millimeter-wave radar (MMW radar) thiab LiDAR yog ob qho tib si siv hauv tsheb sensing systems, tab sis lawv muaj qhov sib txawv ntawm cov qauv kev ua haujlwm, kev muaj peev xwm, thiab kev siv.
Txoj Cai Ua Haujlwm
millimeter -Wave Radar (MMW Radar):Siv xov tooj cua nthwv dej hauv millimeter -wave zaus ntau yam (feem ntau 24 GHz, 77 GHz, lossis 79 GHz) txhawm rau txheeb xyuas cov khoom los ntawm kev ntsuas lub sijhawm ncua sijhawm thiab Doppler hloov ntawm cov teeb liab pom.
LiDAR (Lub Teeb Pom Kev thiab Ntau Yam):Siv cov kab teeb ci laser (feem ntau yog nyob ze -infrared spectrum) los soj ntsuam qhov chaw nyob ib puag ncig thiab tsim kom muaj - daws teeb meem 3D daim ntawv qhia los ntawm kev ntsuas lub sij hawm nws yuav siv sij hawm rau lub teeb rov qab los tom qab ntaus ib yam khoom.
Kev kuaj pom ntau thiab qhov tseeb
NWS Radar:Muaj qhov ntsuas ntev ntev (txog 250m), ua tau zoo nyob rau hauv cov huab cua tsis zoo ( nag, huab cua, plua plav), tab sis muaj kev daws teeb meem qis dua thiab tawm tsam nrog cov khoom me me.
LiDAR:Muab siab - daws teeb meem 3D duab nrog cov khoom raug kuaj pom thiab pom cov duab tab sis muaj qhov luv luv (feem ntau 100-200m) thiab tuaj yeem cuam tshuam los ntawm huab cua hnyav thiab tshav ntuj muaj zog.
Daim ntawv thov hauv Tsheb
NWS Radar:Feem ntau siv rau Adaptive Cruise Control (ACC), Blind Spot Detection (BSD), thiab Collision Avoidance systems.
LiDAR:Feem ntau yog siv rau kev tsav tsheb tsis muaj zog thiab tsav tsheb siab heev-cov txheej txheem kev pabcuam (ADAS) vim nws cov ntaub ntawv ntxaws txog ib puag ncig.
Nqi thiab complexity
NWS Radar:Tus nqi ntau dua -zoo, compact, thiab dav siv nyob rau hauv ntau lawm tsheb.
LiDAR:Ntau kim thiab complex, tab sis nws cov nqi yog txo nrog kev nce qib hauv technology.
Hauv cov ntsiab lus, MMW radar yog qhov zoo dua rau qhov ntev - nrhiav kom pom thiab ua haujlwm hauv txhua qhov huab cua, thaum LiDAR muab cov kev daws teeb meem zoo dua thiab paub txog cov khoom, ua rau nws zoo tagnrho rau siab - qib kev siv tsav tsheb.
