Imodi Yokusakaza yamagagasi omsakazo
Njengomthwali wokusabalalisa ulwazi kuukuxhumana okungenantambo, amaza omsakazo atholakala yonke indawo ekuphileni kwangempela.Ukusakaza okungenantambo, i-TV engenantambo, ukuxhumana ngesathelayithi,ezokuxhumana ngomakhalekhukhwini, i-radar, ne-wirelessIP MESHAmathuluzi okuxhumana wonke ahlobene nokusetshenziswa kwamagagasi omsakazo.
Indawo yokusabalalisa yamaza omsakazo inkimbinkimbi kakhulu, okuhlanganisa indawo ekhululekile (indawo ekahle engapheli, isotropic wave wave, vacuum noma isikhala esilinganayo esingalahleki esiphakathi nendawo, okuwumbono wesayensi ohlongozwayo ukwenza lula ucwaningo lwenkinga) ukusabalalisa kanye nendawo (uqweqwe lomhlaba, ulwandle). amanzi, umkhathi, njll.) ukusabalalisa.
Futhi amaza omsakazo anezindlela ezihlukahlukene zokusakaza, okuhlanganisa cishe zonke izinqubo zokusakazeka kwamagagasi omsakazo, njenge: imisebe eqondile, i-reflection, i-refraction, i-diffraction, ukusabalalisa, njll.
Imisebe eqondile
Imisebe eqondile yindlela amaza omsakazo ahamba ngayo endaweni ekhululekile.Akukho ukuboniswa, ukuphikiswa, ukuhlakazeka, ukuhlakazeka kanye nokumuncwa kwamaza omsakazo endaweni ekhululekile.
Ukuzindla
Lapho igagasi kazibuthe kagesi lihlangana nento enkulu kakhulu kunobude beza, kwenzeka into yokubonisa (ukushintsha isiqondiso sokusakazeka kusixhumi esibonakalayo phakathi kwemidiya emibili kanye nokubuyela endaweni yokuqala) kwenzeka.
Rukukhishwa
Lapho igagasi kazibuthe lingena kwenye indawo lisuka endaweni eyodwa, indlela yokusakazeka iyashintsha (i-engeli ethile yakheka ngendlela yokuqala, kodwa ayibuyeli endaweni yokuqala).
I-Diffraction
Lapho umzila wokusabalalisa phakathi kweokungenantamboumthumelifuthi umamukeli uvinjwe isithiyo, igagasi lomsakazo liyaqhubeka nokuhamba lizungeze umkhawulo wesithiyo.I-Diffraction yenza amasignali omsakazo asakazwe ngemuva kwezithiyo.
Sukudla
Ngenxa yokungahlangani kwe-propagation medium - njengokugobile okukhulu, ukuhwalala, njll., isenzakalo samagagasi kazibuthe kagesi asakazekela endaweni ezungezile siyabangelwa.Ukusabalalisa kwenzeka uma kunezinto ezincane kunobude beza bendlela yokusabalalisa, futhi inani lezinto ezinjalo ezivimbela umthamo weyunithi likhulu kakhulu.
Endaweni evamile yokuxhumana kwamaselula, ukuxhumana phakathi kwesiteshi sesisekelo samaselula kanye nesiteshi esihambayo akuhambi ngendlela eqondile, kodwa ngezinye izindlela eziningi.Ngesikhathi sokusakazwa kwamagagasi omsakazo, izinto ezihlukene zizohlangana nazo, ngakho-ke ngaphezu kwemisebe eqondile, ukubonakaliswa okuhlukile, ukuphikisana nokuhlakazeka nakho kuzokwenzeka.Lawa masignali afika kumamukeli ngezindlela ezihlukene zokusakaza anama-amplitude ahlukene nezigaba.Umthelela wabo ohlangene uzodala ukuthi isiginali etholwe umamukeli ibe yinkimbinkimbi kakhulu, futhi ibangele ukuphazamiseka noma ukuhlanekezela, okungukuthi, inqwaba.-umphumela wokusabalalisa indlela.
Indlela yokusebenzisa amaza omsakazo kuukuxhumana?
Umgomo wokusebenzisa amaza omsakazo weukudluliswa kwevidiyoukuguqula amasignali evidiyo abe amaza kagesi bese uwadlulisela ngothi.Ngemva kokuthola amaza kagesi kazibuthe, uthi olusemaphethelweni okwamukela luyawaguqula abe amasignali evidiyo asekuqaleni.Ukuxhumana ngomsakazo, ukuxhumana ngomakhalekhukhwini, ukuxhumana ngesathelayithi, njll. konke kwenziwa kusetshenziswa amaza kagesi.Phakathi kwazo, amaza kagesi amaza ahlukene angasetshenziselwa izindlela ezahlukene zokuxhumana.Ngokwesibonelo, amaza omsakazo asetshenziswa kakhulu kwezokusakaza, kumabonakude, nakwezokuxhumana ngomsakazo, kuyilapho ama-microwave esetshenziswa kuma-radar, ezokuxhumana ngesathelayithi, nezokuxhumana ngomakhalekhukhwini, phakathi kwezinye izinto.
Ikomkhulu le-IWAVE nesikhungo se-R&D zitholakala e-Shanghai.Kuyibhizinisi likazwelonke lobuchwepheshe obuphezulu eligxile ekuxazululeni izixazululo zokudlulisa okungenazintambo.Izisebenzi eziyinhloko zenkampani zivela ezinkampanini eziphezulu zokuxhumana zamazwe ngamazwe, zonke ezineminyaka engaphezu kweyi-8 kuya kweyi-15 yesipiliyoni somsebenziukuxhumana okungenantamboamasimu.I-IWAVE izibophezele ekuthuthukiseni nasekuhlinzekeni amasistimu okudlulisa amavidiyo angenantambo anencazelo ephezulu kanye ne-wireless broadbandIP MESHamanethiwekhi.Imikhiqizo yayo inezinzuzo zebanga elide lokudlulisela, i-latency ephansi, ukudluliselwa okuzinzile kwezindawo eziyinkimbinkimbi, futhi isetshenziswe kabanzi kuma-drones, amarobhothi, izimo eziphuthumayo zomlilo, ukuhlolwa, ukuphepha nezinye izinkambu ezikhethekile.
