Mumakore gumi apfuura, radar ye millimeter-wave (mmWave) yakashanduka kubva pakuva sensor iri nyore mumotokari shoma dzemhando yepamusoro kuenda pakuva zvivakwa zvakakosha zvekuona mumotokari dzakangwara. Kubva pa adaptive cruise control (ACC) uye automatic emergency braking (AEB) kusvika pakufamba nekukurumidza kuri kuramba kuchiitika pa autopilot (NOA) uye rubatsiro rwekutyaira mumaguta, mmWave radar ine basa guru pakuona nharaunda yemotokari.
Sezvo kudiwa kwemasisitimu epamusoro ekubatsira mutyairi kuri kuwedzera, masisitimu eradar pachawo ari kuramba achichinja. Maradar ekutanga ane mativi maviri akatsiviwa zvishoma nezvishoma nemaradar e4D ekufungidzira anokwanisa kupa ruzivo rwekureruka, kumhanya, azimuth, uye kukwirira panguva imwe chete, zvichiisa zvinodiwa zvakanyanya pakuona daro, kugona kwekona, uye kugona kuziva chinangwa. Kupfuura kuvandudzwa kwesimba rekugadzirisa machip uye algorithm, dhizaini yesystem yeantenna yakabuda sechinhu chakakosha chinoita kuti izvi zviwedzere kushanda. Semuenzaniso, radar yeContinental yekufungidzira ine resolution yepamusoro ARS540 inosvika padanho rekuona rinosvika 300-mita kuburikidza nearrays dzeantena dzakasimba, panguva imwe chete ichitevera mazana ezvinangwa. Munyika, zvigadzirwa zveradar zve4D mmWave zvechizvarwa chinotevera zvinoshandisa maantenna makuru uye maumbirwo ewaveguide akagadziridzwa kuti zviwedzere kuzivikanwa kwechinangwa kwenguva refu, zvichigonesa kuonekwa kwemotokari kare, guardrails, uye zvipingamupinyi zvisingachinji. Kumashure kwekufambira mberi uku, maitiro akajeka akabuda: maradar emmWave anoshanda zvakanyanya ari kuwedzera kushandisa magadzirirwo eantenna ewaveguide.
Mumasystem e mmWave radar, antenna ndiyo inokonzera kuburitswa uye kugamuchira mafungu emagetsi, zvichikanganisa zvakananga huwandu hwekuona, angular resolution, uye kuvimbika kwechiratidzo. Magadzirirwo ekutanga e mmWave radar ainyanya kushandisa maPCB microstrip antennas nekuda kwekureruka kwawo, mutengo wakaderera, uye nyore kwekugadzirwa kukuru. Zvisinei, sezvo mafrequency eradar achikwira kusvika ku77 GHz uye kupfuura, miganhu yePCB antennas inova pachena. Hunhu hwe dielectric hwezvinhu zvePCB hunounza kurasikirwa kwekupararira pa mmWave frequency, zvichideredza simba rechiratidzo, nepo zvipingamupinyi mukushanda zvakanaka kwemwaranzi uye kugona kwe beamforming zvichiganhurira mashandiro esystem.
Kusiyana neizvi, maantenna eWaveguide anotungamira mafungu emagetsi kuburikidza nesimbi, zvichideredza zvakanyanya kurasikirwa nekupararira uye kuwana kushanda zvakanaka kwemwaranzi. Nekuda kweizvozvo, kune masisitimu anoda huwandu hwakareba hwekuona uye kugona kwakanaka kwemakona, maantenna ewaveguide ave mhinduro inofarirwa. Asi kushandiswa kwakapararira kwemawaveguide kunounza matambudziko matsva ekugadzira.
Kusiyana nemaantenna ePCB, maantenna ewaveguide magadzirirwo emagetsi esimbi akanyatsogadzirwa. Kupararira kwemafungu mukati mewaveguide kunonyanya kunzwisiswa nekunyatsojeka kwenzvimbo dzakavharika uye kufambiswa kwemhepo mukati. Kutsauka muhukuru hwewaveguide kana kushata kwepamusoro kunogona kuderedza kukwira, kutsausa divi remwenje, uye kuwedzera kurasikirwa kwechiratidzo, zvichizokanganisa daro rekuona radar uye kuzivikanwa kwechinangwa. Kugadzirwa kwechinyakare kunoenderana neCNC machining kana simbi milling, iyo inovimbisa kushanda kwakarurama kwemagetsi asi inotarisana nemiganhu yakakura mumutengo uye kugona kukura. Maumbirwo emafungu emamiriyoni, anowanzova mamirimita mashoma muhukuru ane ma microns makumi, anoda michina yakaoma uye kudzora mashandiro akanaka. Kugadzira kwemechanical kunokodzera kugadzirwa kudiki asi kunova kwakaoma kune ma radar emotokari akawanda kana ma sensor evatengi.
Kuti vawirirane nekushanda nesimba kwemagetsi nekugadzirwa kwezvinhu, indasitiri iyi yakaongorora maantenna esimbi ane mawaveguide. Pfungwa huru ndeyekubvisa kuumbwa kwechimiro kubva pakufambiswa kwemagetsi. Pane kugadzira simbi yese, nzira iyi inoshandisa "kuumbwa kwechimiro + kugadzirwa kwesimbi pamusoro."
Pakutanga, nzvimbo ye waveguide inoumbwa uchishandisa jekiseni rekugadzira, compression molding, kana kugadzirwa kwekuwedzera nepurasitiki yeinjiniya kana mapolymer ane mashandiro epamusoro, zvichipa kuchinjika uye kukodzera kugadzirwa kwepamusoro. Mushure mekugadzirwa kwechimiro, kugadziriswa kwepamusoro-soro—kuchenesa, kukwesha, kana kushandiswa kwemakemikari—kunoiswa kuti simbi inamatire. Kuiswa kwechikamu chinoenderera mberi che conductive layer, kuburikidza nePVD, electroplating, kana electroless plating, kazhinji nemhangura, nickel, kana sirivha, kunoshandura chimiro kuita conductive waveguide ine kurasikirwa kwakaderera. Nzvimbo dzakakosha dzakadai se radiating apertures kana interface regions dzinogona kugamuchira localized metallization kana fine machining kuti iwedzere electromagnetic performance.
Iyi nzira ye "chimiro + metallization" inoramba ichishanda zvakanaka sema waveguides echinyakare uku ichigonesa kugadzirwa kunochinjika uye kunobudirira. Zvikamu zvakaumbwa nejekiseni zvinobvumira kugadzirwa nekukurumidza, zvichideredza mitengo; mapurasitiki anoderedza huremu, achitsigira kurema kwemotokari, uye kudhinda kwe3D kunobatsira ma geometries akaomarara, zvichivandudza dhizaini yema antenna makuru. Nzira iyi inobudirira kuenzanisa kushanda kwe electromagnetic, kugadzirwa, uye kudzora mitengo, zvichiita kuti ma waveguides esimbi awedzere kuwanda muzvigadzirwa zve mmWave radar.
Zhihua Vacuum inopa mhinduro dzakakwana dzekugadzira zvine hungwaru maantenna e mmWave radar radar waveguide. Mutsetse wavo wekugadzira coating unoenderera mberi, wakavakirwa pa vacuum sputtering, unowana dual-kana multi-layer metallic deposition mu vacuum cycle imwe chete nekudzora kwakaringana uye kugadzikana. Zvichienzaniswa nekudhinda kwesirivha electrode yechinyakare, ma electrode emhangura ane magnetron-sputtered conductivity anowedzera conductivity, kuvimbika, uye anti-sulfuration performance ukuwo achideredza mutengo. Kubata otomatiki uye kuenderana nehukuru hwakasiyana hweceramic kunoita kuti pave ne throughput yakakwira yekugadzira zvakawanda. Nemakore anopfuura makumi matatu mu vacuum coating antennas, kusanganisira PVD, PECVD, uye ALD, Zhihua Vacuum inopa kubatanidzwa kwakagadzirirwa, kwakavanzika kubva kuR&D kuburikidza nekugadzira zvakawanda.
Sezvo tekinoroji yekutyaira yega uye yekunzwa kwehungwaru ichifambira mberi, zvinodiwa pakushanda kweradar yemmWave zviri kuramba zvichikwira. Kushanduka kubva kumaantena ePCB microstrip kuenda kumaantena ewaveguide, uye ikozvino kusvika kumagadzirirwo emawaveguide esimbi, zvinoratidza basa rakakosha retekinoroji yekugadzira maantena. Nekuparadzanisa kugadzirwa kwechimiro kubva pakushanda kwekufambisa, maantena ewaveguide esimbi anowana kushanda kwepamusoro kwemagetsi uye kugona kugadzira, zvichipa kuchinjika kwemagadzirirwo akaomarara eradar. Sezvo sainzi yezvinhu uye matekiniki ekugadzira achifambira mberi, nzira iyi yakagadzirira kutamba basa rakakosha mune remangwana re mmWave radar systems.
