Kwihlabathi letekhnoloji yeradar, uphuhliso lweenkqubo zeradar ezicwangcisiweyo ziye zayiguqula indlela esibhaqa ngayo kunye nokulandelela izinto esibhakabhakeni. Ezi nkqubo zibonelela ngokuguquguquka okwandisiweyo, ukusebenza okuphuculweyo, kunye nesakhono esiphuculweyo xa kuthelekiswa neenkqubo zerada zemveli. Elinye icandelo eliphambili elibe negalelo kuphuhliso lwetekhnoloji ye-radar enezigaba yi-microstrip circulator.
Iinkqubo zoluhlu lwerada olunezigaba zisebenzisa ii-eriyali ezininzi ukusasaza nokufumana imiqondiso yamaza kanomathotholo. Ezi-eriyali zicwangciswe ngokucwangciswa koluhlu olunezigaba, oluvumela ukuba kubekho i-electronic beam steering kunye ne-beamforming. Oku kwenza ukuba inkqubo ye-radar ihlole ngokukhawuleza indawo yomoya ejikelezileyo, ilandele iithagethi ezininzi ngaxeshanye, kwaye iqhelane nokutshintsha kweemfuno zokusebenza.
I-microstrip circulator licandelo elibalulekileyo ngaphakathi kwenkqubo ye-radar yoluhlu lwezigaba. Sisixhobo esingenzi nto, esingabuyiselaniyo esivumela ukuhanjiswa ngendlela esebenzayo kweempawu zeRF ngaphakathi kwenkqubo yerada. Isetyhula iqinisekisa ukuba imiqondiso ethunyelwayo ibhekiswa kwii-eriyali ukuze idluliselwe kwaye imiqondiso efunyenweyo ithunyelwa kummkeli ukuze iqwalaselwe. Oku kusebenza kubalulekile ekugcineni intembeko yokusebenza kwenkqubo ye-radar kunye nokwandisa ukusebenza kwayo.
Enye yeengenelo eziphambili zokusebenzisa ii-microstrip circulators kwiinkqubo ze-radar ze-radar zibubungakanani bazo obuncinci kunye nobunzima obuphantsi. Ii-circulators zendabuko zinkulu kwaye zinzima, zibenza bangafaneleki ukuhlanganiswa kwiinkqubo ze-radar zanamhlanje ezibeka phambili ukuthwala kunye nokuhamba. I-Microstrip circulators, ngakolunye uhlangothi, yenzelwe ukuba ibe yi-lightweight kunye ne-compact, iyenze ibe yinto efanelekileyo yokusetyenziswa kwiinkqubo ze-radar ezifakwe kwi-mobile platforms ezifana neenqwelo-moya, iinqanawa kunye nezithuthi zomhlaba.
Ngapha koko, ii-microstrip circulators zibonelela ngeempawu ezibalaseleyo zokusebenza, kubandakanya ilahleko ephantsi yokufaka, ukubekwa wedwa okuphezulu, kunye ne-bandwidth ebanzi. Ezi mpawu zibalulekile ekuqinisekiseni ugqithiso olululo kunye nolwamkelo lwemiqondiso yeRF ngaphakathi kwenkqubo yerada. Ilahleko ephantsi yokufakela inciphisa ukulahleka kwamandla omqondiso njengoko idlula kwisetyhula, ngelixa ukubekelwa bucala okuphezulu kuthintela ukuvuza komqondiso okungafunwayo, kuqinisekisa ukuthembeka komsebenzi wenkqubo ye-radar. Ukongeza, amandla obubanzi obubanzi buvumela inkqubo ye-radar ukuba isebenze kuluhlu olubanzi lwee-frequencies, iyenze ibe yinto eguquguqukayo kwaye ivumelane neemeko ezahlukeneyo zokusebenza.
Ukudityaniswa kwee-microstrip circulators kwiinkqubo zoluhlu lweradar eziye zanegalelo kwinkqubela phambili yobuchwepheshe berada, okwenza ukuba amandla aphuculweyo afana nemfazwe yombane, ukuchongwa kwethagethi, kunye nokuchaneka kokulandela umkhondo. Ubume obungatshintshiyo be-circulator buvumela ukuphunyezwa kweendlela eziphambili zokucwangcisa umqondiso, ezifana ne-frequency agility kunye ne-polarization diversity, eziyimfuneko kwiinkqubo ze-radar zanamhlanje ukuchasana nemilinganiselo yombane kunye nokugcina ukusebenza okusebenzayo kwiindawo ezinzima ze-electromagnetic.
Ukuqukumbela, ukudityaniswa kwee-microstrip circulators kwiinkqubo ze-radar ezinezigaba kuye kwaphucula kakhulu amandla kunye nokusebenza kobuchwephesha be-radar. Ezi zixhobo zihlangeneyo, zikhaphukhaphu, kunye nokusebenza okuphezulu kwenze ukuba kuphuhliswe iinkqubo zeradar eziphucukileyo ezibonelela ngokuguquguquka okuphuculweyo, ukuphuculwa kokusebenza okusebenzayo, kunye nobuchule obuphezulu bokulandela umkhondo. Njengoko imfuno yeenkqubo eziphambili zeradar iqhubeka ikhula, indima yee-microstrip circulators ekubumbeni ikamva lobuchwephesha beradar ngokungathandabuzekiyo iya kuhlala ibalulekile.
