Radar - Iyini? Umgomo we operation

Radar - compact igajethi electronic ukuthi uyakwazi ukuthola sazise umnikazi mayelana kokuqondisa yezokuvakasha traffic eziveza izinhlelo. izinhlelo ezinjalo ezishisa kakhulu zikhipha izinhlayiyana laser imisebe noma amaza omsakazo, ukucacisa kwalokho kushintshwe. Okungukuthi, abangabantwana radar - lena uhlobo umamukeli ukuthi isebenza nge amasignali input.

Kukhona amamodeli yekwentiwa kanye asebenzayo. Laba okuthiwa kubafuni futhi isici yabo eyinhloko - isizukulwane ephezulu amandla ukuphazamiseka ukuze traffic ukuthola izinhlelo. Usebenza amadivayisi anjalo spectrum ezithile zomsakazo noma ngqo modulate isignali impendulo, okuyinto emandleni uphakeme ngaphezu sihlobene yasekuqaleni.

Ngenxa yalokho, izinhlelo / radar amaphoyisa omgwaqo izovela noma modulated yalokho, noma ngeke aqoshiwe by lutho nhlobo. radar okunjalo - lena wephula umthetho, okuyinto kuleli cala engcono, uzothola enhle futhi ekuphucweni gajethi, futhi neze - necala lobugebengu. Ngakho-ke, ngeke kucatshangelwe, futhi uchaze amaphethini kuvunyelwe, ababiziweyo imitshina.

Jwayelekile radar umtshina - kuyinto umamukeli yokwenziwa, engesiyo mutes futhi modulates amasignali nithela izinhlelo traffic ezifana radar umtshina, kodvwa kuvumele kuphela ukwazi umnikazi yokusondela kwabo / khona.

abakhiqizi

Ezimakethe yalolu hlobo kwemishini for imoto ehamba phambili esingaphansi brand kweshumi. Kungaphawulwa inkampani Whistler, okugada, radar umtshina Sho Me, «Cobra" futhi "Beltroniks". Kuyinto, eqinisweni, umgogodla abakhiqizi indaba ehloniphekile, ogama lakhe baba nesifenqo ngokuba amagajethi we plan onjalo.

Kukhona nezinye izinkampani kancane owaziwa, in the uhla lapho kuwo wonke amadivayisi smart, kodwa lapha udinga wosesho omuhle futhi izinto eziningi ukuba uhlole ngaphambi kokuthenga. Lezi zihlanganisa "yunidom», Str radar (Street Storm), Rocky Mountain futhi PNI.

Ngokuphathelene nawo saya esabelweni sethu, abathengi yasekhaya uncamela ucishe onobuhle qualitatively ingashintshwa ngaphansi ezingokoqobo yethu esuka Moongoose izinkampani "SIMICON", "nevedimku" futhi izizukulwane the zihlaba esidlule "Cobra." It is ngokushesha kuyanda eRussia brand Radartech, ogama amadivayisi angathola esasinedumela elibi, "Umcibisholo".

Kukhona futhi izinto eziyinqaba ngaphezulu amagajethi afana, okuyinto abahamba ngezimoto kanye nendima edlalwa yi-ekhethekile akusho adlale like a imodeli 24-Flight radar, ikhono ukulandelela izindiza online. Into emnandi kwezinye izimo, kodwa kugxilwe kancane kakhulu.

Umgomo we operation

System traffic ebizwa ngokuthi isibonelo umsebenzi reflection, okungukuthi, ijubane kukalwa emisebeni elisobala kusuka emotweni yakho. Lokhu isignali uya kancane kuka emgceni locondzile, olusebenzisa umtshina radar, okusho ukuthi umshayeli bazokwaziswa kusenesikhathi ukuba khona sihlobene ngokuhamba ukuphindaphinda.

Uma isimo sezulu muhle, kanye emaphandleni, ungathola uhlelo womgwaqo at ibanga 5000 metres, kanye best premium radar uyakwazi ukubamba uphawu kwabangu-10 000 m, ngisho sezwe elinamagquma.

Sikhishwe yokuthi iningi traffic isiqondiso uzitholele eyenzelwe 300-500 metres ukufundwa uzinzile, radar, singasho ngaphandle zingaphazamisi, ukukuxwayisa khona iposi ka DPS.

Kukhona omunye ezihlukahlukene lolu hlobo ubuchwepheshe - GPS-radar. Lapha isimiso wokusebenza abaphila ngayo ihluke ngokuphelele. Nxa idetector ukwenza ngaphandle sihlobene ngokuqondile ka vperedistoyaschego traffic ukuthola uhlelo, GPS-kudivayisi ucabangela idatha imephu akhawunti, okungukuthi, isikhundla esiqondile uphawu futhi emakamelweni imoto agudle inthanethi.

radar okunjalo kudinga njalo (noma eduze kuyo) ngesimiso esixhunywe ngesiphuphutheki kokubonisa idatha esiphezulu okuthembekile. Inketho ngempela asebenzayo, kodwa kuphela uma isignali uzinzile futhi ingabe usekhona isikhathi eside uma ezihambayo emhlabeni ithrekhi. Uma ukuxhumana satellite ngokuvamile kuphazamisekile noma bakhe bashona, khona-ke nje uthole igajethi nice iphaneli, esikhundleni radar.

Izibuyekezo wabanikazi ku leyo mishini ukungabi nasimilo, futhi kuncike kakhulu ku-ezicashile zezulu of endaweni ethize. Wena futhi libalele enkangala endaweni - uzosebenzisana cishe kunoma iyiphi umtshina radar, bavame ukuya ezintabeni noma emvuleni - GPS-idivaysi yakho ngeke ukhetho best.

Ngokuqondene nokukhulumela ngohlelo imodeli ethile radar, kunzima kakhulu ukuze uhlukanise ngenxa ezihlukahlukene abakhiqizi, imigqa, uchungechunge amagajethi ngokwabo. Noma kunjalo, kungenzeka ukulandela Izibuyekezo mkhuba, okuyinto engcono esashiwo inkulumo ethi: ". I ezibizayo ngcono"

yokukhulisa umsindo

Zonke imitshina radar (phezu airwaves) ngenxa izici zayo abe asebentisa timphawu yokukhulisa umsindo, okuyinto ukwandisa kakhulu uhla umsebenzi wabo. Ubude kungenzeka ukuqoka ezimbili izinhlobo okhulisa ezinjalo - eqondile Heterodyne ezisekelwe (kwesinye isikhathi isiqalo "super").

okhulisa oqondile

Kuyindlela endala futhi ajwayeleke kunawo wonke ukuba bathole engxenyeni kahulumeni. Enye yezinzuzo zale nqubo - the passivity ngokuphelele, okungukuthi, emisebeni module eduze ngangokunokwenzeka zero. Emazweni lapho imishini enjalo elivinjelwe ukuba igajethi nge-amplifier ayidingekile ebhodini imoto kwezinye yezifiso Ukuvinjwa, ezifana VG-2.

Ngaphezu kwalokho, okhulisa ngqo umtshina aqede umsindo kakhulu, ukuze iphutha kucikelela encane zedivayisi. Isobho of plan Kulula kakhulu usethe futhi ube price tag yeningi kakhulu.

Sekuyisikhathi eside abakhiqizi European kuqalile ukulahla izixazululo ezinjalo ngenxa nokusebenza kahle yabo ongaphakeme, kodwa abasebenzi basezindlini bazoqhubeka ukugcwala emakethe imoto nge amagajethi yokukhulisa umsindo enjalo.

LO amplifier

Le ndlela kuyinto okuqhubekayo okungaphezu inzuzo futhi eziphambili kakhulu e matemu. Lezi amamojuli bajwayele ukubona ngendlela eyejwayelekile futhi premium amamodeli we kubafuni. inzuzo elingenakuphikwa lokhu inzuzo - kucikelela okusezingeni eliphezulu nokukhetha ezinhle yokusebenza amaza.

It kungenziwa ngokuthi ezibucayi iqiniso lokuthi kudivayisi wendawo oscillator module iyasebenza, ie radar ngesikhathi ukusebenza uqala ezishisa kakhulu zikhipha izinhlayiyana isici wavelength. Ngaphezu kwalokho, ukuba khona umsindo ngesikhathi ukusetshenziswa ngezinye izikhathi kuphazamisa kakhulu nge ukusebenza evamile zedivayisi. Isethaphu of into enjalo uguqulwe adventure real, banakekele izifunda Izakhiwo zegatsha futhi imvamisa selectivity.

Futhi, eceleni Kuyaphawuleka ukuthi izinsimbi lolu hlobo kuyangqubuzana nomthetho kwamanye amazwe. Ngaphambi Russia, intuthuko enjalo baye akukafiki, ngakho insimu Heterodyne yethu radar umtshina ingasetshenziswa ngaphandle kokwesaba ahlawuliswe. Lawa magajethi akuzona ezishibhile, kodwa kungokuphawulekayo ukuthi usuthela ngokushesha okukhulu, ikakhulukazi uma ngokuvamile ukushayela on imigwaqo, motorways ngisho ukuhamba ezweni lonkana.

Isignali processing unit

Le yunithi is, eqinisweni, yilokho nhliziyo radar. Kube kwenzeka inqubo amasignali engenayo kusukela antenna kanye izinzwa. Okungukuthi, esekelwe ezinye algorithm yakhe, idivayisi icubungula ulwazi kanye ulunika umsebenzisi nangendlela efanele. Namuhla, usebenzisa ezahlukeneyo eziningana ezifana isignali classifiers - analog, digital futhi hybrid.

analog

Indlela elula of analog ziyanyamalala kancane kancane, yadedela nzalo kanye namadivayisi digital. Lokhu kwelashwa kusekelwe izifunda kakade wabeka phansi chip, ukuthi kubhalwe algorithm.

Okumbi nazi esobala ezibucayi: izinga eliphezulu umsindo futhi ngephutha, isivinini encane kakhulu futhi eliphezulu ukusetshenziswa zamanje.

digital

Indlela digital iyona ethembisayo ngokuya ezihlukahlukene zokusisebenzisa. Abatholi be-radar yalolu hlobo anemisila microprocessor kanye sebuningini VLSI (ngezinga elikhulu kakhulu izifunda okuhlangene), lapho wabeka zimo isisindo nge algorithm eziyinkimbinkimbi, nesimiso okusebenzela thuluzi esekelwe heuristics evumela ngezinye izikhathi ukwandisa isivinini kudivayisi.

Software, okuyinto esetshenziswa radar digital kungenziwa ngcono, futhi ngaleyo ndlela ngcono ukusebenza idetector, unezela algorithm entsha ohlwini olukhona. Ngaphezu kwalokho, indlela ebonakala positives bamanga ongatheni, kanye nenani ukuphazamiseka kuyehla kube zero. Singasho futhi wengeza endaweni kakhulu enkulu isicelo zedivayisi nokucubungula okuhambisanayo (kufika ku eyisishiyagalombili amasignali kanyekanye). Ngokusho abashayeli otzіvam yalolu hlobo imishini esebenza kahle kakhulu ukwedlula analog.

hybrid

amagajethi Hybrid kuyizinto ezivamile abasensimini yethu. Umgomo we operation sedivayisi ezifana ulula futhi kucace kusuka isihloko. Ngakho sinesizathu ezinye block analog, kodwa amathuba "izinombolo". amadivaysi ezinjalo ucishe ukusabela ngokushesha futhi esincane kube lezitshengiselo zamanga ezinengi, okungukuthi isiphazamiso.

Cishe zonke radars emashalofini ezitolo zendawo emkhakheni umuntu ovamile abasebenza ngobuchwepheshe hybrid. Njengoba kushiwo izibuyekezo abasebenzisi eziningi, "isibalo" Yiqiniso, kuhle, kodwa kuyabiza futhi udinga ukukhonza ke kaningi, futhi nzalo kukhona linesizotha futhi uyisithelo esiyisimanga.
