Sehlopha sa Q-band le EHF (Extremely High Frequency) ke lihlopha tsa bohlokoa tsa maqhubu a maqhubu a motlakase, a nang le litšobotsi tse ikhethang le lisebelisoa tse pharaletseng.
Q-band:
Q-band hangata e bolela sebaka sa maqhubu a pakeng tsa 33 le 50 GHz, se fumanehang sebakeng sa EHF.
Likarolo tsa eona tsa mantlha li kenyelletsa:
Maqhubu a phahameng: bolelele bo bokhutšoane, bo ka bang 6 ho isa ho 9 mm.
High bandwidth: e loketse phetiso ea data e potlakileng.
Libaka tse ka sehloohong tsa ts'ebeliso ea Q-band ke:
Puisano ea satellite: e sebelisetsoa ho phahamisa le ho theola litsamaiso tsa sathelaete tse phahameng ka ho fetesisa (HTS) ho fana ka lits'ebeletso tsa Marang-rang tsa Broadband.
Puisano ea Ground microwave: e sebelisetsoa phetisetso ea data ea sebaka se sekhuts'oane, e phahameng haholo.
Radio astronomy/ Ketso ya seea-le-moea: e sebedisoang ho bona metswedi ya radio e maqhubu a phahameng bokahohleng.
Radar ea likoloi: radar ea nako e khuts'oane e sebelisoang lits'ebetsong tse tsoetseng pele tsa lithuso tsa bakhanni (ADAS).
Sehlopha sa EHF:
Sehlopha sa EHF se bua ka sekhahla sa maqhubu lipakeng tsa 30 le 300 GHz, 'me leqhubu ke 1 ho isa ho 10 mm, kahoo se boetse se bitsoa millimeter wave wave.
Likarolo tsa eona tsa mantlha li kenyelletsa:
Ultra-high frequency: e khona ho fana ka litefiso tse phahameng haholo tsa phetisetso ea data.
Narrow beam: boholo bo nyane ba antenna le ho otloloha ho matla.
Libaka tse kholo tsa ts'ebeliso ea sehlopha sa EHF ke:
Lipuisano tsa sesole: tse sebelisetsoang litsamaiso tsa likhokahano tse nang le litlhoko tse phahameng tsa lekunutu, joalo ka sesole sa US sa Milstar le Advanced Extremely High Frequency (AEHF) sistimi.
Khokahano ea satellite: ho fana ka lits'ebeletso tsa Broadband le ho ts'ehetsa phetiso ea data ka lebelo le holimo.
Sistimi ea radar: e sebelisetsoang liradara tsa litšoantšo tse nang le qeto e phahameng le liradara tsa taolo ea mollo.
Patlisiso ea mahlale: e sebelisetsoa ho lemoha sepakapaka le tlhahlobo ea linaleli tsa seea-le-moea.
Mathata le tsoelopele:
Leha lihlopha tsa Q-band le EHF li na le tebello e pharalletseng ea ts'ebeliso, li ntse li tobana le mathata ts'ebetsong e sebetsang:
Atmospheric attenuation: matshwao a maqhubu a hodimo a ka hlaselwa habonolo ke maemo a boemo ba leholimo a kang ho fokotsa pula nakong ea phatlalatso, e leng se bakang phokotso ea matšoao.
Ho rarahana ha tekheniki: lisebelisoa tse phahameng haholo li na le moralo o phahameng le litlhoko tsa tlhahiso le litšenyehelo tse phahameng.
Ho sebetsana le liphephetso tsena, bafuputsi ba nts'etsapele mekhoa e tsoetseng pele ea ho feto-fetoha le maemo le mahlale a likhoutu, hammoho le maano a bohlale a liheke tse fapaneng ho ntlafatsa ts'epo ea sistimi le bokhoni ba ho thibela tšitiso.
Qetello:
Q-band le EHF-band li phetha karolo ea bohlokoa lipuisanong tsa morao-rao, radar le lipatlisiso tsa saense.
Ka tsoelopele ea theknoloji, ts'ebeliso ea lihlopha tsena tsa maqhubu e tla atolosoa le ho feta, e fane ka menyetla e mecha bakeng sa nts'etsopele ea mafapha a fapaneng.
