Ko te nuinga o ngā mowhiti paheke mā roto i te kōhao e whakamahi ana i te hononga waku hei hononga hiko. He haumaru, he pono, ā, ka taea te whakatutuki i te maha o ngā hongere e hiahiatia ana e ngā kiritaki. Ko ngā mowhiti paheke kei te mākete i tēnei wā e whakamahi ana i tēnei puka whakapā. Ko ētahi atu ko te whakapā mercury, te tuku infrared, te tuku ahokore, me ētahi atu, ehara nei i te hua matua i tēnei wā, nā te mea he maha tonu ngā herenga o ngā mowhiti paheke kōpae i hangaia i tēnei ara, pērā i te raru o te turuturu o te whakapā mercury, ā, he uaua ki te hanga i te neke atu i te 8 hongere, ā, he tino teitei te utu whakaputa. He raruraru tohu te tuku infrared me ngā tikanga tuku ahokore, ā, kāore e taea te tuku i ngā hongere hiko au-teitei i tēnei ara.
Ka taea te wehewehe i ngā huihuinga mowhiti paheke ki ngā mowhiti paheke auau-iti, ngā mowhiti paheke auau-waenga, me ngā inihi hurihuri auau-teitei e ai ki te auau o te tohu tuku. Ko ngā mowhiti paheke e pā ana ki ngā momo tuatahi e rua anake. Ko ngā tohu mahi hiko o ngā huihuinga mowhiti paheke ko: te ātete whakamahana, te ātete whakapā, te kaha dielectric me te whakawhitiwhiti kōrero. Mō ngā mowhiti paheke auau-waenga, nā te mea he teitei te auau, me whai whakaaro hoki ki te parepare, te taurite aukati, te ngaohiko haruru, me ētahi atu. Mō te hoahoa hanganga, me whakarite tuatahi te whakapā pono kia hono tonu ai ngā raina katoa. Nō reira, me pai te kawe hiko o te rauemi e whakamahia ana mō te paraihe, me tika te pēhanga i runga i te mowhiti paheke, me iti te rerekētanga me te rūrū o te mowhiti paheke, me pai te ātete kakahu, me iti te taipana waku, ā, me ngāwari ki te tiaki.
1) Mowhiti paheke auau-iti: he huihuinga mowhiti paheke e whakamahi ana i te paheke hei tuku tohu auau-iti me te kaha. Ko ngā mowhiti paheke noa ko ngā mowhiti paheke porotaka me ngā mowhiti paheke rerekētanga. Ka wehea ngā mowhiti kawe o ngā mowhiti paheke porotaka ki ngā mowhiti papatahi me ngā mowhiti āhua-V. Ko ngā rauemi o ngā mowhiti kawe he parahi, he parahi, he hiriwa moni me te koura. Ko ngā paraihe he palladium, he koranu koura, he paraihe waea whakakikoruatia koura rānei, me ngā paraihe whakakotahi parahi-graphite. Mena he nui te maha o ngā mowhiti paheke, ko te mowhiti paheke porotaka he huinga e rua o ngā paraihe o runga me raro me te urutau rerekētanga, engari he nui tōna rahi tuaka. Mā te whakamahi i ngā mowhiti paheke rerekētanga ka taea te whakaiti nui i te rahi tuaka, te rōrahi me te taumaha. Ko te mowhiti paheke rerekētanga he huinga e rua o ngā paraihe o runga me raro me te urutau rerekētanga. Ka huri te paraihe o runga me te azimuth o te pūihi, ko te paraihe o raro he mea pumau. E rua ngā huinga o ngā wahi paheke o runga me raro i runga i te pereti urutau rerekētanga. Ka honoa ngā wahi paheke e rite ana e ngā waea, ā, ka whakamahia te tikanga rerekētanga hei hanga i tōna tere hurihanga kia 1/2 o te tere hurihanga azimuth. Ina huri te pūihi, ka rere te iahiko e rere ana ki roto i ia paraihe o raro mā roto i tētahi, i ētahi rānei ara iahiko wāhanga whakapā i runga i te tēpu hurihuri rerekē, ā, ka rere atu i te paraihe o runga e rite ana, kia mau tonu ai te hononga o te ara iahiko i waenga i te wāhanga pūmau me te wāhanga hurihuri. Tērā pea ka puta he ara iahiko poto i waenga i ngā mowhiti nā te paura i mau i te mowhiti pahekeheke whakapā. Nō reira, me whakarite te hanganga kia ngāwari te horoi, ā, ko te tikanga he hanganga whakakotahi hei whakahaere i te whakatikatika, i te whakakapinga rānei o ngā wāhanga i te wāhi.
2) Mowhiti paheke auau waenga: he huihuinga mowhiti paheke e whakamahia ana hei tuku tohu me te kaha o te radar auau waenga (tekau megahertz). He nui ake te auau o tēnei mowhiti paheke, ā, me ārai. Ka taea hoki te whakamahi i ngā mowhiti paheke tere-teitei noa hei tuku tohu i raro i te 12MHz. Ka honoa tētahi mowhiti ki te kaiārahi pokapū, ā, ka honoa tētahi atu mowhiti ki te paparanga o waho o te taura hei mowhiti ārai. Ko ngā mowhiti paheke ārai-rua e whakamahia ana hei tuku tohu i runga ake i te 12MHz. Ko te āhua o te whakawhiti o tēnei mowhiti paheke he awaawa, he rite tonu ki te kaiārahi rua tapawhā. He mowhiti paheke auau waenga kaha hoki, he porowhita te kaiārahi pokapū, e tautokona ana e te papa whakamahana i roto i te paparanga ārai, he āputa i waenganui i te wāhanga hurihuri me te wāhanga pumau, ā, kāore e pā tetahi ki tetahi, ā, ka honoa te tohu auau waenga mā te kaha. Mēnā he iti te whānuitanga o te hurihanga pūihi, ka taea te whakamahi i tētahi taputapu takai taura hei utu mō te mowhiti paheke.
