He aha te Radar PESA? Te āhua o tana mahi, me ngā mea me tirotiro e ngā miihini

Ko te radar PESA, he arai matawai hiko kore mahi, e whakamahi ana i tētahi hoahoa tuku/whiwhi RF pokapū hei whāngai i ngā huānga pūihi maha mā roto i tētahi whatunga tohatoha. Mā ngā nekehanga ā-wāhanga e whakahaeretia ana e te hiko ka whakatakoto i te ā-wāhanga whanaunga ki ngā huānga, nō reira ka hangaia e te hihi whakakotahi he hihi i roto i tētahi ahunga whakahau. Kāore e hiahiatia kia huri ā-mīhini te kōhao katoa mō ia huringa tohu.

Whakautu tere:Ka whakaratohia e te PESA he urungi hiko hiko me te hoahoa RF pokapū. Ko tana mahi tuturu e whakawhirinaki ana ki tetahi mea nui atu i te kupu whakarāpopoto. Me manatoko e ngā kaihangarau te whakanui i te koki matawai, te ngaronga whatunga whāngai, te whānui o te mahi, ngā taha taha, te pōraritanga, te whakatikatika, te huringa mahi, ngā rohe wera me te papa tohutoro ine i mua i te whakatau mena ka tutuki te hoahoa i te tono.

He mea nui tēnei nā te mea ka taea e tētahi whakatakotoranga i inehia i te tirohanga pūngao anake te huna i ngā āhuatanga e whakahaere ana i te mahi mara. Kāore te pikinga teitei e whakaatu i te āhua o te huringa o te hihi tata ki te taha o te wāhanga matawai. Kāore te whānuitanga o te auau mahi e whakaatu ana kei te mau tonu te tohu hihi puta noa i te roopu. Ka whakamāramahia e ngā wāhanga e whai ake nei te mahi a te PESA me ēhea pātai e whakaiti ana i te mōrearea whakauru.

Me pēhea te mahi a te Radar PESA

Ka taea te whakatinana i tētahi hoahoa PESA i ngā huarahi rerekē, engari e rima ngā wāhanga mahi o te ara tohu. Ko ētahi pūnaha e whakamahi ana i ngā ara iti, i ngā hongere tāpiri rānei, nō reira me tirotirohia tonu te hoahoa poraka ki te hoahoa tuturu.

1. Te whakaputa ngaru me te hurihanga RF. Ka hangaia e te kaiwhakaoho te ngaru e hiahiatia ana, ka hurihia ki te auau whakahaere. Kātahi ka whakaarahia e te tuku te tohu ki te taumata mana e hiahiatia ana.
2. Te tohatoha hiko. Ka wehea te tohu tuku e te whatunga whāngai ki waenga i ngā ara maha. Ka whakamahia pea e te whatunga ngā arataki ngaru, ngā raina tuku, ngā wehewehe hiko, ngā hononga me ētahi atu wāhanga ngaruiti.
3. Whakahaere ā-wāhanga. Ka hurihia te ā-wāhanga tohu e te kaitahuri ā-wāhanga i ia ara huānga, i ia ara whāiti rānei, kia rite ki te ahunga hihi kua whakahaua. Mā te haere whakamua o te ā-wāhanga puta noa i te āputa e whakatau te wāhi e puta ai te pokanoa hangahanga.
4. Te hanganga o te hihi me te hihi. Ka hihi ngātahi ngā huānga pūihi. Ka kaha te tāpiri o ō rātou mara ki te ahunga kua tohua, ā, ka whakakorea ētahi wāhanga ki ētahi atu ahunga, ka hangaia he hihi matua me ngā taha taha.
5. Te whakahaere whiwhi me te whakatikatika. Ka hoki ngā tohu whakaata mā te pūaha me te whatunga whāngai ki te mekameka kaiwhiwhi. Ka whakatikahia e ngā raraunga whakatikatika ngā rerekētanga ā-wāhanga me te kaha i puta mai i ngā ātete wāhanga, te pāmahana, te auau me te koroheketanga.

Ka taea e te urungi hiko te neke i te hihi kia tere ake i te neke ā-tinana i tētahi kōhao nui. Heoi, ko te tere matawai whai hua ka whakawhirinaki anō hoki ki te wā ngaru, te whakaroa whakahaere, te tukatuka tohu me te kaiwhakarite rauemi radar. Kāore te tere urungi pūihi anake e whakatau i te maha o ngā ūnga, ngā mahi rānei ka taea e te radar katoa te tautoko.

He aha i huaina ai he huinga matawai hiko kore mahi

Ko te kupu pāhekoheko e whakaahua ana i te hoahoanga RF i te pūaha. I roto i te PESA tikanga, kāore i roto i ngā huānga pūihi he waeine tuku me te whiwhi hohe katoa. Ka tukuna, ka whiwhi hoki te mekameka RF pokapū i te pūngao mā te whatunga whāngai, ko ngā wāhanga whakahaere-wāhanga ia e hanga ana i te hihi. Me whai mana hiko tonu te rarangi mō te whakahaere, te whakawhiti, te whakamatao me ētahi atu mahi.

He rerekē anō hoki te radar PESA i te radar kore mahi. Ko te tikanga, ka kitea e te radar kore mahi ngā whakaata mai i ngā tuku o waho, i ētahi atu whakamārama whai wāhitanga rānei. Ko te PESA he hoahoa pūihi me te tohatoha RF ka taea te whakamahi i roto i te radar tuku kaha. Mā te whakapoauau i ēnei tikanga e rua ka hē ngā whakaritenga pūnaha.

Ko ēhea ngā tawhā e whakatau ana i te mahi a te PESA

Ko te whakatakotoranga tino whai hua ko te matihiko o te mahi i runga i te auau, te koki matawai, te porowhita me te āhua whakahaere. Kei te ripanga i raro nei ngā tūemi me tautuhi i mua i te whakataurite i ngā rarangi, i te tono utu rānei.

He aha i huri ai te mahi me te koki matawai

Ko te nuinga o te wā, ko te arai ā-wāhanga te mea tino kaha rawa atu i te taha o te pūwero, te ahunga noa ki te pūwero. I te mea ka nekehia te hihi ki tawhiti atu, ka iti haere te pūwero kua whakaaturia i te ahunga matawai. Tērā pea ka iti ake te hihi e tukuna ana e te tauira huānga i te koki kua whakahaua. Ka taea e ngā hapa whāngai, te hononga tahi, ngā ātete hanganga me te radome te tāpiri atu i te whakapōturitanga.

Ko te hua ka uru atu ki te ngaronga o te matawai, te whānui o te hihi, ngā taha taha kua nekehia, te whakawhiti-polarization teitei ake, te hapa tohu rānei. Kāore ēnei huringa e hopukina e te uara whakanui boresight kotahi. Mō tētahi rarangi e whakaarohia ana hei matawai ki tētahi koki kua tohua, tonoa te whakanui me ngā raraunga tauira i te boresight, tētahi, neke atu rānei o ngā koki waenga, me te taha o te rāngai e hiahiatia ana. Whakahokia te tirotiro i ngā auau mahi iti rawa, waenga me teitei rawa.

Me aro nui ki te mokowā o ngā huānga. Mēnā he nui rawa te mokowā e pā ana ki te roangaru me te koki matawai, ka taea e ngā porowhita whatu kore e hiahiatia te uru ki te rohe e kitea ana. Tērā pea ka rerekē te whanonga o tētahi hoahoa e whakaaetia ana i te pito o raro o te whitiki i te auau teitei rawa, ina ko te mokowā ā-tinana kotahi e tohu ana i ngā roangaru maha atu.

He aha te pānga o te whānuitanga o te hononga me te tirohanga hihi ki te PESA?

He maha ngā pūnaha PESA e whakamahi ana i ngā nekehanga ā-wāhanga hei waihanga i tētahi ahunga whakamua ā-wāhanga e tika ana i tētahi auau kua tohua. Ina huri te auau, ka taea e te tautuhinga ā-wāhanga kotahi te tohu i te hihi ki tētahi koki rerekē. Ko tēnei nekehanga tohu e whakawhirinaki ana ki te auau ka kiia ko te squint hihi. Ko te rahi o te pānga e whakawhirinaki ana ki te whānui o te whānui, te koki matawai, te hoahoa me te momo whatunga whakahaere-ā-wāhanga.

Nō reira, me nui atu i te tauākī whānui noa iho te hiahia mō te whānuitanga auau. Pātaihia te tohu hihi, te whakanui, ngā taha taha me te whakapolarisasi i runga i te auau me te koki matawai. Ko ētahi hoahoa e whakamahi ana i ngā huānga whakaroa-wā-tūturu, ngā tikanga whakarārangi iti, ngā whakatikatika e pā ana ki te auau rānei hei whakaiti i te katinga o te hihi, engari mā aua kōwhiringa ka tāpirihia ō rātou ake mate, uaua, rahi me ngā whakaritenga whakatikatika.

Kei hea te Hiranga o ngā Ngaronga o te Whatunga Whāngai

I roto i tētahi PESA monostatic noa e whakamahi ana i tētahi pūwāhi tiritahi, ka whai wāhi te whatunga whāngai ki ngā ara tuku me ngā ara whiwhi. Ka whai wāhi ngā wehewehe hiko, ngā raina tuku, ngā ara ārahi ngaru, ngā nekehanga ā-wāhanga, ngā pana me ngā whakawhiti ki te ngaronga whakaurunga. I te tuku, ka whakaitihia e ēnei ngaronga te hiko e tukuna ana ki te pūwāhi, ā, ka whakaputa wera. I te whiwhinga, ka taea e te ngaronga i mua i te kaiwhiwhi te whakaiti i te aro me te whānuitanga hihiri whai hua.

Me here ngā uara mate ki tētahi papa tohutoro mārama. Tērā pea kāore e taea te whakamahi i tētahi taura, hononga hurihuri, whakawhiti arataki ngaru, whatunga whakahaere-wāhanga, radome rānei kei roto i te pūnaha kua tāutahia, ina whakaaetia ngā raraunga ine ki te whirihoranga me te papa tohutoro kotahi i whakamahia i roto i te whakatakotoranga.

Ko te tikanga o te PESA he kotahi te auau, he kotahi rānei te whāinga?

E waru ngā pātai hei pātai i mua i te whakauru i tētahi huinga PESA

1. He aha ngā auau whakahaere me ngā whānui tere e tika ana kia tautokona, ā, ko ēhea ngā uara e hiahiatia ana puta noa i te rāngai matawai katoa?
2. He aha te azimuth me te teitei e hiahiatia ana, ā, kua whakaritea te kōhao katoa mā te mīhini, mā te hurihuri, mā te neke rānei i tētahi atu wāhi?
3. He aha ngā rohe whakanui, EIRP, whānui hihi, taha-pito me te whakawhiti-polarization e pā ana ki te tirohanga pū me te koki matawai mōrahi?
4. He aha te mana tihi, te mana toharite, te whānui o te pāorooro me te huringa mahi me whakahaere e te whatunga whāngai me te pūaha?
5. Kei hea ngā papa tohutoro mana tuku me te mana whiwhi, ā, ko ēhea ngā mate taura, te arataki ngaru, te nekehanga-ā-wāhanga me te radome kei roto?
6. Me pēhea te whakatikatika i te rarangi puta noa i te auau, te pāmahana me te koki matawai, ā, me pēhea hoki te kitea o te paheke i muri i te tāutanga?
7. He aha ngā herenga hononga, arataki ngaru, whakamau, ratōma, rahi, taumaha me ngā herenga taiao e pā ana ki te whirihoranga kua tāutahia?
8. Ko ēhea ngā inenga ka whakamanahia, ā, ka tāruatia anō e te whakaritenga whakamātautau ngā tikanga whakahaere mō te pōraritanga, te auau, te mana me te matawai?

He rerekē ngā kōwhiringa hoahoanga a te PESA me te AESA

Ka whakamahia e te PESA me te radar matawai hiko kaha ngā hononga ā-wāhanga whakahaere hei ārahi i ngā hihi. Ko tō rāua rerekētanga matua ko te wāhi e puta ai te whakaputa me te whiwhinga RF kaha. Ko te tikanga, ka arahi te PESA i tētahi hoahoa tuku me te kaiwhiwhi pokapū mā roto i tētahi whatunga whāngai me ngā kaitahuri ā-wāhanga. Ka tohatohahia e te AESA he maha ngā waeine tuku me te whiwhi kaha puta noa i te āputa, i ōna ara iti rānei. Ko te whakatinanatanga hihi—analog, ranu, mamati rānei—he taha hoahoa motuhake, ā, kaua e kiia he rite ki te wehewehenga PESA/AESA.

Ka taea e AESA te tuku i te auautanga nui ake, te ngāwari o te āhua ngaru me te whakaritenga tere o ngā mahi maha, engari ka hangaia hoki he whakaritenga uaua mō te tohatoha hiko, te whakamatao, te whakatikatika me te whakahaere kōwae. Ka taea e te PESA te noho whai hua ina tutuki i te hoahoanga RF pokapū ngā whakaritenga o te kaupapa me te whakaurunga. Mō te whakataurite hoahoa taipitopito, pānuihia ngā RF MISO.Te whakataurite i te radar AESA me te PESAMe hāngai te kōwhiringa tika ki ngā whakaritenga ka taea te ine, kaua ki te whakaaro he pai ake te kotahi whakarāpopototanga.

Me pēhea te ine me te whakaae i tētahi huinga PESA

Me tāruatia ngā tikanga e whakamahia ana i roto i te whakatakotoranga mahi e te whakamātautau whakaae. I te iti rawa, tuhia ngā pūwāhi auau, te whakapūtātanga, ngā whakahau matawai, te taumata mana, te huringa mahi, te āhua whakatikatika, te āhua radome me te papa tohutoro RF. Inehia, manatokohia rānei te whakanui, te whānui o te hihi, te tika o te tohu, ngā taha taha me te whakapūtātanga whakawhiti i ngā koki matawai e tohu ana.

Ko te whānuitanga me te whakatakotoranga e hiahiatia ana ka whakawhirinaki ki te rahi o te pūaha, te auau me te whāinga ine. Tērā pea he tika ngā tikanga mara-tawhiti, ngā tikanga mara-kikī, ngā tikanga mara-tata rānei. RF MISO'sngā āheinga whakamātautau pūihiwhakaahuahia ngā rauemi ine e tika ana, engari me whakaae te tikanga whakamutunga me te tahua koretake i mua i te tīmatanga o te whakamātautau whakaae.

Tautoko RF MISO mō te Aromatawai Pūihi Aratau

He kaihanga pūihi RF me te ngaruiti a RF MISO e tautoko ana i te rangahau pūihi, te ine me te whakaurunga pūnaha. Kāore a RF MISO e whakaatu i tētahi radar PESA katoa hei hua pūihi paerewa. Ka tīmata ngā kōrero hangarau e pā ana ki te whakatuwheratanga pūihi, te whāngai me ngā whakaritenga atanga ka taea te manatoko ki tētahi roopu auau kua tautuhia, te polarization, te whakanui, te whānui hihi me te envelopu miihini.

Ka taea e ngā miihini te arotake i te RF MISOngā hua pūihi whakararamengā pūihi papatahihei tīmatanga mō ngā kōrero mō ngā wāhanga me te whakatuwheratanga. Kāore ngā hua paerewa e wātea ana e hanga aunoa i tētahi radar PESA, ā, me whakaū te pai ki te hoahoanga pūnaha katoa.

Mō tētahi kōrero hangarau tuatahi, whakaratohia te awhi whakahaere, te whānui tere, te pōraritanga, te whakanui e hiahiatia ana, te rāngai matawai, te whāinga taha taha, te mana tihi me te mana toharite, te atanga RF, te rahi o te pūaha, ngā herenga whakairinga, ngā āhuatanga taiao me ngā tumanakohanga whakamātautau-whakaae. Mā ēnei mōhiohio ka taea e te tīma hangarau te tautuhi ko ēhea ngā antenna me ngā kōwhiringa whakamātautau e hiahia ana kia arotakehia anō.
