Radar - yintoni na le nto? isimiso ukusebenza

Radar - igajethi electronic compact ukuba uyakwazi ukubona aze azise umnini malunga indlela yokuhamba kweenkqubo lokuzala kwezithuthi. Iinkqubo ezinjalo bukhazimle laser okanye amaza erediyo, ukumisela ukuba ngowuphi na uhlengahlengiso. Oko kukuthi, radar - olu luhlobo yomfumani elisebenza nge yokufaka imiyalezo.

Kukho iindlela eyimpumelelo esebenzayo. ZifunwaEzokugqibela zidweliselwe ngokuba radar detectors kunye feature zazo eziphambili - isizukulwana eliphezulu-power uphazamiseko kwi Iindlela Ubhaqo yezithuthi. Usebenza izixhobo ezinjalo spectrum ethile kunomathotholo okanye ukuliguquguqula ngqo uphawu impendulo, leyo ngamandla mkhulu lee obizwa yokuqala.

Ngenxa yoko, iinkqubo / yerada endlela izakuvela okanye modulated yoko, okanye abayi ancanyathiselwa yi nto konke konke. radar enjalo - oku kukwaphula ngqo umthetho, kwimeko ilungileyo, uza kufumana isohlwayo kunye kohluthwa igajethi, yaye okubi - nobutyala. Ngenxa yoko, abayi kuqwalaselwa, uze uchaze iipatheni wavumela, ezo zibizwa ngokuba detectors.

Normal radar kakutsha - yinto akwamkele nje, nto leyo kufihla kwaye modulates nemiqondiso ethwele iinkqubo izithuthi ezifana radar tshin, kodwa ivumela kuphela ukuba ukwazi umnini indlela yabo / ubukho.

abenzi

Emarikeni wolu hlobo izixhobo wemoto kukukhokela ngaphantsi iintlobo kweshumi. Kusenokwenzeka ukuba kuqatshelwe le nkampani Whistler, okugada, yerada tshin Sho kum, «Cobra" yaye "Beltroniks". Ngoko ke, eneneni, esiyintsika yale abalimi ibali onesidima, ogama lakhe waba ngundaba ukuba izinto isicwangciso enjalo.

Kukho nezinye iinkampani ngaphantsi ezaziwayo-kakuhle, kuluhlu leyo kuzo zonke izixhobo smart, kodwa apha ufuna uphendlo elungileyo kwaye izinto ezininzi ukuze uzihlaziye ngaphambi kokuba bathenge. Ezi ziquka "yunidom», STR radar (Storm Street), Rocky Intaba kunye PNI.

Ngokubhekiselele kwintsimi yethu, kubathengi basekhaya bakhetha imizekelo ngaphezulu okanye ngaphantsi ngokomgangatho naphaya phantsi zokwenene yethu Moongoose iinkampani "SIMICON", "nevedimku" kunye izizukulwana elidlulileyo le ihloniphekile "Cobra." Kuya ngokuya ngokukhawuleza kuthandwa eRashiya uphawu Radartech, ogama zingaba ukubona i "Arrow" notorious.

Kukho izinto ezingaqhelekanga kakhulu izinto ezinjalo, nto leyo sithuthi kunye indima ekhethekileyo ingadlali ngathi imodeli 24-Flight radar, ukukwazi ukulandelela moya-intanethi. Into emnandi kwezinye iimeko, kodwa wasinda wagxila kakhulu.

isimiso ukusebenza

traffic System ethwele kwi indlela yomsebenzi reflection, oko kukuthi, isantya ulinganiswa yi kwimitha leyo iboniswa ukusuka emotweni yakho. Lo myalezo uya ingacota kunendlela umgca ngqo, esebenzisa kakutsha radar, nto leyo ethetha ukuba umqhubi ziya kwaziswa kwangethuba phambi lokuzala ngexesha phindo.

Xa imozulu intle, kwakunye emaphandleni, unako ukufumana inkqubo yezithuthi kumgama oziimitha 5000, yaye ezona premium radar uyakwazi ukubamba ngumqondiso ukuya ku-10 000 m, nkqu onduli sezwe.

Ngenxa yokuba uninzi nale indlela yezithuthi eyenzelwe 300-500 metres ukufunda ezizinzileyo, radar, sinokuthi ngaphandle ezama, ukuze tufwile ukuba ubukho isithuba DPS.

Kukho kwakhona elinye iintlobo olu hlobo iteknoloji - GPS-radar. Apha umgaqo osebenza into eyahlukileyo. Ukuba kakutsha ibandakanyeka ebizwa ngqo inkqubo Ubhaqo yezithuthi vperedistoyaschego, i-GPS-isixhobo kuthathela data imephu akhawunti, oko kukuthi, kwizikhundla ngqo ephawulweyo kunye namagumbi yesithuthi ecaleni komgca online.

radar enjalo ifuna rhoqo (okanye kufutshane kuyo) kwikhonkco satellite yokubonisa data ubuninzi ethembekileyo. Option kakhulu lale, kodwa kuphela xa umqondiso uzinzile yaye akafuni ndinyamalale ixesha elide xa ihamba-hamba kwingoma. Ukuba unxibelelwano kunye yesathelayithi idla emlonyeni okanye musa, ngoko ufumana nje igajethi entle kwiqela lenjongo, endaweni radar.

Ukuphonononga ze abanikazi ngezinto ezifana ukulalana nezixhobo, kwaye baxhomekeke ubukhulu becala phezu bokuqonda zemozulu bommandla othile. Wena indawo enkangala sunny - ziya kusebenza phantse nasiphi kakutsha radar, badla ezintabeni okanye yimvula - i-GPS-isixhobo iya kuba ukhetho best.

Njengoko ngokuba izimvo imodeli ezithile radar, kunzima kakhulu ukuba lokuhlela ngenxa ezahlukeneyo abenzi, imigca, kunye nothotho zobuchwepheshe ngokwabo. Noko ke, kusenokwenzeka ukuba ukulandela ncomo mkhuba, nto leyo kubonakaliswa ilungileyo athi: ". Le ezibiza kakhulu ngcono"

yokukhulisa

Zonke detectors radar (kwi esemoyeni) ngenxa iimpawu zayo usebenzisa yokukhulisa umqondiso, nto leyo kuyandisa kakhulu uluhlu yomsebenzi wabo. Zizonke ekuchazeni iintlobo ezimbini yokukhulisa enjalo - ngqo kunye heterodyne-based (ngamanye amaxesha kunye isimaphambili "super").

yokukhulisa ngqo

Yeyona ndlela elidala kunawo eziqhelekileyo ukuze sifumane kwicandelo likarhulumente. Enye yezinto ezilungileyo kule ndlela - le passivity elililo, oko kukuthi, i-radiation lo mnqongo kufutshane kangangoko zero. Kumazwe apho izixhobo akuvumelekanga ukusuka igajethi kunye ngombhobho akuyomfuneko kwibhodi isithuthi kwezinye Izivumelwano uvimba, afana VG-2.

Ukongeza, yokukhulisa ngqo kakutsha ishenxisa ingxolo ezininzi, ngoko ukuba nandzu uvakalelo encinane ngecebo. Isuphu yesicwangciso Kulula kakhulu ukuba amise kwaye abe ithegi ixabiso yentando yesininzi.

abenzi aseYurophu kudala iqalile ukuba bashiye izisombululo ezinjalo ngenxa ngempumelelo yabo, kodwa abasebenzi basemakhitshini basaqhubekeka ukugcwalisa up imoto kunye elektroniki yokukhulisa ezinjalo.

LO sesimangalo

Le ndlela kakhulu ngcembe ngaphezu inzuzo kunye kakhulu ndikhulile isigama. Ezi modyuli baqhele ukubona ngendlela eziqhelekileyo premium iimodeli radar detectors. inzuzo engenakuphikiswa le inzuzo - uvakalelo oluphezulu kunye Ukukhetha elungileyo ezitsho zokusebenza.

Oku kungenziwa ngokuba kakhulu into yokuba ifowuni kunye umnqongo oscillator wengingqi iyasebenza, oko kukuthi radar ngexesha lokusebenza liqala ukuba kukhutshwe kwamaza isici. Ukongeza, ubukho ingxolo ngexesha ukusetyenziswa ngamanye amaxesha iphazamisane kakhulu ngesiqhelo functionality kwefowuni. Cwangcisa i isixhobo eso similise okwaloo adventure ngokwenene kwiisekethe isebe kunye rhoqo selectivity.

Kwakhona, zodwa kubalulekile ukuphawula ukuba izixhobo kule hlobo zithintelwe ngumthetho kwamanye amazwe. Phambi kokuba eRashiya, inkqubela asikafikeleli, ngoko kummandla heterodyne yerada tshin yethu ingasetyenziswa ngaphandle kokoyika ahlawuliswe. Ezi umsakazo eqolo, kodwa kuyaphawuleka ukuba kuyanceda ngokukhawuleza kakhulu, ingakumbi xa usoloko ukuqhuba koohola bendlela, motorways nkqu ukujikeleza lizwe.

Iyunithi processing uphawu

Le yunithi, enyanisweni, intliziyo naluphi radar. Kukho kwenzeka inkqubo amaza engenayo evela eriyali kwaye utsale abenzi. Oko kukuthi, ngokusekelwe ezinye ubuchule bakhe, ifowuni kwiinkqubo ulwazi kwaye ulunika kumsebenzisi ngendlela efanelekileyo. Namhlanje, usebenzisa ezahlukeneyo emininzi enjalo classifiers - analog, digital hybrid.

analog

Indlela elula analog kancinci shwaka, enika indlela ibhastile kunye nezixhobo zedijithali. Olu nyango isekelwe phezu iisekethe sele ebekwe phantsi chip, ukuba apelwa ubuchule.

Ilishwa apha zisekuhleni kwaye zibaluleke kakhulu: Izinga eliphezulu ingxolo kunye isiphoso, ngesantya encinane kakhulu nokuselwa omkhulu ngelo xesha.

yedijithali

Indlela lwedijithali nathembisayo ngokwemigaqo yokusebenza. Radar detectors yale hlobo zixhotyiswe nge isilawuli kunye nobuninzi VLSI (isikali elikhulu kakhulu iziphaluka ehlangeneyo), apho wabeka ubunzima nemiboniso kunye ubuchule ezintsonkothileyo, kunye nomgaqo nokusebenza kwisixhobo ezisekelwe kwi heuristics evumela maxa wambi ukuze kuzakwandisa isantya isixhobo.

Software, nto leyo isetyenziswa radar zedijithali kwenziwa ngukutsha, yaye ngaloo ndlela kuphuculwe ukusebenza tshin, ukudibanisa ubuchule omtsha kuluhlu okhoyo. Ukongeza, indlela esibonakala positives zobuxoki ncinane, kwaye umlinganiselo uphazamiseko lifinyele ku nothi. Kwakhona ukongeza indawo kakhulu enkulu isicelo (Imiqondiso ngaxeshanye ukuya ezisibhozo) isixhobo kunye nokusebenza ngaxeshanye. Ngokutsho Abaqhubi otzіvam olu hlobo kwezixhobo kakhulu kakuhle ngaphezu analog.

hybrid

izinto Hybrid zezona ixhaphake kakhulu kwintsimi yethu. Umgaqo ekusebenzeni sixhobo ilula kwaye kucacile kwisihloko. Ngoko ke bambi analog block, kodwa amathuba "amanani". izixhobo ezinjalo ngaphezulu okanye ngaphantsi impendulo ngokukhawuleza kwaye umthamo omncinane signal, oko kukuthi uphazamiso.

Phantse zonke radars ezishelfini engoovimba zalapha kweli candelo umntu avareji ukusebenza ithekhinoloji gqith. Njengoko kucacisiwe ncomo abasebenzisi abaninzi, "ngesazobe", ke, kulungile, kodwa iyabiza kwaye kufuneka akuhambise rhoqo, kwaye hybrids nabalulamileyo yaye ubhetyebhetye.
