I-Radio Frequency(RF) ubuchwepheshe ubuchwepheshe bokuxhumana obungenawaya, obusetshenziswa kakhulu emsakazweni, ezokuxhumana, e-radar, ekulawulweni kude, amanethiwekhi wezinzwa ezingenantambo kanye neminye imikhakha. Umgomo wobuchwepheshe befrikhwensi yomsakazo ongenazintambo usekelwe ekusabalaliseni nasekushintsheni nasekunciphiseni ubuchwepheshe bamagagasi kagesi. Ngezansi ngizokwethula isimiso sobuchwepheshe befrikhwensi yomsakazo ongenazintambo.
Izimiso zobuchwepheshe
Ubuchwepheshe befrikhwensi yomsakazo okungenantambo ubuchwepheshe obusebenzisa amaza omsakazo ukuxhumana. Amaza omsakazo empeleni awuhlobo lwamaza kagesi anamaza nobubanzi obuthile. Ekuxhumaneni kwamaza omsakazo okungenazintambo, isiphetho sokudlulisa siguqula amasiginali olwazi abe amaza kagesi kagesi ngamaza omsakazo bese ewathumela ngaphandle. Indawo eyamukelayo ithola amasignali amaza kagesi bese iwaguqula abe amasignali olwazi ukuze kuzuzwe ukudluliswa kwedatha nokuxhumana.
Umgomo wesekethe wokwamukela nokudlulisa irediyo
Izimiso zobuchwepheshe befrikhwensi yerediyo ihlanganisa ikakhulukazi izici ezilandelayo:
Ukushintshwa kwemvamisa: Ezokuxhumana kwefrikhwensi yomsakazo okungenantambo, amasignali olwazi aguqulwa abe amaza kagesi amaza akhethekile asuselwe kubuchwepheshe bokumodulation. Izindlela ezijwayelekile zokuhlanganisa zifaka i-amplitude modulation blending (AM), i-frequency modulation blending (FM), kanye ne-phase modulation blending (PM).
I-Antenna: I-Antennaiyingxenye ebalulekile yezokuxhumana kwamafrikhwensi omsakazo. Isetshenziselwa ukuthumela nokwamukela amaza omsakazo. Ukwakheka nokubekwa kwezinti kuthinta ibanga lokudlulisela kanye nekhwalithi yokuxhumana okungenantambo.
I-antenna yophondo olubanzi (1-18GHz)
I-Standard Gain Horn Antenna(4.90-7.05GHz)
I-Conical Dual Polarized Horn Antenna(2-18GHz)
RF Misoizincomo zomkhiqizo we-antenna
Ukubhala amakhodi kwesiteshi nokuqopha: Ekuxhumaneni kwamafrikhwensi omsakazo okungenantambo, ubuchwepheshe bokubhala amakhodi wesiteshi kanye nokuqopha busetshenziselwa ukuthuthukisa ukuzinza kanye nokulwa nokuphazamiseka kokuxhumana nokuqinisekisa ukunemba kokuxhumana kwedatha.
Ukuphathwa kwamandla: Ukuxhumana kwefrikhwensi yomsakazo okungenantambo kudinga ukulungisa amandla okucindezela ukuze kuqinisekiswe ukuthi isignali ingadluliswa phakathi kwebanga elithile futhi ivimbele ukuthi lingaphazamisi elinye.
Ukuphathwa kwebhendi yemvamisa: Ukuxhumana kwamafrikhwensi omsakazo okungenantambo kufanele kuphathe kahle izinsiza ze-spectrum ukuze kugwenywe umthelela wokumoshwa kwezinsiza zebhendi yefrikhwensi futhi kuqinisekiswe ukuzinza nokwethembeka kokuxhumana.
Izimo zohlelo lokusebenza
Ubuchwepheshe befrikhwensi yomsakazo okungenantambo busetshenziswa kakhulu emphakathini wanamuhla, buhlinzeka ngokunethezeka okuningi kanye nokuqanjwa okusha kwezimpilo zabantu nomsebenzi. Nazi ezinye izindawo ezivamile zohlelo lokusebenza lwe-RF engenantambo:
Ezokuxhumana ngomakhalekhukhwini: Isisekelo sokuxhumana kwamaselula empeleni ubuchwepheshe befrikhwensi yomsakazo, okuhlanganisa omakhalekhukhwini, amanethiwekhi angenawaya, ukuxhumana ngesathelayithi, njll. Lolu chungechunge lwamadivayisi ahlakaniphile avumela abantu ukuthi benze izingcingo zezwi, bathumele imilayezo yombhalo, futhi bafinyelele i-inthanethi nganoma yisiphi isikhathi nanoma kuphi.
Ikhaya elihlakaniphile: Ezinhlelweni zasekhaya ezihlakaniphile, ezinjengokhiye beminyango ehlakaniphile, izilawuli zokukhanyisa ezihlakaniphile, izinto zikagesi zasekhaya ezihlakaniphile, njll., isilawuli kude nokuphathwa okuhlakaniphile kungafinyelelwa ngobuchwepheshe obungenawaya.
I-inthanethi Yezinto: Ubuchwepheshe befrikhwensi yomsakazo okungenantambo buyingxenye ebalulekile ye-inthanethi Yezinto. Iqaphela ukuxhumana phakathi kwamadivayisi ngamanethiwekhi ezinzwa ezingenantambo futhi ibona ukuqapha okuhlakaniphile, ukuqoqwa kwedatha nokulawula kude.
Inethiwekhi yenzwa engenantambo: Kumanethiwekhi wezinzwa ezingenantambo, isetshenziswa kakhulu ekuqaphelweni kwemvelo, ezempilo yezokwelashwa, ekulawuleni izimboni kanye neminye imikhakha ukuze kuzuzwe ukuqoqwa kwedatha nokuqapha ngesikhathi sangempela.
Imishini yokulawula kude engenantambo: Ubuchwepheshe befrikhwensi yomsakazo okungenantambo busetshenziswa kakhulu kumaphaneli okulawula njengezilawuli kude ze-TV, izilawuli zemoto, nezilawuli zemodeli ukuze kuqedelwe imisebenzi ekude.
Isistimu ye-radar: Umsakazoubuchwepheshe befrikhwensi budlala indima ebalulekile ezinhlelweni ze-radar futhi busetshenziselwa ukutholwa okuhlosiwe, ukulandelela kanye nokuzulazula. Isetshenziswa kabanzi ku-aerospace, meteorology nakweminye imikhakha.
Ukusetshenziswa kobuchwepheshe befrikhwensi yomsakazo okungenazintambo kubanzi kakhulu, kuhlanganisa imikhakha eminingi, njengokuxhumana kweselula, ukuxhumana ngesathelayithi, amasistimu e-radar, izilawuli kude, amanethiwekhi ezinzwa ezingenantambo, njll. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ubuchwepheshe befrikhwensi yomsakazo ongenazintambo buzoqhubeka budlala. indima ebalulekile emikhakheni eyahlukene, ukuletha ukunethezeka okwengeziwe kanye nokusungula izinto ezintsha ezimpilweni nasemisebenzini yabantu.
Ukuze uthole ulwazi olwengeziwe sicela uvakashele:
