Li-resistors tsa RF: lits'ebetso lits'ebetsong tsa radar

Li-resistor tsa RF li bapala karolo ea bohlokoa lits'ebetsong tse fapaneng tsa elektroniki, litsamaiso tsa radar ke e 'ngoe ea tsona. Radar, e khutsufalitsoeng bakeng sa Radio Detection and Ranging, ke theknoloji e sebelisang maqhubu a seea-le-moea ho lemoha le ho fumana lintho tse haufi. E na le mefuta e mengata ea lits'ebetso, ho kenyeletsoa le tlhokomelo ea sesole, taolo ea sephethephethe sa moea, bolepi ba leholimo le litsamaiso tsa ho tsamaea. Sengoloa sena se tla tšohla kamoo li-resistor tsa RF li kenyang letsoho ts'ebetsong le ts'ebetsong ea sistimi ea radar.

Litsamaisong tsa radar, morero o ka sehloohong oa li-resistors tsa RF ke ho khona ho mamella maemo a phahameng a matla le ho fana ka ho bapisa ho nepahetseng ha impedance. Li-resistors tsena li etselitsoe ho qhala mocheso ka katleho, ho netefatsa ts'epo ea sistimi le bophelo bo bolelele. Li sebelisoa likarolong tse fapaneng tsa litsamaiso tsa radar, ho kenyeletsoa li-receiver, li-transmitter le li-antenna.

Tšebeliso ea bohlokoa ea li-resistors tsa RF litsamaisong tsa radar e lipotolohong tsa moamoheli. Li-receiver tsa radar li ikarabella bakeng sa ho hapa le ho sebetsana le matšoao a bonahatsoang ho tsoa linthong tse sebakeng se potolohileng. Li-resistors tsa RF potolohong ea moamoheli li thusa ho boloka botsitso ba ketane ea matšoao le ho fokotsa tahlehelo. Li thusa ho fihlela maemo a hlokahalang a ho fumana le ho utloa bohloko ha li ntse li netefatsa ts'ebetso e tlase ea lerata.

Li-resistor tsa RF le tsona ke karolo ea bohlokoa ea karolo ea phetisetso ea litsamaiso tsa radar. Sefetisetso se hlahisa li-pulse tsa maqhubu a radio tse matla a phahameng tse thunngoang sebakeng. Li-pulse tsena lia tlola nthong ebe li khutlela radar e le li-echo. Li-resistor tsa RF li sebelisoa lipotolohong tsa phetisetso ho sebetsana le maemo a matla a phahameng le ho fana ka tšireletso khahlanong le ho phahama ha motlakase le ho phahama ha motlakase. Li boetse li thusa ho boloka botsitso ba matla a tlhahiso ea phetisetso.

Ho phaella moo, di-resistors tsa RF di sebediswa ditsamaisong tsa di-antenna tsa radar. Di-antenna di bapala karolo ya bohlokwa ho fetiseng le ho amoheleng maqhubu a motlakase. Di-resistors tsa RF di sebediswa meralong ya di-antenna ho laola impedance le ho e bapisa le mothapo wa phetiso. Ho bapisa hona ha impedance ho netefatsa phetiso e phahameng ka ho fetisisa ya matla pakeng tsa mothapo wa phetiso le antenna, e leng se fellang ka mahlaseli a matla a sebetsang hantle le ho lemoha ka nepo.

Li-resistor tsa RF li bapala karolo ea bohlokoa litsamaisong tsa radar. Litšebeliso tsa tsona li akaretsa likarolo le lipotoloho tse fapaneng, li thusa ho ntlafatsa ts'ebetso ka kakaretso, ts'ebetso le ts'epo ea sistimi. Ka ho fana ka ho bapisa impedance ka nepo, ts'ebetso e sebetsang hantle ea matla le ts'ireletso ea ho phahama, li-resistor tsa RF li nolofalletsa litsamaiso tsa radar ho lemoha le ho fumana lintho ka katleho, e leng se etsang hore e be karolo ea bohlokoa ea tšimo ea theknoloji ea radar.
