Xogta shilku waxay muujinaysaa in in ka badan 76% shilalka ay sababaan khaladka bini'aadamka;iyo 94% shilalka, khaladka bini'aadamka ayaa lagu daray.ADAS (Nidaamka Caawinta Darawalka Sare) waxay ku qalabaysan tahay dhowr dareemayaal radar, kuwaas oo si fiican u taageeri kara guud ahaan hawlaha wadista aan cidi wadin.Dabcan, waa lagama maarmaan in halkan lagu sharaxo, RADAR waxa loo yaqaan Raadiyaha Detection And Ranging, kaas oo isticmaala mowjadaha raadiyaha si loo ogaado oo loo helo walxaha.
Nidaamyada radar-ka ee hadda jira guud ahaan waxay adeegsadaan 24 GHz ama 77 GHz inta jeer ee hawlgalka.Faa'iidada 77GHz waxay ku jirtaa saxsanaanteeda sare ee kala duwanaanta iyo cabbirka xawaaraha, xallinta xagal toosan oo wanaagsan, iyo mugga anteenada yar, waxaana jira faragelin yar.
Raadaarada-gaaban ayaa guud ahaan loo isticmaalaa in lagu beddelo dareemayaasha ultrasonic iyo taageeridda heerarka sare ee wadista iskeed u madaxbannaan.Si taas loo gaaro, dareemaha ayaa lagu rakibi doonaa gees kasta oo baabuurka, waxaana lagu rakibi doonaa dareemaha hore ee ogaanshaha fogaanta ayaa lagu rakibi doonaa dhinaca hore ee baabuurka.Nidaamka radarka ee buuxa ee 360° ee jidhka baabuurka, dareemayaal dheeraad ah ayaa lagu rakibi doonaa dhexda labada dhinac ee jidhka baabuurka.
Fikrad ahaan, dareemayaasha radar-ka ayaa isticmaali doona xadiga soo noqnoqda ee 79GHz iyo 4Ghz gudbinta xawaaraha.Si kastaba ha noqotee, heerka gudbinta soo noqnoqda calaamadaha caalamiga ah ayaa hadda u oggolaanaya kaliya 1GHz bandwidth kanaalka 77GHz.Maalmahan, qeexida aasaasiga ah ee radar MMIC (monolithic microwave integrated circuit) waa "3 kanaalka gudbinta (TX) iyo 4 kanaalada helaya (RX) waxay ku xiran yihiin hal wareeg".
Nidaamka caawinta darawalka ee dammaanad qaadi kara L3 iyo wixii ka sarreeya hawlaha wadista aan cidi wadin waxay u baahan yihiin ugu yaraan saddex habdhiska dareenka: kamarad, radar iyo ogaanshaha laysarka.Waa inay jiraan dhowr dareemayaal oo nooc kasta ah, oo lagu qaybiyey meelo kala duwan oo baabuurka, oo wada shaqeeya.Inkasta oo tikniyoolajiyadda semiconductor-ka loo baahan yahay iyo kamaradaha iyo tignoolajiyada horumarinta dareemayaasha radar hadda la heli karo, horumarinta nidaamyada lidar ayaa weli ah caqabadda ugu weyn uguna xasilloon marka loo eego arrimaha farsamada iyo ganacsiga.
