I-Q-band kunye ne-EHF-band: Isicelo kunye nethemba lobuchwepheshe be-high-frequency technology

I-Q-band kunye ne-EHF (i-Frequency ephezulu kakhulu) ibhendi ebalulekileyo yefrikhwensi kwi-spectrum ye-electromagnetic, eneempawu ezizodwa kunye nokusetyenziswa okubanzi.

Q-band:

I-Q-band idla ngokubhekisa kuluhlu lwamaza phakathi kwe-33 kunye ne-50 GHz, efumaneka kuluhlu lwe-EHF.

Iimpawu zayo eziphambili ziquka:

Ukuphindaphinda okuphezulu: ubude obufutshane, malunga ne-6 ukuya kwi-9 mm.

I-bandwidth ephezulu: ilungele ukuhanjiswa kwedatha ngesantya esiphezulu.

Ezona ndawo zisetyenziswayo zeQ-band zezi:

Unxibelelwano ngesathelayithi: isetyenziselwa ukunyuswa kunye nokuthotywa kwe-high-throughput satellite (HTS) iinkqubo zokubonelela ngeenkonzo ze-Intanethi ezibanzi.

Unxibelelwano lwe-microwave ephantsi: isetyenziselwa ukuhanjiswa kwedatha kumgama omfutshane, umthamo ophezulu.

I-astronomy yerediyo: isetyenziselwa ukujonga imithombo yerediyo yefrikhwensi ephezulu kwindalo iphela.

I-radar ye-Automotive: i-radar yoluhlu olufutshane olusetyenziswa kwiinkqubo zokuncedisa umqhubi ophezulu (ADAS).

Ibhendi ye-EHF:

Ibhendi ye-EHF ibhekisa kuluhlu lwamaza phakathi kwe-30 kunye ne-300 GHz kwaye ubude be-waveleng yi-1 ukuya kwi-10 mm, ngoko ikwabizwa ngokuba yi-millimeter wave band.

Iimpawu zayo eziphambili ziquka:

I-Frequency ephezulu kakhulu: ekwaziyo ukubonelela ngamazinga aphezulu kakhulu othumelo lwedatha.

Umqadi omxinwa: Ubungakanani be-eriyali encinci ngokwentelekiso kunye nokwalatha okuqinileyo.

Ezona ndawo zisetyenziswayo ze-EHF band zezi:

Unxibelelwano lwasemkhosini: lusetyenziselwa iinkqubo zonxibelelwano ezineemfuno eziphezulu zemfihlo, ezifana neenkqubo zomkhosi wase-US i-Milstar kunye ne-Advanced Extremely High Frequency (AEHF).

Unxibelelwano lweSathelayithi: ukubonelela ngeenkonzo zebroadband kunye nokuxhasa ukuhanjiswa kwedatha ngesantya esiphezulu.

Iinkqubo zeRadar: ezisetyenziselwa i-radars ye-high-resolution imaging radars kunye neeradar zokulawula umlilo.

Uphando lwezeNzululwazi: lusetyenziselwa ukubonwa kwe-atmospheric kunye ne-radio astronomy observations.

Imingeni kunye nophuhliso:

Nangona iibhendi ze-Q kunye ne-EHF zinamathuba abanzi okusebenza, zisajongene nemingeni ethile kwizicelo ezisebenzayo:

Ukuthotywa kwe-atmospheric: imiqondiso ye-frequency ephezulu ichaphazeleka kwimiba yemozulu efana nokuthomalalisa imvula ngexesha losasazo, okukhokelela ekuthotyweni komqondiso.

Ubunzima bobugcisa: izixhobo eziphezulu ze-frequency zinoyilo oluphezulu kunye neemfuno zokuvelisa kunye neendleko eziphezulu.

Ukuhlangabezana nale mingeni, abaphandi baphuhlisa itekhnoloji yokumodareyitha ephezulu kunye neekhowudi, kunye nezicwangciso ezikrelekrele zokwahlukana kwesango lokuphucula ukuthembeka kwenkqubo kunye namandla okuchasana nokuphazamiseka.

Isiphelo:

I-Q-band kunye ne-EHF-band idlala indima ebalulekileyo kunxibelelwano lwanamhlanje, i-radar kunye nophando lwesayensi.

Ngokuqhubela phambili kwetekhnoloji, ukusetyenziswa kwezi bhendi zefrikhwensi kuya kwandiswa ngakumbi, kubonelele ngamathuba amatsha ophuhliso lweenkalo ezahlukeneyo.
