Whakautu tere:Ko te pūihi ā-wā takiuru he pūihi ahunga whānui i hangaia mai i tētahi raupapa o ngā huānga irahiko tauine. Ka huri ngā rōpū huānga rerekē ki te hiko i ngā auau rerekē, ka taea ai e tētahi pūihi te pupuri i ngā āhuatanga ārai me te irahiko whai hua puta noa i tētahi whānuitanga mahi. E whakamahia whānuitia ana ngā pūihi ā-wā takiuru mō te whakamātautau EMI/EMC, te aroturuki i te whānuitanga, te ine pūihi, te kimi ahunga me ngā pūnaha RF whānui.
He aha te Pūihi Pūmau Log?
A pūihi ā-wā takiuru, e whakarāpopototia ana ko LPA, he whānau pūihi kore-auau e rerekē ana te āhua i roto i te tauira logarithmic e whakahokia ana. Ko te āhua tino noa ko te log periodic dipole array (LPDA), e whakamahi ana i ngā huānga dipole o ngā roa me ngā mokowā rerekē haere i te taha o te pūma tautoko.
He rerekē tēnei i te pūihi whaiti kua hangaia mō te roanga oro matua kotahi, ka whakamahia e te LPDA ētahi huānga tauine hei kapi i ngā roopu auau kua tohua. I tētahi auau mahi, ko te rōpū huānga e tata ana ki te oro anake te mea tino kaha ki te irahiko. Ka kiia tēnei rohe ko terohe hohe. I te hurihanga o te auau, ka neke te rohe hohe i te taha o te rarangi.
He pēhea te mahi a te pūihi ā-wā o te Log?
Ko ngā ine o ngā huānga tata e pā ana ki tētahi tauine tauine, e tohuhia ana e te reta Kariki ko te tau. Ka whai te roa o te huānga, te mokowā me ētahi atu ine i tēnei whanaungatanga ōwehenga. Nā te mea ka tāruarua te hanganga hiko ina huri te auau mā te ōwehenga ōrite, ka taea e te aukati whakauru me te whanonga irahiko te noho pumau i runga i te whānuitanga whānui.
Ko ngā huānga roa rawa e tautoko ana i te wāhanga auau-iti o te awhe whakahaere, ko ngā huānga poto rawa e tautoko ana i te wāhanga auau-teitei. Ka whakawhitihia te pūngao mā roto i tētahi whakaritenga whāngai taurite, ā, ko te whanaungatanga ā-wāhanga i waenga i ngā huānga tata ka puta he hihi ahunga. Ko te whakanui tuturu, te whānui hihi, te ōwehenga mua-ki-muri me te taurite ārai e whakawhirinaki ana ki te āhuahanga taipitopito, te hanganga tautoko, te taiao whāngai me te tāutanga.
Ngā Āhuatanga Matua o te Mahi
- Whānuitanga whakahaere whānui:Ka taea e tētahi tauira te kapi i tētahi awhe whānui ake i tētahi dipole resonant tuku iho, ka whakaiti i te hiahia ki te whakawhiti pūihi i ngā wā ine auau swept-frequency.
- Te irahiko aronga:Ka āwhina te hihi matua ki te whakapai ake i te whiriwhiri ā-wāhi mō ngā mahi aroturuki, ine me te kimi ahunga.
- Whēkenga pumau:Ka taea e tētahi huinga i hangaia tika te whakarato i te whai huatanga o te whakanui me te aukati puta noa i tōna awhe kua tohua, ahakoa me tirohia ia tawhā i runga i te pepa raraunga takitahi.
- Te pōraitanga rārangi-rua, rārangi-rua rānei:Kei te tauira te whakapolarisasi. Ka taea e ngā hoahoa whakapolarisasi-rua te tautoko i ngā whakapolarisasi raina orthogonal e rua i roto i te huihuinga pūihi kotahi.
- Tauwhitinga rahi-auau:Ko te hipoki auau iti e hiahia ana ki ngā wāhanga roa ake me te hanganga miihini nui ake. Nō reira, he mea nui ngā here o te wāhi whakairi, te uta hau me te tawhiti whakamātautau i te wā e tīpakohia ana.
Ngā tono noa
- Ngā whakamātautau EMI me te EMC:ngā inenga tukunga hihi whānui me te ārai mate puta noa i ngā awhe auau kua tohua.
- Te ine i te pūihi:te whakatairite i te whiwhinga, te ine i te tauira-ira me te mahi awhe whakamātautau whānui.
- Te aroturuki i te whānuitanga:te whiwhi tohu i runga i ngā roopu auau maha me te kore e whakakapi i te pūihi i ngā wā katoa.
- Te kimi ahunga me te tirotiro:Ka tautoko te urupare aronga i te tātari tohu-whai ina whakauruhia ki roto i tētahi pūnaha RF e tika ana.
- Rangahau Ahokore me te RF:te tuku, te whiwhi rānei mō te kaupapa whānui i roto i ngā taiwhanga ine me ngā wāhi ine parae.
Me pēhea te whiriwhiri i tētahi pūihi ā-wā o te rangitaki
Tīmata ki te ine katoa, ki te whakaritenga pūnaha rānei, kaua ki te whānuitanga auau anake. Mā ēnei kōrero e āwhina ngā kaihangarau me ngā kaihoko ki te whakataurite i ngā tauira:
| Tauwehenga kōwhiringa | He aha te hiranga |
