Radar

Lintlha tsa likotsi li bontša hore ho feta 76% ea likotsi li bakoa ke liphoso tsa batho feela;'me ho 94% ea likotsi, liphoso tsa batho li kenyelelitsoe.ADAS (Advanced Driver Assistance Systems) e na le lisensara tse 'maloa tsa radar, tse ka tšehetsang hantle mesebetsi eohle ea ho khanna ntle le motho.Ehlile, hoa hlokahala ho hlalosa mona, RADAR e bitsoa Radio Detection And Ranging, e sebelisang maqhubu a seea-le-moea ho fumana le ho fumana lintho.

Lisebelisoa tsa morao-rao tsa radar hangata li sebelisa 24 GHz kapa 77 GHz maqhubu a sebetsang.Monyetla oa 77GHz o holim'a ho nepahala ha eona ho holimo le ho lekanya lebelo, qeto e betere ea angle e otlolohileng, le molumo o monyane oa antenna, mme ho na le tšitiso e nyane ea lets'oao.

Li-radar tsa nako e khuts'oane hangata li sebelisoa ho nkela li-sensor tsa ultrasonic sebaka le ho ts'ehetsa maemo a holimo a ho khanna a ikemetseng.Ho finyella sena, li-sensor li tla kenngoa k'honeng e 'ngoe le e' ngoe ea koloi, 'me mochine o shebileng pele bakeng sa ho lemoha nako e telele o tla kenngoa ka pele ho koloi.Ka har'a sistimi ea radar e felletseng ea 360 ° ea 'mele oa koloi, li-sensor tse ling li tla kenngoa bohareng ba mahlakore ka bobeli a 'mele oa koloi.

Ka nepo, lisensara tsena tsa radar li tla sebelisa 79GHz frequency band le 4Ghz transmission bandwidth.Leha ho le joalo, maemo a phetisetso ea maqhubu a lets'oao la lefats'e hajoale a lumella feela bandwidth ea 1GHz mocheng oa 77GHz.Matsatsing ana, tlhaloso ea motheo ea radar MMIC (monolithic microwave integrated circuit) ke "3 transmitting channels (TX) le 4 receive channels (RX) li kopantsoe ka potoloho e le 'ngoe".
