Te awhe auau i roto i te Radio, a Pouaka Whakaata

Range Auautanga - he wā e whānui i whakamahia i roto i te akoranga o ngā kaupapa hangarau tinana, i roto i ngā i roto i te hikohiko. I raro i tenei ariā e matau reira rite te whānuitanga whakahaere o te pūrere, me te ratonga reo irirangi i whakatapua hoki pāpāho i te ngā tūmomo auau. A ka taea e tatou e te kōrero e pā ana ki te rärangi o te awhe auau irirangi katoa.

ture International tino whakahaere te whakamahi o rerekē pūnaha haapurororaa irirangi (tae atu amiorangi), i te whānuitanga pai-tautuhi. fakahā tenei e te hiahia ki te whakarite mahitahi o ngā pūnaha rerekē, me te mahi ki te whakakore raweketia.

E ai ki nga Rekureihana Radio, e tahuri iho te rohe o te whenua ki toru rohe nui. Kei roto te tuatahi Europe, Kihi, Russia, Mongolia ko Africa. Ko te tuarua - te rohe o Amerika (e rua Te Tai Tokerau me Tonga). Tuatoru - Tonga me te rohe Kiwa Tonga-Te Tai Rāwhiti Asia, Ahitereiria,. I roto i ia rohe - tona tohatoha o here auau irirangi.

Hoki te mahi o te ture amiorangi kōrero whakarato here auau ki ngā tohu: L, awhe S, C, X, Ku, Ka, K i 1452 MHz ki 86,0 GHz. Ko te nuinga o ngā pūnaha amiorangi mahi i roto i here C me Ku. kaha Range Ka whakawhanakehia i roto i Europa ko Amerika, engari i roto i to tatou whenua e kore e whakamahia whānuitia.

Ko ti'aturi i runga i te maha o nga wavelengths e uru te diameter o te pūihi te tōtika pūihi. Ki te whakanui ake i te auau, te roangaru kua heke (e inversely hautanga enei uara) me kore te te pūihi nui e hiahiatia ana ki te farii i tohu auau tiketike. Mai te awhe auau riro e te rahi pūihi o 2.5-4.5 mita, me mo te fariiraa i te ropu poipoi e hiahiatia K rahi pūihi -. 10-15 anake cm Ki te Antennas rahi taua mahi i roto i te whānuitanga tiketike, whai taonga teitei.

I roto i ia teihana tuku pāpāho hoki kua tona whānuitanga auau. He he he whakarōpū o ngaru irirangi i runga i te whānuitanga me te roangaru. E ai ki tenei ngaru e:

- Dekametricheskie ki te roangaru o te tikanga o te 10 000-100 000 kiromita, Whakaröpütia rite tino iti nei iarere (3 - 30 Hz).

- Megametricheskie (roangaru - 000 kiromita 1000-10), te whānuitanga auau - 300 Hz.

- Gektokilometrovye (ki te roa o 100-1,000 kiromita) e pā ana ki te auautanga ultralow (3000 Hz).

- tāpiri roa (roa - 10-100 kiromita) - te tino iti (ki runga, ki te 30 kHz).

- roa (roa o 1-10 kiromita) - iti (ki runga ki te 300 kHz).

- Toharite (roa 100-1000 mita) - mids ki 3000 kHz.

- Poto, he roa o 10-100 mita - he mea te-ka karanga kia .. auau teitei (auau 30 MHz).

- Ultrashort mita (te roa 1-10 mita), tiketike rawa (ki runga, ki te 300 MHz) ranei.

- Decimeter (roa 10-100 cm) me ultra-tiketike, ki runga ki te 3000 MHz.

- henemita (1-10 henimita te roa), super-tiketike (ki runga, ki te 30 GHz).

- mirimita (roa 1-10 mm), tiketike rawa (ki runga, ki te 300 GH).

E pā ana 300-3000 ngā GHz auau ki te t. n. Kōnei-tiketike ngā auau.

I roto i te wāhanga tuatahi o te whanaketanga o te ngaru irirangi whakamahia te nuinga roa me te super-roa ngā. Ko e horahanga ratou i runga i te mata o te whenua, kei te kaha whenumi, e hiahiatia ana ongoi e kaha. kawea fariiraa pūmau i roto i runga i ngaru reo, engari ki a ratou he reira uaua ki te whakarite i te tawhiti tuku, ka whakamahi i tenei whānui, te nuinga irirangi rohe ki te pūtoro o te maha rau kiromita.

whakarato ngaru whānui nui, engari he ngohengohe ki te haruru me te tohu distortion. E whakamahia te nuinga ratou i roto i te rangi, me te moana whakatere, ka hono ki te rārangi matua.

Ko te painga matua o nga awhe tiketike-auau - taea ki te whakamahi i pūihi, he whai hua te radiation anake i raro i tenei huru e rite ki te roangaru nei āhuatanga. Construction o ngā pūnaha whakawhiti kōrero roa-tawhiti e hāngai ana i runga i te whakatö o ngaru i titiro, i hanga taea ki te whakamahi o horihori āmiorangi whenua.
