I roto i te tekau tau kua pahure ake nei, kua whanake te radar mirimita-ngaru (mmWave) mai i te pūoko motuhake i roto i ētahi waka papai ki te hanganga tirohanga nui i roto i ngā waka atamai. Mai i te mana whakatere urutau (ACC) me te aukati ohorere aunoa (AEB) ki te whakatere tere-teitei i runga i te pailota aunoa (NOA) me te āwhina taraiwa tāone, he mahi nui tā te radar mmWave i roto i te tirohanga taiao waka.
I te tipu haere o te hiahia mō ngā pūnaha āwhina taraiwa matatau, kei te whanake tonu ngā pūnaha radar. Kua whakakapia haeretia ngā radar rua-ahu o mua e ngā radar whakaahua 4D e taea ai te whakarato i ngā mōhiohio whānuitanga, tere, azimuth, me te teitei i te wā kotahi, me te whakatakoto i ngā whakaritenga pakari ake mō te tawhiti kitea, te taumira koki, me ngā āheinga tautuhi ūnga. Haunga ngā whakapainga i te kaha tukatuka maramara me te matatau o te raupaparorohiko, kua puta te hoahoa pūnaha pūihi hei take matua e taea ai ēnei whakapainga mahi. Hei tauira, ka tutuki i te radar whakaahua taumira teitei a Continental ARS540 te whānuitanga kitenga tata ki te 300 mita mā roto i ngā rarangi pūihi kiato teitei, me te whai i ngā rau ūnga i te wā kotahi. I roto i te motu, ka whakamahia e ngā hua radar 4D mmWave o te whakatupuranga e whai ake nei ngā pūihi rarangi nui me ngā hanganga arataki ngaru kua arotauhia hei whakarei ake i te mohiotanga ūnga tawhiti-roa, e taea ai te kite wawe i ngā waka, ngā arai, me ngā arai tūmau. I muri i ēnei whanaketanga, kua puta he ia mārama: kei te piki haere te whakamahi a ngā radar mmWave mahi-teitei i ngā hoahoanga pūihi arataki ngaru.
I roto i ngā pūnaha radar mmWave, ko te pūihi te kawenga mō te tukunga me te whiwhinga o ngā ngaru hikohiko, e pā tika ana ki te whānuitanga o te kitenga, te taumira koki, me te pono o te tohu. Ko ngā hoahoa radar mmWave o mua i whakamahi i ngā pūihi PCB microstrip nā te mea he māmā noa iho, he iti te utu, me te ngāwari o te whakaputa nui. Heoi, i te pikinga o ngā auau radar ki te 77 GHz me tua atu, ka kitea ngā herenga o ngā pūihi PCB. Ko ngā āhuatanga dielectric o ngā rauemi PCB ka puta he ngaronga horapa i ngā auau mmWave, ka whakaiti i te kaha tohu, ko ngā herenga i roto i te whai huatanga o te irahiko me ngā kaha hanga hihi ka whakawhāiti i te mahi a te pūnaha.
He rerekē, ko ngā pūihi arataki ngaru, ka ārahi i ngā ngaru hikohiko mā roto i ngā hanganga whakarewa, ka whakaiti nui i ngā ngaronga horapa me te whakatutuki i te pai ake o te irahiko. Nō reira, mō ngā pūnaha e hiahia ana ki te whānuitanga kite whānui me te taumira koki iti, kua puta ake ngā pūihi arataki ngaru hei otinga pai. Heoi, ko te whakamahinga whānui o ngā arataki ngaru ka puta mai he wero hanga hou.
He rerekē ngā pūihi PCB, he hanganga hiko whakarewa tika ngā pūihi arataki ngaru. He tino tairongo te horapa o te ngaru i roto i te arataki ngaru ki te tika o te āhua o te kōhao me te kawe hiko o roto. Ka taea e ngā rerekētanga o ngā āhua o te arataki ngaru, te taratara rānei o te mata te whakaiti i te whiwhinga, te huri i te ahunga hihi, me te whakanui ake i te ngaronga tohu, ā, ka pā ki te tawhiti kitenga radar me te mōhiotanga ūnga. Ko te hanga tuku iho e whakawhirinaki ana ki te miihini CNC, ki te mira whakarewa rānei, e whakarite ana i te mahi hiko tino tika engari he nui ngā herenga o te utu me te tauine. Ko ngā hanganga ngaru-mirimita, he torutoru mirimita noa te rahi me ngā manawanui o te tekau maikoroni, e hiahia ana ki ngā mīhini matatau me te whakahaere tukanga pai. He pai te miihini miihini ki te hanga tauine iti engari ka aukati i ngā radar motuka hokohoko nui, i ngā pūoko kaihoko rānei.
Hei whakataurite i te mahi hikohiko teitei me te āheinga hanga, kua tūhuratia e te umanga ngā pūihi arataki ngaru whakarewa. Ko te ariā matua ko te wehe i te hanganga hanganga mai i te kawe hiko. Engari i te miihini i te poraka whakarewa katoa, ka whakamahia e te huarahi te "hanganga hanganga + whakarewa mata."
I te tīmatanga, ka hangaia te kōhao arataki ngaru mā te whakamahi i te whakahāngai werohanga, te whakahāngai kōpeketanga, te hanga tāpiri rānei me ngā kirihou hangarau, ngā pūmua mahi-teitei rānei, e tuku ana i te ngāwari me te pai mō te whakaputa nui. I muri i te hanganga hanganga, ka whakamahia te maimoatanga-mua o te mata—te horoi, te whakahāngai, te whakahohenga matū rānei—hei whakarei ake i te piri o te konganuku. Ko te whakatakotoranga i muri mai o tētahi paparanga arataki tonu, mā te PVD, te whakakikorua hiko, te whakakikorua kore-hiko rānei, me te parahi, te nikara, te hiriwa rānei, ka huri i te hanganga hei arataki ngaru arataki iti-ngaronga. Ko ngā wāhi matua pēnei i ngā kōhao hihi, ngā rohe atanga rānei, ka whiwhi pea i te whakahāngai ā-rohe, i te miihini pai rānei hei whakapai ake i te mahi hikohiko.
Mā tēnei huarahi "hanganga + whakarewatanga" ka mau tonu te mahi teitei o ngā arataki ngaru tuku iho, me te āhei hoki ki te whakaputa ngāwari, whai hua. Mā ngā wāhanga werohanga-whakarewa ka taea te hanga tere i te papatipu, ka whakaiti i ngā utu; ka whakaitihia te taumaha e ngā papa kirihou, ka tautoko i te whakamama i ngā motuka, ā, mā te tā 3D ka taea te whakahaere i ngā āhuahanga uaua, ka whakarei ake i te hoahoa o ngā rarangi pūihi nui. Ka angitu te whakataurite i te pai o te hikohiko, te kaha hanga, me te whakahaere utu, ka nui haere te whakamahinga o ngā pūihi arataki ngaru whakarewa i roto i ngā hua radar mmWave.
Ka whakaratohia e Zhihua Vacuum ngā otinga whānui mō te hanga atamai o ngā pūihi arataki ngaru radar mmWave kua whakarewahia. Ko tā rātou raina whakaputa paninga tonu whakapae, e hangai ana ki te pupuhi korehau, ka tutuki te whakatakotoranga whakarewa rua-paparanga, maha-paparanga rānei i roto i te huringa korehau kotahi me te whakahaere tika me te ōritetanga. Ki te whakatauritea ki te tānga hiko hiriwa tuku iho, ka whakarei ake ngā hiko parahi magnetron-sputtered i te kawe hiko, te pono, me te mahi anti-whanariki me te whakaiti i te utu. Ko te whakahaere aunoa me te hototahi ki ngā rahi uku rerekē ka whakarite kia nui te rere mō te whakaputa papatipu. Neke atu i te 30 tau i roto i ngā hangarau paninga korehau, tae atu ki te PVD, PECVD, me te ALD, ka tukuna e Zhihua Vacuum te whakaurunga tukanga kua whakaritea, huna mai i te R&D tae noa ki te whakaputa papatipu.
I te whanaketanga o ngā hangarau taraiwa motuhake me ngā hangarau pūoko atamai, kei te piki haere tonu ngā tono mō te mahi radar mmWave. Ko te whanaketanga mai i ngā pūihi PCB microstrip ki ngā pūihi arataki ngaru, ā, ināianei ki ngā hanganga arataki ngaru whakarewa, e whakaata ana i te tūranga nui o te hangarau hanga pūihi. Mā te wehewehe i te hanganga hanganga mai i te mahi kawe, ka tutuki i ngā pūihi arataki ngaru whakarewa te mahi hikohiko teitei me te pai o te whakaputa, e tuku ana i te ngāwari mō ngā hoahoa radar rarangi matatini. I te whanaketanga o te pūtaiao rauemi me ngā tikanga hanga, kua rite tēnei huarahi ki te whai wāhi nui ake i roto i ngā pūnaha radar mmWave a meake nei.
