Cov thev naus laus zis tiv thaiv kev cuam tshuam ntawm lub kav hlau txais xov tooj cua yog hais txog ntau yam txheej txheem uas tsim los tswj lossis tshem tawm qhov cuam tshuam ntawm kev cuam tshuam hluav taws xob sab nraud (EMI) rau kev xa thiab txais cov teeb liab ntawm lub kav hlau txais xov tooj cua, ua kom ntseeg tau tias muaj kev ruaj khov thiab kev ntseeg tau ntawm cov kab ke sib txuas lus. Cov ntsiab cai tseem ceeb suav nrog kev ua cov txheej txheem zaus-domain (piv txwv li, kev dhia zaus, kev nthuav dav spectrum), kev ua cov txheej txheem chaw (piv txwv li, beamforming), thiab kev tsim kho lub voj voog (piv txwv li, kev sib phim impedance). Hauv qab no yog kev faib tawm thiab kev siv cov thev naus laus zis no.
I. Cov Txuj Ci Antenna Anti-Jamming
1. Cov Txuj Ci Tiv Thaiv Kev Ua Txhaum Cai Zaus-Domain
Kev Hloov Zaus (FHSS):Hloov cov zaus ua haujlwm sai sai (piv txwv li, ntau txhiab zaus hauv ib ob) kom tsis txhob muaj cov kab cuam tshuam, uas feem ntau siv hauv kev sib txuas lus tub rog thiab GPS systems.
Kev Sib Kis Spectrum (DSSS/FHSS):Siv cov lej pseudo-random los nthuav cov teeb liab bandwidth, txo cov zog spectral density thiab txhim kho kev cuam tshuam.
2. Cov Txuj Ci Tiv Thaiv Kev Sib Tsoo Hauv Qhov Chaw
Cov Antennas Ntse (Adaptive Beamforming):Tsim cov nulls hauv cov kev taw qhia cuam tshuam thaum txhim kho qhov kev txais tos teeb liab xav tau 45. Piv txwv li, cov kav hlau txais xov GPS tiv thaiv kev cuam tshuam txhim kho qhov chaw ruaj khov los ntawm kev txais tos ntau zaus thiab beamforming.
Kev lim dej polarization:Txo kev cuam tshuam los ntawm kev siv qhov sib txawv ntawm polarization, uas siv dav hauv kev sib txuas lus radar thiab satellite.
3.Cov Txuj Ci Tiv Thaiv Kev Ua Txhaum Cai ntawm Circuit-Level
Tsim Qauv Qis-Impedance:Siv cov impedance ze-zero-ohm los tsim cov channel ultra-narrow, lim tawm cov kev cuam tshuam wireless sab nraud.
Cov Cheebtsam Tiv Thaiv Kev Txuas (piv txwv li, Radisol):Txo kev cuam tshuam ntawm kev sib txuas ntawm cov antennas uas nyob ze, txhim kho kev ua haujlwm ntawm lub zog hluav taws xob.
II. Cov Kev Siv ntawm Cov Cheebtsam Microwave Passive
Cov khoom siv microwave passive (ua haujlwm hauv 4–86 GHz) ua lub luag haujlwm tseem ceeb hauv cov kab ke tiv thaiv kev cuam tshuam ntawm antenna, suav nrog:
Cov Khoom Rho Tawm thiab Cov Khoom Siv Circulators
Cov khoom cais tawm tiv thaiv kev cuam tshuam ntawm lub zog RF, tiv thaiv cov transmitters; cov circulators ua rau muaj kev taw qhia ntawm lub teeb liab, feem ntau siv rau hauv cov kab ke antenna sib koom transceiver.
Cov Cheebtsam Lim
Cov lim dej Bandpass/bandstop tshem tawm cov kev cuam tshuam sab nraud, xws li kev lim dej ntse hauv cov kav hlau txais xov GPS tiv thaiv kev cuam tshuam.
III. Cov Xwm Txheej Siv Ib Txwm Muaj
Cov Ntawv Thov Tub Rog:Cov radars uas muaj foob pob hluav taws sib xyaw ua ke frequency hopping, polarization processing, thiab MIMO techniques los tawm tsam qhov nyuaj jamming.
Kev Sib Txuas Lus Hauv Pej Xeem:Cov khoom siv microwave/millimeter-wave passive ua rau muaj kev sib kis tau zoo hauv 5G/6G systems.
