Izinzuzo kanye nokungalungi kwemitha yezinga le-radar uma kuqhathaniswa nemitha yezinga le-ultrasonic

I-radarimitha yezingakanye nemitha yezinga le-ultrasonic yizinto ezivame ukusetshenziswa zokulinganisa izinga, okulandelayo izinzuzo kanye nokungalungi kwemitha yezinga le-radar uma kuqhathaniswa nemitha yezinga le-ultrasonic:
inzuzo
Ukunemba okuphezulu kokulinganisa: imitha yezinga le-radar isebenzisa isimiso sokubonakaliswa kwe-microwave ukukala, okungathinteki izinguquko ekushiseni, ingcindezi, ubuningi, umswakama kanye nezinye izinto, futhi ukunemba kokulinganisa kuphakeme, ngokuvamile kufika ku-±1mm noma ngaphezulu. Ukunemba kokulinganisa kwemitha yezinga le-ultrasonic kuthinteka kakhulu yizici ezifana nezici eziphakathi nendawo kanye nokushisa okuzungezile, futhi ukunemba kuvame ukuba cishe ku-± 3mm-± 5mm.
Uhla olubanzi lwezicelo
Ukuzivumelanisa nezimo okumaphakathi: Imitha yezinga le-radar ingalinganisa izinga loketshezi lwezinto ezahlukahlukene zoketshezi neziqinile, okuhlanganisa ukugqwala, ukujiya, ukukristala okulula kanye nezinye izinto ezikhethekile. Lapho ilinganisa i-medium ene-viscosity ephezulu, ukukristala okulula noma i-foam, imitha yezinga le-ultrasonic ingaba nokuncipha kwesignali noma ukubonakaliswa okungazinzile.
Indawo yokushisa okuphezulu kanye nendawo yokucindezela okuphezulu: imitha yezinga le-radar ingasebenza ngokuzinzile endaweni enzima yokushisa okuphezulu (kufika ku-400℃ noma ngaphezulu) kanye nokucindezela okuphezulu (kufika ku-40MPa noma ngaphezulu). Ngenxa yokulinganiselwa kwezinto ze-transducer kanye nesimiso, ububanzi bokusetshenziswa kwemitha yezinga loketshezi lwe-ultrasonic endaweni yokushisa okuphezulu kanye nendawo yokucindezela okuphezulu buncane kakhulu.
Ibanga elikhulu: Ibanga lokulinganisa lemitha yezinga le-radar likhulu, ngokuvamile elingafinyelela amashumi amamitha noma ngisho namakhulu amamitha, futhi lifanelekela ukulinganisa izinga loketshezi lwamathangi amakhulu okugcina kanye nemibhoshongo emide. Ibanga lokulinganisa elisebenzayo lemitha yezinga le-ultrasonic ngokuvamile lingaphakathi kwamamitha ayishumi.
Amandla aqinile okulwa nokuphazamiseka: isignali ye-microwave ekhishwa yimitha yezinga le-radar ayiphazanyiswa amaza kagesi angaphandle, amaza omsindo nezinye izimpawu, futhi isignali izinzile futhi ithembekile. Endaweni enomsindo onamandla, ukudlidliza noma umusi, imitha yezinga le-ultrasonic ithambekele ekuphazamisekeni, okuholela ekwandeni kwephutha lokulinganisa.
Izidingo zokufakwa ziphansi kakhulu: imitha yezinga le-radar ayizweli ezinkingeni nasezintweni ezibangela ukuvuvukala esitsheni lapho ifakiwe, inqobo nje uma i-antenna ingavaliwe. Imitha yezinga le-Ultrasonic ayidingi zinkingeni ezingaphezu kwezinga loketshezi, ngaphandle kwalokho izothinta ukusabalala nokubonakaliswa kwamagagasi omsindo, okuholela ekulinganisweni okungafanele.
Isikhundla esiphansi
Intengo ephezulu: Okuqukethwe kobuchwepheshe bemitha yezinga le-radar kuphakeme, futhi inqubo yokukhiqiza iyinkimbinkimbi, ngakho-ke intengo ibiza kakhulu kunemitha yezinga le-ultrasonic, ekhawulela ububanzi bokusetshenziswa kwayo ngezinga elithile, ikakhulukazi kwezinye izimo ezibucayi.
Kunzima ukulinganisa i-medium nge-dielectric constant encane: ku-medium ene-dielectric constant encane, isignali eboniswayo yegagasi le-radar ibuthakathaka, okungase kuthinte ukunemba kokulinganisa. Imitha yezinga loketshezi lwe-ultrasonic ayizweli ku-dielectric constant ye-medium, futhi ifaneleka kakhulu ukulinganisa i-medium ngezinguquko ezinkulu noma ezincane ku-dielectric constant.
Kukhona indawo engaboni: imitha yezinga le-radar inendawo ethile engaboni eduze nendawo yokuqala yokulinganisa, ngokuvamile amashumi amasentimitha kuya cishe kumitha elilodwa, futhi ayikwazi ukukala izinga loketshezi eduze kakhulu nephansi. Indawo engaboni yemitha yezinga le-ultrasonic incane kakhulu, ngokuvamile phakathi kwamasentimitha ambalwa namashumi amasentimitha.
Ukungena kabi kwesignali: amaza e-radar awakwazi ukungena ezintweni ezikhanyayo eziqinile njengensimbi, uma isitsha singesensimbi futhi ungqimba lwangaphakathi noma ungqimba lokufaka, kungathinta ukusabalala nokubonakaliswa kwamaza e-radar, kudingeke usebenzise indlela ekhethekile yokufaka noma ukhethe imodeli efanele yesilinganiso sezinga le-radar. Igagasi lomsindo lemitha yezinga le-ultrasonic lingangena ebukhulu obuthile bezinto ezingezona ezensimbi, futhi ukuzivumelanisa nezimo kwezinto zesitsha kanye nesakhiwo kuhle kakhulu.
