Ibhendi ye-Q kanye nebhendi ye-EHF: Ukusetshenziswa kanye namathemba obuchwepheshe obusebenzisa imvamisa ephezulu

Ibhendi ye-Q kanye nebhendi ye-EHF (Extremely High Frequency) ziyibhendi zemvamisa ezibalulekile ku-spectrum ye-electromagnetic, ezinezici ezihlukile kanye nezinhlelo zokusebenza ezibanzi.

Ibhendi ye-Q:

I-Q-band ivame ukubhekisela kububanzi bemvamisa obuphakathi kuka-33 no-50 GHz, obutholakala kububanzi be-EHF.

Izici zayo eziyinhloko zifaka:

Imvamisa ephezulu: ubude be-wavelength obufushane, cishe buyi-6 kuya ku-9 mm.

I-bandwidth ephezulu: ilungele ukudluliswa kwedatha ngesivinini esikhulu.

Izindawo eziyinhloko zokusetshenziswa kwe-Q-band yilezi:

Ukuxhumana ngesathelayithi: okusetshenziselwa ukuxhumanisa nokwehlisa izinhlelo zesathelayithi ezisebenzisa i-high-throughput (HTS) ukuze kuhlinzekwe ngezinsizakalo ze-inthanethi ezibanzi.

Ukuxhumana nge-microwave ephansi: okusetshenziselwa ukudlulisa idatha ibanga elifushane, elinamandla aphezulu.

Isayensi yezinkanyezi yomsakazo: isetshenziselwa ukubona imithombo yomsakazo evame kakhulu endaweni yonke.

I-radar yezimoto: i-radar yebanga elifushane esetshenziswa ezinhlelweni zokusiza abashayeli ezithuthukisiwe (i-ADAS).

Ibhendi ye-EHF:

Ibhendi ye-EHF ibhekisela kububanzi bemvamisa ephakathi kuka-30 no-300 GHz kanti ubude be-wavelength bungu-1 kuya ku-10 mm, ngakho-ke ibizwa nangokuthi ibhendi yamagagasi e-millimeter.

Izici zayo eziyinhloko zifaka:

Imvamisa ephezulu kakhulu: ekwazi ukunikeza amazinga aphezulu kakhulu okudlulisa idatha.

Umsebe omncane: usayizi omncane we-antenna kanye nesiqondiso esiqinile.

Izindawo eziyinhloko zokusetshenziswa kwebhendi ye-EHF yilezi:

Ukuxhumana kwezempi: okusetshenziselwa izinhlelo zokuxhumana ezinezidingo eziphezulu zobumfihlo, njengezinhlelo ze-Milstar kanye ne-Advanced Extremely High Frequency (AEHF) zamasosha ase-US.

Ukuxhumana ngesathelayithi: ukuhlinzeka ngezinsizakalo ze-broadband nokusekela ukudluliswa kwedatha okusheshayo.

Izinhlelo ze-radar: ezisetshenziselwa ama-radar okuthwebula izithombe anesinqumo esiphezulu kanye nama-radar okulawula umlilo.

Ucwaningo lwesayensi: olusetshenziselwa ukuthola umkhathi kanye nokubuka izinkanyezi ngomsakazo.

Izinselele kanye nentuthuko:

Nakuba amabhendi e-Q-band kanye ne-EHF enamathuba amaningi okusetshenziswa, asabhekene nezinselele ezithile ekusetshenzisweni okusebenzayo:

Ukuncipha komoya: izimpawu zemvamisa ephezulu zithinteka yizici zesimo sezulu njengokuncipha kwemvula ngesikhathi sokusabalala, okuholela ekunciphiseni kwesignali.

Ubunzima bobuchwepheshe: amadivayisi asebenza imvamisa ephezulu anezidingo eziphezulu zokuklama nokukhiqiza kanye nezindleko eziphakeme.

Ukuze babhekane nalezi zinselele, abacwaningi bathuthukisa ubuchwepheshe obuthuthukisiwe bokuguqulwa kwesimo kanye nokubhala amakhodi, kanye nezinhlelo ezihlakaniphile zokwehlukahluka kwesango ukuze kuthuthukiswe ukuthembeka kwesistimu kanye namakhono okulwa nokuphazamiseka.

Isiphetho:

I-Q-band kanye ne-EHF-band zidlala indima ebalulekile kwezokuxhumana zanamuhla, ocwaningweni lwe-radar kanye nesayensi.

Ngokuthuthuka kobuchwepheshe, ukusetshenziswa kwala ma-frequency band kuzokwandiswa kakhulu, kuhlinzeke ngamathuba amasha okuthuthukiswa kwemikhakha eyahlukene.
