M'dziko laukadaulo wa radar, chitukuko cha makina opangira ma radar asintha kwambiri momwe timadziwira ndikutsata zinthu zakumwamba. Makinawa amapereka kusinthasintha kochulukira, magwiridwe antchito abwino, komanso kuthekera kopitilira muyeso poyerekeza ndi makina akale a radar. Chimodzi mwazinthu zazikulu zomwe zathandizira kupititsa patsogolo luso laukadaulo wa radar ndi microstrip circulator.
Makina opangira ma radar apakati amagwiritsa ntchito tinyanga zingapo potumiza ndi kulandira ma siginecha a wailesi. Ma antennas awa amasanjidwa motsatana pang'onopang'ono, kulola chiwongolero chamitengo yamagetsi ndi kuwongolera. Izi zimathandiza kuti makina a radar azitha kuyang'ana mwachangu malo ozungulira, kutsata zolinga zingapo nthawi imodzi, ndikusintha zomwe zikufunika kusintha.
Microstrip circulator ndi gawo lofunikira mkati mwa dongosolo la radar lokhazikika. Ndi chipangizo chongolankhula, chosasinthasintha chomwe chimalola kuti ma siginecha a RF aziyenda bwino mkati mwa radar system. Wozungulira amaonetsetsa kuti zizindikiro zomwe zimatumizidwa zimatumizidwa ku tinyanga kuti zitumizidwe komanso kuti zizindikiro zolandilidwa zimatumizidwa kwa wolandira kuti akonze. Kugwira ntchito kumeneku ndikofunikira kuti ma radar agwire bwino ntchito ndikukulitsa magwiridwe ake.
Ubwino umodzi wogwiritsa ntchito ma microstrip circulators m'makina ophatikizika a radar ndi kukula kwawo kocheperako komanso kulemera kochepa. Ma circulator achikhalidwe ndi ochulukirapo komanso olemetsa, kuwapangitsa kukhala osayenera kuphatikizidwa ndi makina amakono a radar omwe amaika patsogolo kusuntha ndi kuyenda. Komano, ma Microstrip circulators amapangidwa kuti azikhala opepuka komanso ophatikizika, kuwapangitsa kukhala abwino kuti agwiritsidwe ntchito pamakina opangira ma radar omwe amayikidwa pamapulatifomu am'manja monga ndege, zombo, ndi magalimoto oyenda pansi.
Kuphatikiza apo, ma circulator a microstrip amapereka mawonekedwe abwino kwambiri, kuphatikiza kutayika kotsika, kudzipatula kwambiri, komanso bandwidth yayikulu. Makhalidwewa ndi ofunikira pakuwonetsetsa kutumiza ndi kulandira ma siginecha a RF mu radar system. Kutayika kwapang'onopang'ono kumachepetsa kutayika kwa mphamvu ya chizindikiro pamene ikudutsa pa circulator, pamene kudzipatula kwakukulu kumalepheretsa kutuluka kwa chizindikiro kosafunikira, kuonetsetsa kukhulupirika kwa ntchito ya radar. Kuphatikiza apo, kuthekera kokulirapo kwa bandwidth kumalola kuti makina a radar azigwira ntchito mosiyanasiyana, ndikupangitsa kuti ikhale yosunthika komanso yogwirizana ndi zochitika zosiyanasiyana.
Kuphatikizika kwa ma microstrip circulators kukhala ma radar array array system kwathandiziranso kupita patsogolo kwaukadaulo wa radar, zomwe zapangitsa kuti pakhale luso lowonjezereka monga nkhondo yamagetsi, kuzindikiritsa chandamale, ndi kulondola kolondola. Chikhalidwe chosasinthika cha circulator chimalola kukhazikitsidwa kwa njira zamakono zopangira ma sigino, monga kuthamanga kwafupipafupi ndi kusiyanasiyana kwa polarization, zomwe ndizofunikira kuti machitidwe amakono a radar athane ndi zotsutsana ndi zamagetsi ndikukhalabe ogwira ntchito m'madera ovuta a electromagnetic.
Pomaliza, kuphatikizika kwa ma microstrip circulator m'makina ophatikizika a radar kwapititsa patsogolo luso komanso magwiridwe antchito aukadaulo wa radar. Zida zophatikizika, zopepuka, komanso zowoneka bwino kwambiri izi zathandizira kupanga makina apamwamba kwambiri a radar omwe amapereka kusinthasintha kowonjezereka, kuwongolera magwiridwe antchito, komanso luso lapamwamba lolondolera chandamale. Pamene kufunikira kwa makina apamwamba a radar kukukulirakulira, gawo la ma microstrip circulators pakupanga tsogolo laukadaulo wa radar mosakayikira likhalabe lofunikira.
