Radar ya microwave y'imodoka ni iki?
Radar ya mikoroonde y'imodoka ni sisitemu ya radar ikoresha mikoroonde mu gutahura, cyane cyane ikoreshwa mu modoka n'izindi modoka zigendera ku butaka. Radar ya mikoroonde imenya ibintu biri mu bidukikije yohereza kandi ikakira ibimenyetso bya mikoroonde, kugira ngo igere ku nshingano zitandukanye, nko kumenya imbogamizi, kuburira kugongana, kugenzura ingendo zo mu mazi zihindagurika, nibindi
Ihame ry'imikorere
Radar ya mikoroonde y'imodoka ikora nk'iya radar isanzwe, ni ukuvuga ko yohereza umuraba udafite umugozi (mikoroonde) hanyuma ikakira ijwi hakurikijwe itandukaniro ry'igihe hagati yo kwakira no kwakira, kugira ngo ipime amakuru y'aho intego iherereye. By'umwihariko, radar za mikoroonde zisohora ibimenyetso bya mikoroonde bisubira inyuma iyo zihuye n'imbogamizi, kandi radar ibara intera ipima igihe cy'urugendo rw'ibimenyetso. Byongeye kandi, radar ya mikoroonde ishobora kandi kumenya umuvuduko n'icyerekezo cy'ikintu isesengura imiterere y'ikimenyetso cyagaragajwe, nk'ingaruka za Doppler .
Imiterere y'ikoreshwa
Radar ya mikoroonde y'imodoka ifite uburyo butandukanye bwo kuyikoresha mu modoka:
Umuburo ku impanuka: mu kumenya inzitizi ziri imbere, gutanga umuburo hakiri kare, fasha umushoferi gufata ingamba zo kwirinda impanuka.
Uburyo bwo kugenzura ubwato bugendana n'imodoka: Ihindura umuvuduko w'uburyo bwo kugenzura ubwato bugendana n'imodoka bitewe n'aho ikinyabiziga giherereye, ikarinda intera iri hagati y'imodoka iri imbere.
Gutahura abanyamaguru: Muri sisitemu yo gutwara imodoka yikora, radar ya mikoroonde ishobora kumenya abanyamaguru n'izindi mbogamizi kugira ngo irinde umutekano w'abatwara.
Guparika imodoka mu buryo bwikora: Fasha imodoka kubona aho iparika imodoka ikwiye mu mwanya wayo no kurangiza imirimo yo guparika imodoka.
Ibipimo bya tekiniki n'imiterere y'imikorere
Radar za mikoroonde zikoresha imodoka zisanzwe zikora mu miyoboro y'amazi ya milimetero, nka 24GHz, zifite frequencies nyinshi n'uburebure bw'umurambararo bugufi. Ibi bituma radar ya mikoroonde igira icyerekezo cyo hejuru n'ubushobozi bwo kumenya neza intego zo hafi. Byongeye kandi, radar ya mikoroonde ntigira ingaruka ku kugaragara neza kandi ishobora gukora mu buryo busanzwe mu bihe bibi by'ikirere. Ariko, ikiguzi cya radar ya mikoroonde kiri hejuru, kandi ubushobozi bwo kumenya ibintu bito ntabwo ari bwiza nka lidar .
Imirimo y'ingenzi ya radar ya microwave y'imodoka irimo ibi bikurikira:
Ubuhanuzi ku impanuka no gufunga feri mu buryo bwikora (AEB): Radar za mikoroonde zibona inzitizi imbere kandi byaba ngombwa zigatera sisitemu yo gufunga feri mu buryo bwikora kugira ngo hirindwe impanuka.
Gutahura abanyamaguru: Binyuze muri microwave radar, imodoka zishobora kumenya no gutahura abanyamaguru, bityo bikanoza umutekano w'abatwara ibinyabiziga.
Igenzura ry'ahantu hatabona n'umuburo wo guhaguruka k'umuhanda: radar ya mikoroonde ishobora kugenzura ahantu hatabona k'imodoka kugira ngo hirindwe kugongana n'izindi modoka mu gihe cyo guhindura inzira, kandi ishobora kugenzura aho inzira iva no kumenyesha abashoferi.
Uburyo bwo kugenzura ubwikorezi bw’imodoka (ACC): Radar ya mikoroonde ishobora gufasha imodoka kugumana intera iri hagati yazo n’imodoka imbere y’uburyo bwo kugenzura ubwikorezi bw’imodoka bw’imodoka.
Ubuhanuzi bw'imodoka inyuma (RCTA): radar ya mikoroonde ishobora kugenzura urujya n'uruza rw'imodoka inyuma y'ikinyabiziga, ikibutsa umushoferi kwitondera imodoka iri imbere, kugira ngo wirinde gusubira inyuma kugongana.
Ihame ry'imikorere ya radar ya mikoroonde ni ugupima aho intego iherereye wohereza imiraba idafite umugozi (imiraba ya radar) no kwakira ijwi hakurikijwe itandukaniro ry'igihe hagati yo kohereza n'iyakira. Inshuro radar ya millimeter wave iri mu gice cy'umuraba wa millimeter, bityo yitwa millimeter wave radar .
Ikoreshwa ry'imirongo itandukanye ya radar ya mikoroonde mu modoka irimo imirongo ibiri ya 24GHz na 77GHz. Radar za 24GHz zikoreshwa cyane cyane mu gutahura intera ngufi, mu gihe radar za 77GHz zifite ubushobozi bwo kureba kure n'ingano nto, zikwiriye mu kumenya intera ndende .
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
Zhuo Meng Shanghai Auto Co, Ltd. yiyemeje kugurisha ibice by'imodoka bya MG&750 irahari kugura.
