Main lobe width
Kune chero antenna, kazhinji, iyo yepamusoro kana pamusoro penzira yekutungamira inowanzoita petal chimiro, saka iyo yekutungamira iyo inonziwo lobe pateni.Iyo lobe ine yakakwira mwaranzi gwara inodaidzwa kuti main lobe, uye yasara inonzi side lobe.
Iyo hupamhi hwelobe inokamurwazve kuita hafu simba (kana 3dB) lobe upamhi uye zero simba lobe upamhi.Sezvinoratidzwa mumufananidzo uri pasi apa, kumativi ose maviri ekukosha kukuru kweiyo huru lobe, Angle pakati pemativi maviri apo simba rinodonha kusvika hafu (0.707 nguva dzemunda wakasimba) inonzi hafu-simba lobe upamhi.
Iyo Angle pakati pemativi maviri umo simba kana simba remunda rinodonha kusvika kune yekutanga zero inonzi zero-simba lobe upamhi.
Antenna polarization
Polarization chinhu chakakosha cheantenna.Iyo yekufambisa polarization yeantenna ndiyo inofamba mamiriro emagetsi emunda vector endpoint yeantenna inopenya inopenya electromagnetic wave mune ino nzira, uye iyo inogamuchira polarization ndiyo inofamba mamiriro emagetsi emunda vector endpoint yekugamuchira antenna chiitiko ndege wave mune ino. direction.
Iyo polarization yeantenna inoreva kupora kweiyo chaiyo yemunda vector yeredhiyo wave, uye mafambiro enzvimbo yekupedzisira yemagetsi field vector munguva chaiyo, ine hukama negwara renzvimbo.Iyo antenna inoshandiswa mukuita inowanzoda polarization.
Polarization inogona kukamurwa kuita mutsara polarization, denderedzwa polarization uye elliptic polarization.Sezvinoratidzwa mumufananidzo uri pasi apa, apo trajectory yemagumo emagetsi emagetsi mumufananidzo (a) mutsara wakatwasuka, uye Angle pakati pemutsara uye X-axis haishanduki nenguva, iyi polarized wave inonzi. linearly polarized wave.
Kana ichicherechedzwa munzira yekuparadzira, kutenderera kwewachi kwemagetsi emunda wemagetsi kunonzi kurudyi-ruoko circularly polarized wave, uye kutenderera kunotenderera kunonzi kutenderera-kuruboshwe-kutenderera polarized wave.Kana ikacherechedzwa ichipikisa kwainopararira, masaisai erudyi anotenderera achitarisa wachi uye masaisai eruboshwe anotenderera achitarisa wachi.
Radar zvinodiwa kune antennas
Seye radar antenna, basa rayo ndere kushandura iyo inotungamirwa wave ndima inogadzirwa neinotumira munzvimbo yemwaranzi nzvimbo, kugamuchira iyo echo inotaridzwa kumashure nechinangwa, uye kushandura simba reiyo echo kuita inotungamirwa wave ndima kuti itumire kune inogamuchira.Izvo zvinodikanwa zveradar zveantenna zvinowanzo sanganisira:
Inopa shanduko yesimba inoshanda (yakayerwa mukuita kweantenna) pakati penzvimbo yemwaranzi yenzvimbo uye tambo yekutapurirana;Kunyanya kushanda kweantenna kunoratidza kuti iyo RF simba inogadzirwa neiyo transmitter inogona kushandiswa nemazvo
Kugona kutarisisa yakakwira-frequency simba munzira yechinangwa kana kugamuchira yakakwira-frequency simba kubva munzira yechinangwa (kuyerwa mune antenna kuwana)
Kugoverwa kwesimba kwenzvimbo yemwaranzi yenzvimbo munzvimbo inogona kuzivikanwa zvinoenderana nebasa remhepo re radar (inoyerwa neantenna dhairekitori).
Iyo yakanakira polarization control inofanana neiyo polarization maitiro echinangwa
Yakasimba mechanical chimiro uye flexible operation.Kuongorora nzvimbo yakatenderedza kunogona kunyatso kuteedzera zvinangwa uye kudzivirira kubva kumhepo
Sangana nehunyanzvi zvinodiwa senge kufamba, kureruka kwecamouflage, kukodzera kwezvinangwa chaizvo, nezvimwe.
