Imvamisa YomsakazoUbuchwepheshe (RF) buwubuchwepheshe bokuxhumana obungenantambo, obusetshenziswa kakhulu emsakazweni, kwezokuxhumana, kwi-radar, ekulawuleni kude, kumanethiwekhi ezinzwa ezingenantambo nakwezinye izinkambu. Umgomo wobuchwepheshe bemvamisa yomsakazo obungenantambo usekelwe kubuchwepheshe bokusabalalisa kanye nokuguqula kanye nokunciphisa amaza kagesi. Ngezansi ngizokwethula isimiso sobuchwepheshe bemvamisa yomsakazo obungenantambo.
Izimiso zobuchwepheshe
Ubuchwepheshe bemvamisa yomsakazo engenantambo buwubuchwepheshe obusebenzisa amaza omsakazo ukuxhumana. Amaza omsakazo empeleni awuhlobo lwamaza kagesi anemvamisa ethile kanye nobubanzi. Ekuxhumaneni kwemvamisa yomsakazo engenantambo, ukuphela kokudlulisa kuguqula amasignali olwazi abe amasignali wamaza kagesi ngamaza omsakazo bese ewathumela. Ingxenye eyamukelayo ithola amasignali wamaza kagesi bese iwaguqula abe amasignali olwazi ukuze kufezwe ukudluliswa kwedatha nokuxhumana.
Isimiso sesekethe sokwamukela nokudlulisa imvamisa yomsakazo
Izimiso zobuchwepheshe bemvamisa yomsakazo engenantambo zifaka phakathi izici ezilandelayo:
Ukuguqulwa kwemvamisa: Ekuxhumaneni ngemvamisa yomsakazo engenantambo, izimpawu zolwazi ziguqulwa zibe izimpawu zamagagasi kagesi zamaza akhethekile asekelwe kubuchwepheshe bokushintshashintsha. Izindlela ezivamile zokuxuba zifaka phakathi ukuxubana kwe-amplitude modulation (AM), ukuxubana kwemvamisa (FM), kanye nokuxubana kwe-phase modulation (PM).
I-Antenna: I-Antennaiyisici esibalulekile ekuxhumaneni ngemvamisa yomsakazo engenantambo. Isetshenziselwa ukuthumela nokwamukela izimpawu zamagagasi omsakazo. Ukwakheka nokubekwa kwama-antenna kuthinta ibanga lokudlulisela kanye nekhwalithi yokuxhumana okungenantambo.
I-antenna yophondo lwe-Broadband (1-18GHz)
I-Antenna Ejwayelekile Yokuthola Uphondo (4.90-7.05GHz)
I-Antenna Yempondo Ephindwe Kabili Eyindilinga Enezingqimba (2-18GHz)
I-RF Misoizincomo zomkhiqizo we-antenna
Ukubhala ikhodi nokubhala ikhodi yesiteshi: Ekuxhumaneni ngefrikhwensi yomsakazo engenantambo, ubuchwepheshe bokubhala ikhodi yesiteshi kanye nokubhala ikhodi busetshenziswa ukuthuthukisa ukuzinza kanye nokulwa nokuphazamiseka kokuxhumana nokuqinisekisa ukunemba kokuxhumana kwedatha.
Ukuphathwa kwamandla: Ukuxhumana ngemvamisa yomsakazo okungenantambo kudinga ukulungisa amandla okucindezela ukuqinisekisa ukuthi isignali ingadluliselwa ngaphakathi kwebanga elithile futhi ivimbele ukuthi ingathinti elinye.
Ukuphathwa kwebhendi yemvamisa: Ukuxhumana ngemvamisa yomsakazo okungenantambo kumele kuphathe kahle izinsizakusebenza ze-spectrum ukuze kugwenywe umthelela wezinsizakusebenza ze-frequency ezichithwayo futhi kuqinisekiswe ukuzinza nokuthembeka kokuxhumana.
Izimo zohlelo lokusebenza
Ubuchwepheshe bemvamisa yomsakazo obungenantambo busetshenziswa kabanzi emphakathini wanamuhla, buhlinzeka ngezinto eziningi ezilula kanye nokusungula izinto ezintsha empilweni nasemsebenzini wabantu. Nazi ezinye zezindawo ezivamile zohlelo lokusebenza lwe-RF olungenantambo:
Ukuxhumana kweselula: Isisekelo sokuxhumana ngeselula empeleni ubuchwepheshe bemvamisa yomsakazo, okuhlanganisa omakhalekhukhwini, amanethiwekhi angenantambo, ukuxhumana ngesathelayithi, njll. Lolu chungechunge lwamadivayisi ahlakaniphile luvumela abantu ukuthi benze izingcingo zezwi, bathumele imiyalezo, futhi bafinyelele i-inthanethi nganoma yisiphi isikhathi noma kuphi.
Ikhaya elihlakaniphile: Ezinhlelweni zekhaya ezihlakaniphile, njengezikhiye zeminyango ezihlakaniphile, izilawuli zokukhanyisa ezihlakaniphile, izinto zikagesi zasekhaya ezihlakaniphile, njll., ukulawula kude nokuphathwa okuhlakaniphile kungafinyelelwa ngobuchwepheshe obungenantambo.
I-inthanethi Yezinto: Ubuchwepheshe bemvamisa yomsakazo obungenantambo buyingxenye ebalulekile ye-Intanethi Yezinto. Buqaphela ukuxhumana phakathi kwamadivayisi ngamanethiwekhi ezinzwa angenantambo futhi buqaphela ukuqapha okuhlakaniphile, ukuqoqwa kwedatha kanye nokulawula okude.
Inethiwekhi yenzwa engenantambo: Kumanethiwekhi ezinzwa angenantambo, isetshenziswa kakhulu ekuqapheni imvelo, ezempilo yezokwelapha, ekulawuleni izimboni nakwezinye izinkambu ukuze kufezwe ukuqoqwa kwedatha kanye nokuqapha ngesikhathi sangempela.
Imishini yokulawula kude engenantambo: Ubuchwepheshe bemvamisa yomsakazo obungenantambo busetshenziswa kabanzi kumaphaneli okulawula afana nezilawuli ezikude ze-TV, izilawuli zezimoto, kanye nezilawuli zamamodeli ukuze kuqedwe imisebenzi ekude.
Uhlelo lwe-radar: Umsakazoubuchwepheshe bemvamisa budlala indima ebalulekile ezinhlelweni ze-radar futhi busetshenziselwa ukuthola okuqondiwe, ukulandelela kanye nokuzulazula. Busetshenziswa kabanzi ezindiza, i-meteorology kanye neminye imikhakha.
Ukusetshenziswa kobuchwepheshe bemvamisa yomsakazo obungenantambo kubanzi kakhulu, kuhlanganisa izinkambu eziningi, njengokuxhumana kweselula, ukuxhumana ngesathelayithi, izinhlelo ze-radar, izilawuli ezikude, amanethiwekhi ezinzwa ezingenantambo, njll. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ubuchwepheshe bemvamisa yomsakazo obungenantambo buzoqhubeka nokudlala indima ebalulekile emikhakheni eyahlukahlukene, buletha ukulula kanye nokusungula izinto ezintsha empilweni nasemsebenzini wabantu.
Ukuze uthole ulwazi olwengeziwe sicela uvakashele:
