Ngā Pūnaha Whakawhitiwhiti Kōrero i raro i te Wai: Ngā Auahatanga me ngā Wero
Kua noho ngā pūnaha whakawhitiwhiti kōrero o raro i te wai hei wāhanga hangarau e pārekareka ana ki ngā kaipūtaiao me ngā miihini o te ao katoa. He maha ngā mea ngaro kāore anō kia whakatauhia i roto i ngā moana, e kapi ana i te 71% o te mata o te Ao. Heoi, ko ngā taunekeneke me ngā rangahau e pā ana ki te ora i raro i te wai, te tūhuratanga o ngā kohuke, me te haumarutanga moana, e tino whakawhirinaki ana ki ngā pūnaha whakawhitiwhiti kōrero whai hua i roto i te taiao i raro i te wai.
He aha te hiranga o te whakawhitiwhiti kōrero i raro i te wai?
He mea nui te mahi whakawhitiwhiti kōrero i raro i te wai i roto i ngā momo mahi maha, tae atu ki ngā rangahau moana, te aroturuki taiao, te tūhuratanga hinu me te hau, ngā mahi hōia, me te pūtaiao moana. Ahakoa ngā mahi o ia rā pēnei i te ruku me ngā hākinakina wai, me whai pūnaha whakawhitiwhiti kōrero pono. Ki te kore he whakawhitiwhiti kōrero whai hua, ka raru pea ēnei mahi i ngā herenga me ngā mōrearea nui.
He mea nui anō hoki te whakawhitiwhiti kōrero i raro i te wai hei pupuri i te haumaru o raro i te wai me te ārai i ngā āhuatanga kino. Hei tauira, e whakamahia ana tēnei hangarau mō te kimi wawe i ngā tsunami, te aroturuki i te parahanga moana, me ngā rangahau aituā o raro i te wai.
Ngā Mātāpono Taketake o te Whakawhitiwhiti Kōrero i raro i te Wai
He rerekē ki te whakawhitiwhiti kōrero ā-rangi, e whakamahi ana i ngā ngaru reo irirangi, ko te whakawhitiwhiti kōrero ā-wai he nui ake te whakawhirinaki ki ngā ngaru oro. Ka tere te pirau o ngā ngaru reo irirangi i roto i te wai, ā, kāore e taea te whakawhitiwhiti kōrero tawhiti i raro i te wai. I tētahi atu taha, ka taea e ngā ngaru oro te haere tawhiti atu, ahakoa he puhoi ake i te tere i te rangi.
Ka whakamahia ngā ngaru oro i ngā auau rerekē i runga i ngā hiahia whakawhitiwhiti kōrero. Ka taea e ngā auau iti te haere i ngā tawhiti roa engari he iti ake ngā tere whakawhiti raraunga, ko ngā auau teitei ia e whakamahia ana mō te whakawhitiwhiti kōrero poto engari he teitei ngā tere whakawhiti raraunga.
Hangarau me ngā Tikanga
1. Te Whakarerekētanga Oro
– Ko te Whakarerekētanga Auautanga (FM) me te Whakarerekētanga Amplitude (AM) he tikanga whakarerekētanga e rua e whakamahia ana i roto i ngā whakawhitiwhiti kōrero i raro i te wai. Ka whakamahia e ēnei whakarerekētanga ngā huringa o te auau, te amplitude rānei hei whakawaehere i ngā mōhiohio.
– Kei te piki haere te rongonui o te Phase-Shift Keying (PSK) me te Frequency-Shift Keying (FSK) nā te mea he pai te whakahaere i ngā raraunga kikī.
2. Ngā Pouwhanga Oro
– He rite ki ngā pouwhanga i roto i ngā whakawhitiwhitinga matihiko, ka hurihia e ngā pouwhanga oro ngā raraunga matihiko hei tohu oro, ā, ka hurihia hoki. Ka taea te tāuta i ēnei pouwhanga ki runga i ngā waka ruku, ngā pūoko raro wai, ngā taputapu ruku rānei hei tuku me te whiwhi mōhiohio.
3. Whakawhitiwhiti Kōrero Whatu
– Ahakoa he iti ake te rongonui i te whakawhitiwhiti kōrero oro, he tere teitei te whakawhitiwhiti kōrero whatu (mārama) engari mō ngā tawhiti iti ake. Ka taea te whakamahi i tēnei hangarau mō te whakawhitiwhiti kōrero poto me te whānui o te whānui.
4. Ngā Pūnaha Ranu
– Ka whakakotahi ngā pūnaha ranu i ngā tikanga oro me ngā tikanga whatu hei whakanui ake i te whai huatanga o ngā whakawhitiwhiti kōrero i raro i te wai. E tūmanakohia ana ka whakakotahi ēnei pūnaha i ngā painga o ia huarahi hei wikitoria i ō rātou herenga.
Ngā Wero i roto i te Whakawhitiwhiti Kōrero i raro i te Wai
He maha ngā wero motuhake e pā ana ki te urutau i te hangarau whakawhitiwhiti kōrero ki ngā taiao o raro i te wai, tae atu ki:
1. He Taiao Hurihuri, Hihiri hoki
– He rerekē rawa te tere o te oro i roto i te wai i runga i te pāmahana, te hohonutanga, me te tote. Ka rerekē pea te wā horapa me te whakapōturitanga o te tohu i tēnei.
2. Te Whakawhanuitanga o te Ara Maha
– Ka taea te whakaata i ngā ngaru oro e tukuna ana e ngā mea o raro i te wai, pērā i te mata o te moana, te papa moana, me ētahi atu mea. Ka taea e tēnei te whakararuraru nui i te tohu me te whakararuraru.
3. Haruru
– Ka pāngia te kounga o te tohu e te haruru taiao (pērā i ngā ngaru o te moana, ngā mahi koiora o te moana), me ngā mahi a te tangata (pērā i ngā haruru o ngā kaipuke, ngā mahi ahumahi rānei huri noa i te moana).
4. Ngā Here Pūngao
– Ko ngā taputapu raro i te wai, pērā i ngā pūoko, ngā pouwhanga oro rānei, he iti noa te kaha e pau ana. Me hangaia kia penapena pūngao kia tu atu ai i te whakamahinga roa me te kore e hiahiatia he tiaki auau.
5. Ngā Herenga o te Whānuitanga Ipurangi
– Ko ngā auau iti e taea te haere tawhiti te kawe raraunga i ngā tere iti, ka hanga he raruraru i waenga i te awhe me te tere whakawhiti raraunga.
