Emhlabeni wobuchwepheshe be-radar, ukuthuthukiswa kwamasistimu we-radar yezigaba ezihlukene kuguqule indlela esithola ngayo kanye nesilandelela ngayo izinto ezisesibhakabhakeni. Lawa masistimu anikeza ukuguquguquka okuthuthukisiwe, ukusebenza okuthuthukisiwe, namandla athuthukisiwe uma kuqhathaniswa namasistimu e-radar evamile. Ingxenye ebalulekile ebambe iqhaza ekuthuthukisweni kobuchwepheshe be-radar yezigaba ezihlukene i-microstrip circulator.
Amasistimu e-radar ahlelwe ngezigaba asebenzisa izimpondo eziningi ukudlulisa nokwamukela amasiginali wefrikhwensi yomsakazo. Lawa ma-antenna ahlelwe ngohlelo lokucushwa olunezigaba, okuvumela isiteringi se-electronic beamforming. Lokhu kuvumela isistimu ye-radar ukuthi ihlole ngokushesha indawo yomoya ezungezile, ilandele okuqondiwe okuningi ngesikhathi esisodwa, futhi ivumelane nezimfuneko zokusebenza ezishintshayo.
I-microstrip circulator iyisakhi esibalulekile ngaphakathi kwesistimu ye-radar yohlu oluhlukaniswe ngezigaba. Kuyidivayisi engenzi lutho, engahoshelani evumela umzila ophumelelayo wamasignali e-RF ngaphakathi kwesistimu ye-radar. I-circulator iqinisekisa ukuthi amasignali adlulisiwe aqondiswe ezintini ukuze zidluliselwe nokuthi amasignali atholiwe adluliselwa kumamukeli ukuze acutshungulwe. Lokhu kusebenza kubalulekile ekugcineni ubuqotho bokusebenza kwesistimu ye-radar nokukhulisa ukusebenza kwayo.
Enye yezinzuzo ezibalulekile zokusebenzisa ama-microstrip circulator kumasistimu e-radar ahlukahlukene usayizi wawo ohlangene nesisindo esiphansi. Ama-circulator endabuko makhulu futhi asindayo, okuwenza angakufanelekeli ukuhlanganiswa kumasistimu e-radar esimanje abeka phambili ukuphatheka nokuhamba. Ama-Microstrip circulators, ngakolunye uhlangothi, aklanyelwe ukuba angasindi futhi aminyene, awenze alungele ukusetshenziswa ezinhlelweni ze-radar ezihlukaniswe ngezigaba ezisatshalaliswa kumapulatifomu eselula njengezindiza, imikhumbi, nezimoto eziphansi.
Ngaphezu kwalokho, ama-microstrip circulators anikeza izici zokusebenza ezinhle kakhulu, okuhlanganisa ukulahleka kokufakwa okuphansi, ukuhlukaniswa okuphezulu, kanye nomkhawulokudonsa obanzi. Lezi zimfanelo zibalulekile ekuqinisekiseni ukudluliswa nokwamukelwa kahle kwamasiginali e-RF ngaphakathi kwesistimu ye-radar. Ukulahlekelwa kokufakwa okuphansi kunciphisa ukulahleka kwamandla esignali njengoba edlula kusizungeza, kuyilapho ukuhlukaniswa okuphezulu kuvimbela ukuvuza kwesignali okungafunwa, okuqinisekisa ubuqotho bokusebenza kwesistimu ye-radar. Ukwengeza, amandla omkhawulokudonsa obanzi avumela isistimu ye-radar ukuthi isebenze kububanzi obubanzi befrikhwensi, iyenze ibe nezinto ezihlukahlukene futhi ivumelane nezimo ezihlukahlukene zokusebenza.
Ukuhlanganiswa kwama-microstrip circulator kumasistimu e-radar ahlukahlukene kuye kwanikela ekuthuthukisweni kobuchwepheshe be-radar, okuvumela amakhono athuthukisiwe njengempi ye-electronic, ukuhlonza okuhlosiwe, kanye nokunemba kokulandelela. Imvelo engashintshile ye-circulator ivumela ukuqaliswa kwamasu okucutshungulwa kwesignali athuthukisiwe, njenge-frequency agility kanye nokuhlukahluka kwe-polarization, okubalulekile kumasistimu e-radar yesimanje ukuze abhekane nezinyathelo eziphikisana ne-elekthronikhi futhi alondoloze ukusebenza kahle kokusebenza ezindaweni eziyinkimbinkimbi ze-electromagnetic.
Sengiphetha, ukufakwa kwama-microstrip circulator kumasistimu e-radar ahlukahlukene kuthuthukise kakhulu amandla nokusebenza kobuchwepheshe be-radar. Lawa madivayisi ahlangene, angasindi, futhi asebenza kahle anikeze amandla ukuthuthukiswa kwamasistimu e-radar ayinkimbinkimbi anikeza ukuguquguquka okuthuthukisiwe, ukusebenza kahle okuthuthukisiwe, namandla okulandelela okuqondiwe aphakeme. Njengoba isidingo samasistimu e-radar athuthukile siqhubeka sikhula, indima yama-microstrip circulator ekulolongeni ikusasa lobuchwepheshe be-radar ngokungangabazeki izohlala ibalulekile.
