Tekinoroji yekudzivirira jamming yeAntenna inoreva nzira dzakasiyana-siyana dzakagadzirirwa kudzvinyirira kana kubvisa kukanganisa kwekunze kwemagetsi (EMI) pakutumira nekugamuchira masaini eantenna, zvichiita kuti masisitimu ekutaurirana ave akasimba uye akavimbika. Nheyo huru dzinosanganisira kugadzirisa mafrequency-domain (semuenzaniso, frequency hopping, spread spectrum), spatial processing (semuenzaniso, beamforming), uye circuit design optimization (semuenzaniso, impedance matching). Pazasi pane kupatsanurwa kwakadzama uye mashandisirwo ematekinoroji aya.
I. Matekinoroji eAnti-Jamming eAntenna
1. Maitiro Ekudzivirira Kujairika KwemaDomain
Kusvetuka-svetuka kakawanda (FHSS):Inochinja mafrequency ekushanda nekukurumidza (semuenzaniso, zviuru zvenguva pasekondi) kudzivirira kupindirana kwemabhendi, anoshandiswa zvakanyanya mukukurukurirana kwemauto uye masisitimu eGPS.
Spectrum yeKupararira (DSSS/FHSS):Inowedzera bandwidth yechiratidzo uchishandisa makodhi epseudo-random, ichideredza huwandu hwesimba respectral uye inovandudza kushivirira kwekupindira.
2. Maitiro Ekudzivirira Kupwanya Nzvimbo
MaAntenna Akangwara (Anochinjika Beamforming):Inoita kuti nzira dzekupindira dzisashande zvakanaka uku ichivandudza kugamuchira kwechiratidzo kwaunoda45. Semuenzaniso, maantenna eGPS anodzivirira kuvharika anovandudza kugadzikana kwenzvimbo kuburikidza nekugamuchira mafrequency akawanda uye kugadzira beamforming.
Kusefa kwePolarization:Inodzivirira kupindira nekushandisa musiyano we polarization, unoshandiswa zvakanyanya mukukurukurirana kwe radar ne satellite.
3.Maitiro Ekudzivirira Kuvharika Kwedenderedzwa
Dhizaini Yekupomba Zvisina Kusimba:Inoshandisa near-zero-ohm impedance kugadzira nzira dzakatetepa kwazvo, ichisefa kupindira kwekunze kwewaya isina waya.
Zvikamu Zvinorwisa Kujamming (semuenzaniso, Radisol):Inoderedza kupindirana kwekubatanidza pakati pemaantenna ari pedyo, zvichivandudza kushanda zvakanaka kwemwaranzi.
II. Mashandisirwo eZvikamu zveMaikorowevhi Zvisingashandiswi
Zvikamu zve microwave zvisingashande (zvinoshanda mu 4–86 GHz range) zvine basa rakakosha mu antenna anti-jamming systems, zvinosanganisira:
Zvinobvisa Madhiraivha & Zvinotenderera
Zvinobvisa ma RF energy reflection zvinodzivirira ma transmitter; ma circulator anogonesa kutungamira kwesignal, iyo inowanzoshandiswa muma transceiver-shared antenna systems.
Zvikamu Zvekusefa
Mafirita ebhendi/bhendi anobvisa kupindira kwekunze kwebhendi, senge kufirita kwakangwara mumagetsi eGPS anodzivirira kuvharika kwejamming3.
III. Maitiro Akajairika Ekushandisa
Zvikumbiro zvemauto:Maradar anotakurwa nezvombo zvinokandwa anosanganisa frequency hopping, polarization processing, uye MIMO techniques kudzivirira complex jamming.
Kutaurirana Kwevanhu Veruzhinji:Zvikamu zve microwave/millimeter-wave passive zvinogonesa kutumira masaini emhando yepamusoro-soro mu 5G/6G systems.
Concept Microwave inopa mafirita akagadzirwa nevanhu pasi rosemukushandiswa kweMota dzisina mutyairi (UAVs) uye masisitimu ekudzivirira mavhiri, kusanganisira firita repasi pasi, firita repasi pasi, firita renotch/band stop, firita repasi pasi uye firita.
