Nyob rau hauv lub ntiaj teb no ntawm radar technology, txoj kev loj hlob ntawm phased array radar systems tau revolutionized txoj kev peb ntes thiab taug qab cov khoom nyob rau hauv lub ntuj. Cov tshuab no muaj kev ua kom yooj yim dua, txhim kho kev ua tau zoo, thiab muaj peev xwm ua kom zoo dua qub piv rau cov tshuab radar. Ib qho tseem ceeb tivthaiv uas tau pab txhawb rau kev nce qib ntawm phased array radar technology yog microstrip circulator.
Phased array radar systems siv ntau lub kav hlau txais xov kom xa thiab tau txais xov tooj cua zaus teeb liab. Cov kav hlau txais xov no tau teem rau hauv ib qho kev teeb tsa theem, tso cai rau hluav taws xob beam steering thiab beamforming. Qhov no ua rau lub radar system tuaj yeem tshawb xyuas lub dav hlau nyob ib puag ncig, taug qab ntau lub hom phiaj ib txhij, thiab hloov mus rau kev hloov pauv kev ua haujlwm.
Lub microstrip circulator yog ib qho tseem ceeb nyob rau hauv lub phased array radar system. Nws yog ib tug passive, uas tsis yog-reciprocal ntaus ntawv uas tso cai rau lub routing npaum RF signals nyob rau hauv lub radar system. Lub circulator xyuas kom meej tias cov teeb liab kis tau raug xa mus rau lub kav hlau txais xov rau kev sib kis thiab tias cov teeb liab tau txais raug xa mus rau lub receiver rau kev ua haujlwm. Qhov kev ua haujlwm no yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm radar system kev ua haujlwm thiab ua kom nws ua tau zoo tshaj plaws.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv microstrip circulators hauv phased array radar systems yog lawv qhov loj me thiab qhov hnyav. Cov circulators ib txwm muaj hnyav thiab hnyav, ua rau lawv tsis tsim nyog rau kev sib koom ua ke rau niaj hnub radar systems uas tseem ceeb rau kev txav mus los thiab kev txav mus los. Microstrip circulators, ntawm qhov tod tes, yog tsim los ua lub teeb yuag thiab compact, ua rau lawv zoo tagnrho rau siv nyob rau hauv phased array radar systems deployed rau mobile platforms xws li aircraft, ships, thiab av tsheb.
Tsis tas li ntawd, microstrip circulators muaj cov yam ntxwv ua tau zoo, suav nrog kev tso qis qis, kev sib cais siab, thiab dav bandwidth. Cov cwj pwm no yog qhov tseem ceeb rau kev ua kom muaj kev sib kis tau zoo thiab txais cov cim RF hauv lub radar system. Qhov poob qis qis txo qis cov teeb liab poob qis thaum nws dhau los ntawm lub tshuab hluav taws xob, thaum qhov kev sib cais siab tiv thaiv cov teeb liab tsis xav tau, ua kom muaj kev ncaj ncees ntawm radar system kev ua haujlwm. Tsis tas li ntawd, qhov dav bandwidth muaj peev xwm tso cai rau lub radar system ua haujlwm thoob plaws ntau qhov ntau zaus, ua rau nws muaj ntau yam thiab hloov tau rau ntau yam kev ua haujlwm.
Kev sib koom ua ke ntawm microstrip circulators rau hauv theem array radar systems kuj tau pab txhawb kev nce qib hauv radar thev naus laus zis, ua kom muaj peev xwm txhim kho xws li hluav taws xob ua tsov rog, kev txheeb xyuas lub hom phiaj, thiab kev taug qab qhov tseeb. Cov xwm txheej tsis sib xws ntawm lub voj voog tso cai rau kev siv cov txheej txheem ua haujlwm siab tshaj plaws, xws li kev nrawm nrawm thiab kev sib txawv ntawm polarization, uas yog qhov tseem ceeb rau cov tshuab radar niaj hnub los tiv thaiv hluav taws xob tiv thaiv thiab tswj kev ua haujlwm zoo hauv thaj chaw electromagnetic complex.
Hauv kev xaus, kev koom ua ke ntawm microstrip circulators rau hauv theem array radar systems tau ua kom muaj peev xwm thiab kev ua tau zoo ntawm radar thev naus laus zis. Cov khoom siv compact, lub teeb yuag, thiab kev ua haujlwm siab tau ua rau kev txhim kho cov txheej txheem radar uas muaj kev hloov pauv tau yooj yim, txhim kho kev ua haujlwm tau zoo, thiab muaj peev xwm taug qab tau zoo dua. Raws li qhov kev thov rau cov tshuab radar qib siab txuas ntxiv mus ntxiv, lub luag haujlwm ntawm microstrip circulators hauv kev txhim kho lub neej yav tom ntej ntawm radar thev naus laus zis yuav tsis muaj qhov xav tau tseem ceeb.
