Izinto ezinamazinga okushisa angempela angaphezu kukaziro ophelele zizokhipha amandla. Inani lamandla aphumayo livamise ukuvezwa ngezinga lokushisa elifanayo le-TB, ngokuvamile elibizwa ngokuthi izinga lokushisa lokukhanya, elichazwa ngokuthi:
I-TB izinga lokushisa lokukhanya (izinga lokushisa elilinganayo), ε i-emissivity, i-Tm izinga lokushisa lengqamuzana langempela, futhi u-Γ yi-coefficient ephuma ngaphandle ehlobene nokuhlukaniswa kwegagasi.
Njengoba ukukhishwa komoya kungaphakathi kwesikhawu [0,1], inani eliphezulu izinga lokushisa lokukhanya elingafinyelelwa kulo lilingana nezinga lokushisa lamangqamuzana. Ngokuvamile, ukukhishwa kwe-emissivity kuwumsebenzi wemvamisa yokusebenza, i-polarization yamandla akhishiwe, kanye nokwakheka kwama-molecule ento. Kumafrikhwensi e-microwave, abakhiphi bemvelo bamandla amahle bawumhlaba onezinga lokushisa elilinganayo elicishe libe ngu-300K, noma isibhakabhaka sibheke endaweni eshisa izikhotha enezinga lokushisa elilingana no-5K, noma isibhakabhaka endaweni evundlile engu-100~150K.
Izinga lokushisa lokukhanya elikhishwa imithombo yokukhanya ehlukene libanjwa uthi bese livela ku-uthigcina ngesimo sokushisa kwe-antenna. Izinga lokushisa elivela ekugcineni kwe-antenna linikezwa ngokususelwe kufomula engenhla ngemva kokukala iphethini yokuzuza uthi. Ingavezwa ngokuthi:
I-TA izinga lokushisa le-antenna. Uma kungekho ukulahlekelwa okungafani futhi ulayini wokudlulisela phakathi kothi nomamukeli ungalahleki, amandla omsindo adluliselwa kumamukeli yilawa:
I-Pr amandla omsindo we-antenna, i-K iyi-Boltzmann engaguquki, futhi △f iwumkhawulokudonsa.
umfanekiso 1
Uma ulayini wokudlulisela phakathi kwe-antenna nomamukeli ulahlekile, amandla omsindo we-antenna atholwe kufomula engenhla adinga ukulungiswa. Uma izinga lokushisa langempela lomugqa wokudlulisela lifana ne-T0 kubo bonke ubude, futhi i-coefficient yokunciphisa umugqa wokudlulisela oxhuma i-antenna nomamukeli ingu-α njalo, njengoba kuboniswe kuMfanekiso 1. Ngalesi sikhathi, i-antenna esebenzayo izinga lokushisa endaweni yokugcina yomamukeli yile:
Kuphi:
I-Ta yizinga lokushisa le-antenna endaweni yokugcina eyamukelayo, i-TA izinga lokushisa lomsindo we-antenna ekugcineni kwe-antenna, i-TAP izinga lokushisa le-antenna ekugcineni lokushisa lomzimba, i-Tp izinga lokushisa lomzimba le-antenna, i-eA iyi-antenna esebenza kahle, futhi i-T0 iyizinga lokushisa elingokomzimba. izinga lokushisa lomugqa wokudlulisela.
Ngakho-ke, amandla omsindo we-antenna adinga ukulungiswa ukuze:
Uma umamukeli ngokwaso enezinga lokushisa elithile lomsindo elingu-T, amandla omsindo wesistimu endaweni yokugcina yomamukeli athi:
I-Ps amandla omsindo wesistimu (esikhundleni sokugcina somamukeli), i-Ta iyizinga lokushisa lomsindo we-antenna (esikhungweni sokugcina somamukeli), i-Tr izinga lokushisa lomsindo owamukelayo (endaweni yokugcina yomamukeli), futhi i-Ts iyisistimu yokushisa yomsindo esebenzayo. (ekugcineni komemukeli).
Umfanekiso 1 ubonisa ubudlelwano phakathi kwawo wonke amapharamitha. Isistimu yokushisa yomsindo ephumelelayo i-T yothi kanye nomamukeli wesistimu yezinkanyezi zomsakazo isukela ku-K ezimbalwa kuya ezinkulungwaneni ezimbalwa K (inani elijwayelekile licishe libe ngu-10K), elihluka ngohlobo lwe-antenna nomamukeli kanye nefrikhwensi yokusebenza. Ushintsho kuzinga lokushisa le-antenna endaweni yokugcina ye-antenna olubangelwa ukushintsha kwemisebe eqondiwe kungaba kuncane njengezingxenye eziyishumi ezimbalwa ze-K.
Izinga lokushisa le-antenna kokokufaka kwe-antenna nendawo yokugcina eyamukelayo ingahluka ngamadigri amaningi. Ulayini wokudlulisa obude obufushane noma olahlekelwe kancane unganciphisa kakhulu lo mehluko wezinga lokushisa ube mncane njengezingxenye eziyishumi ezimbalwa zedigri.
RF MISOiyibhizinisi lobuchwepheshe obuphezulu elisebenza nge-R&D kanyeukukhiqizwayezimpondo nemishini yokuxhumana. Sizibophezele ku-R&D, ukusungula izinto ezintsha, ukuklama, ukukhiqizwa nokuthengiswa kwezinti kanye namadivayisi okuxhumana. Ithimba lethu lakhiwe ngodokotela, ongcweti, onjiniyela abakhulu nabasebenzi abaphambili abanamakhono, abanesisekelo esiqinile sethiyori esisebenzayo kanye nolwazi olucebile olusebenzayo. Imikhiqizo yethu isetshenziswa kabanzi kwezohwebo, ekuhloleni, ezinhlelweni zokuhlola nakwezinye izinhlelo zokusebenza eziningi. Ncoma imikhiqizo eminingi yezimpondo esebenza kahle kakhulu:
I-RM-BDHA26-139(2-6GHz)
RM-LPA054-7(0.5-4GHz)
I-RM-MPA1725-9(1.7-2.5GHz)
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
