Butler matrix yog ib hom kev siv beamforming network siv nyob rau hauv kav hlau txais xov arrays thiab phased array systems.Nws lub luag haujlwm tseem ceeb yog:
● Beam steering - Nws tuaj yeem coj tus kav hlau txais xov kab mus rau qhov sib txawv los ntawm kev hloov qhov chaw nres nkoj nkag.Qhov no tso cai rau lub kav hlau txais xov rau hluav taws xob luam theej duab nws cov nqaj yam tsis muaj lub cev txav lub kav hlau txais xov.
● Multi-beam tsim - Nws tuaj yeem pub lub kav hlau txais xov array nyob rau hauv ib txoj kev uas tsim ntau kab teeb ib txhij, txhua taw tes rau hauv ib qho kev taw qhia sib txawv.Qhov no ua rau kom cov kev pab cuam thiab rhiab heev.
● Beam splitting – Nws faib cov teeb liab tawm tswv yim rau hauv ntau qhov chaw tso zis nrog rau cov theem kev sib raug zoo.Qhov no ua rau cov kav hlau txais xov txuas txuas rau tsim cov kab lus qhia.
● Beam combining – Lub reciprocal muaj nuj nqi ntawm beam splitting.Nws muab cov teeb liab los ntawm ntau lub kav hlau txais xov rau hauv ib qho kev tso zis nrog kev nce siab dua.
Butler matrix ua tiav cov haujlwm no los ntawm nws cov qauv ntawm hybrid couplers thiab taag theem shifters teem nyob rau hauv ib tug matrix layout.Qee cov khoom tseem ceeb:
● Cov theem hloov ntawm qhov chaw tso zis uas nyob ib sab feem ntau yog 90 degrees (ib lub quarter wavelength).
● Tus naj npawb ntawm kab teeb yog txwv los ntawm tus naj npawb ntawm cov chaw nres nkoj (N x N Butler matrix tsim N beams).
● Beam cov lus qhia yog txiav txim los ntawm matrix geometry thiab phasing.
● Kev poob qis, tsis muaj zog, thiab kev ua haujlwm sib luag.
Yog li hauv cov ntsiab lus, lub luag haujlwm tseem ceeb ntawm Butler matrix yog pub tus kav hlau txais xov array nyob rau hauv ib txoj kev uas tso cai rau dynamic beamforming, beam steering, thiab multi-beam muaj peev xwm los ntawm hluav taws xob tswj tsis muaj qhov txav.Nws yog ib qho kev siv thev naus laus zis rau electronically scanned arrays thiab phased array radars.
Tswvyim Microwave yog ib lub chaw muag khoom thoob ntiaj teb ntawm lub tshuab hluav taws xob matrix, txhawb nqa multichannel MIMO kuaj txog li 8 + 8 kav hlau txais xov chaw nres nkoj, hla ntau zaus.
