Zvinhu zvine tembiricha chaiyo pamusoro pe zero yakakwana zvinopenya simba. Huwandu hwesimba rinopenya rinowanzo kuratidzwa mutembiricha yakaenzana TB, inowanzonzi tembiricha yekupenya, inotsanangurwa se:
TB ndiyo tembiricha yekupenya (tembiricha yakaenzana), ε ndiko kuburitsa, Tm ndiyo tembiricha chaiyo yemamorekuru, uye Γ ndiyo yepasi pemhepo inoburitsa coefficient ine chekuita nepolarization yemafungu.
Sezvo iyo emissivity iri mukati menguva [0,1], iyo yakanyanya kukosha iyo tembiricha yekupenya inogona kusvika yakaenzana nekushisa kwema molecular. Muzhinji, iyo emissivity ibasa rekushanda frequency, polarization yesimba rakaburitswa, uye chimiro chemamorekuru echinhu. Pama microwave frequencies, zvinobudisa zvesimba zvakanaka ivhu rine tembiricha yakaenzana ingangoita 300K, kana denga riri kudivi rezenith rine tembiricha yakaenzana ingangoita 5K, kana denga munzira yakachinjika ye100~150K.
Iyo tembiricha yekupenya inoburitswa neakasiyana mwenje masosi inobatwa neantenna uye inoonekwa paantennakupera muchimiro chekushisa kweantenna. Iyo tembiricha inoonekwa kumagumo antenna inopihwa zvichibva pane iri pamusoro fomula mushure mekuyera antenna kuwana pateni. Inogona kuratidzwa se:
TA ndiyo tembiricha yeantenna. Kana pasina kukanganisa kurasikirwa uye mutsara wekutumira pakati peantenna neanogamuchira hauna kurasikirwa, simba reruzha rinoendeswa kune anogamuchira ndere:
Pr ndiyo antenna ruzha simba, K ndiyo yeBoltzmann inogara, uye △f ndiyo bandwidth.
mufananidzo 1
Kana tambo yekufambisa pakati peantenna neanogamuchira yarasika, iyo antenna ruzha simba rinowanikwa kubva pane iri pamusoro fomula rinoda kugadziriswa. Kana iyo chaiyo tembiricha yemutsetse wekutumira yakafanana neT0 pamusoro pehurefu hwose, uye attenuation coefficient yemutsara wekutumira unobatanidza antenna uye mugamuchiri inogara α, sezvinoratidzwa mumufananidzo 1. Panguva ino, antenna inoshanda. tembiricha pamugumo wekugamuchira ndeye:
Kupi:
Ta ndiyo tembiricha yeantenna painogashira tembiricha, TA ndiyo tembiricha yeruzha rweantenna panogumira antenna, TAP ndiyo tembiricha yeantenna patembiricha yemuviri, Tp ndiyo tembiricha yeantenna yemuviri, eA ndiyo antenna yekupisa kwekushisa, uye T0 ndiyo yemuviri. tembiricha yemutsetse wekutapurirana.
Naizvozvo, iyo antenna ruzha simba rinoda kugadziriswa kuti:
Kana iyo inogashira pachayo iine imwe tembiricha yeruzha T, iyo system ruzha simba pane inogamuchira endpoint ndeye:
Ps ndiyo system ruzha simba (panzvimbo yekugamuchira yekupedzisira), Ta ndiyo tembiricha yeruzha rweantenna (panzvimbo inogashira), Tr ndiyo tembiricha yeruzha rweruzha (panzvimbo inogashira yekugamuchira), uye Ts ndiyo system inoshanda ruzha tembiricha. (panzvimbo yekupedzisira yekugamuchira).
Mufananidzo 1 unoratidza hukama pakati pese parameters. Iyo sisitimu inoshanda ruzha tembiricha Ts yeantenna uye inogamuchira yeredhiyo yekuongorora nyeredzi inotangira kubva kune mashoma K kusvika akati wandei zviuru K (yakajairika kukosha ingangoita 10K), iyo inosiyana nerudzi rweantenna uye inogamuchira uye frequency yekushandisa. Shanduko yetembiricha yeantenna pamugumo weantenna inokonzerwa nekushandurwa kwemwaranzi inotangwa inogona kunge idiki sezvikamu zvishoma zvegumi zveK.
Iyo tembiricha yeantenna pane yekupinda antenna uye iyo inogamuchira yekupedzisira poindi inogona kusiyana nemadhigirii mazhinji. Kureba kupfupi kana kuderera-kurasikirwa kutapurirana tambo kunogona kuderedza zvakanyanya kusiyana kwetembiricha iyi kusvika kudiki sezvikamu zvishoma zvegumi zvedhigirii.
