa a radar awa adzagwiritsa ntchito 79GHz frequency band ndi 4Ghz transmission bandwidth.Komabe, mulingo wapadziko lonse lapansi wotumizira ma siginecha pano umangolola 1GHz bandwidth mu njira ya 77GHz.Masiku ano, tanthauzo lofunikira la radar MMIC (monolithic microwave integrated circuit) ndi "njira zotumizira 3 (TX) ndi 4 zolandila (RX) zimaphatikizidwa pagawo limodzi".
Dongosolo lothandizira dalaivala lomwe lingathe kutsimikizira L3 komanso pamwamba pa ntchito zoyendetsa mosayendetsedwa ndi anthu zimafunikira ma sensor atatu: kamera, radar ndi laser kuzindikira.Payenera kukhala masensa angapo amtundu uliwonse, ogawidwa m'malo osiyanasiyana agalimoto, ndikugwirira ntchito limodzi.Ngakhale teknoloji yofunikira ya semiconductor ndi teknoloji ya chitukuko cha kamera ndi radar sensor ilipo tsopano, chitukuko cha machitidwe a lidar akadali vuto lalikulu kwambiri komanso losakhazikika pazochitika zamakono ndi zamalonda.
