Uma kuqhathaniswa nobuchwepheshe be-Optical obufana ne-3D ToF kanye ne-imaging yokubuka, i-millimeter-wave radar inobubanzi obude futhi nokungena okunamandla. Inezinzuzo ezithile maphakathi nebanga elide kanye nokukhonjwa kwezinto ezihambayo, futhi inani lokufakwa ohlelweni olufanayo lincane. Igagasi le-millimeter elithuthukisiwe lingalungele uhlelo olubanzi lwezinhlelo zokusebenza zokubona amaphuzu amaningi.
Amandla okuthuthukiswa kwemakethe aqinile ngokwemvelo adonsela abahlinzeki bezingxenye eziningi ze-auto nabakhiqizi be-chip ukuncintisana emhlabathini ophakeme. Njengomuntu omkhulukazi emkhakheni wama-sensor chip, i-TI igqame kanjani?
Ngokusho kukaMicronet we-TI, TI's ephezulu ukusebenza kwe-RFCMOS MMIC (AWR2243, AWR1243) kanye nezixazululo ze-single-chip (AWR1843, AWR1642) zinikeza inhlanganisela evelele kakhulu yamandla okuphuma nesigaba nokulawula umsindo emakethe, ngenkathi ine-The advanced advanced The module yokusebenza kwedijithali ibona ukumiswa kwe-chirps okusheshayo nokuguquguqukayo nokuqapha okwakhelwe ngaphakathi kwe-FuSa, futhi akudingi ukubamba iqhaza ngokweqile nomthwalo we-chip yokulawula eyinhloko ukuqedela le misebenzi.
Izimo ezengeziwe zohlelo lokusebenza zidinga izinzwa ezingama-millimeter-wave hhayi nje ukuba namandla okuqonda, kodwa futhi nokwenza izinqumo zesikhathi sangempela ohlangothini lwasekhaya ngenkathi kugwenywa ukuphazanyiswa, okuletha izidingo ezintsha nezinselele emakethe yamanje ye-millimeter-wave radar. I-TI ithe i-TI millimeter wave sensors isekela imikhiqizo ye-60Ghz frequency band kanye nemikhiqizo ye band ejwayelekile engu-77Ghz. Njengamanje, imikhiqizo ye band ejwayelekile ye-60Ghz isetshenziswa kakhulu kuma-band frequency band kanye nezicelo zokutholwa kwezangaphakathi, njengokutholwa yilungu nokushayela e-cockpit. Ukutholwa kwesiginali. Ibhendi yemvamisa ye-60Ghz ngaphakathi kohlelo lokutholwa kwamakhabethe ezimoto ngeke iphazamise isiginali radar yezimoto engu-77Ghz.
I-chip ye-radar ye-TI ine-module eyakhelwe ngaphakathi ye-HWA, futhi injini ye-FFT kumamojuli we-HWA2.0 inomsebenzi wangaphambi kokusebenza wokuthola indawo yomthombo wokuphazanyiswa futhi yenze buthaka nomthelela wokuphazamiseka, okwenza ama-radar amabili asebenze ku ibhendi ejwayelekile efanayo ngasikhathi sinye. Ngeke kubangele ukushubela phezulu kwesiginali ndawonye futhi kuthinte ukusebenza.
Ukuvela kusuka ku-ADAS kuya ekushayeleni okuphezulu okuzimele kukhuthaze ukukhula kwemakethe ye-radar millimeter-wave imaging. Kodwa-ke, imboni yamanje isisesigabeni sokuthandwa yi-ADAS. Ngabe yiziphi izinselelo zokufika kwezinga eliphakeme lokushayela elizimele okuletha emakethe yamarimitha egagasi lokulinganisa ngokuzayo?
I-TI ibuye yasho ukuthi ngamazinga aphezulu ezidingo zokushayela ezizimele, irar imaging ephezulu ye-imaging idinga amandla womtholi wamabhokisi asebangeni elide kanye nesixazululo esikhulu se-angle. Isibonelo, uhlelo lidinga ukukwazi ukuhlukanisa amamitha angama-250 kude nezimoto ezimbili ezihamba ohlangothini olufanayo nangejubane elifanayo kwimizila eseceleni, edinga uhlelo ukuba namandla okuthola okuqondiwe okungaphansi kwesilinganiso esingu-1 sokuxazululwa kwe-angular; kwesinye isibonelo, isistimu idinga ukukwazi ukubona ukupaka ngaphansi kwebhuloho amamitha ayi-200 kude noma imoto emhubheni, okudinga ukuthi uhlelo lube nesisombululo se-angular esingaphansi kweleveli eli-1 endaweni ebheke phezulu. Lezi zinselelo zidinga i-radical imaging imaging ephezulu.
Uma ngibheka phambili, i-TI ikholelwa ukuthi i-radar kanye ne-lidar ephezulu yokuqagela kuzohlangana emakethe futhi zihambisane. Kumakethe yokushayela yokuzimela esezingeni eliphansi (Izinga le-0-3) ngezidingo eziphansi zamanani aphansi, ukusetshenziswa kwe-millimeter-wave radar nezinhlelo zekhamera kuzovama kakhulu, ngoba izindleko zokusebenzisa uhlelo ziphakeme.
