Antenna Anti-Jamming Tekinoroji uye Kushandiswa kwePassive Microwave Zvikamu

Antenna anti-jamming tekinoroji inoreva nhevedzano yematekiniki akagadzirirwa kudzvanya kana kubvisa kukanganiswa kwekunze kwemagetsi emagetsi (EMI) pane antenna chiratidzo chekufambisa uye kugamuchira, kuve nechokwadi kugadzikana uye kuvimbika kwehurongwa hwekutaurirana. Misimboti yemisimboti inosanganisira frequency-domain processing (semuenzaniso, frequency hopping, spread spectrum), spatial processing (semuenzaniso, beamforming), uye wedunhu dhizaini optimization (semuenzaniso, impedance matching). Pazasi pane yakadzama kupatsanura uye mashandisirwo eaya matekinoroji.

.I. Antenna Anti-Jamming Technologies.

.1. Frequency-Domain Anti-Jamming Techniques.

.Frequency Hopping (FHSS):Kurumidza chinja mafambiro ekushanda (semuenzaniso, zviuru zvenguva pasekondi) kudzivirira mabhendi ekuvhiringa, anowanzo shandiswa mukutaurirana nemauto uye GPS masisitimu.

.Kupararira Spectrum (DSSS/FHSS):Inowedzera siginecha bandwidth uchishandisa pseudo-random macode, kuderedza simba spectral density uye kunatsiridza kukanganisa kushivirira.

.2. Spatial Anti-Jamming Techniques.

.Smart Antennas (Adaptive Beamforming):Inoumba nulls munzira dzekuvhiringidza uku ichiwedzera kugashira kwechiratidzo chaunoda45. Semuyenzaniso, anti-jamming GPS antennas inonatsiridza kugadzikana kwenzvimbo kuburikidza neakawanda-frequency kugashira uye beamforming.

.Polarization Sefa:Inodzvinyirira kupindira nekushandisa mutsauko wepolarization, unoshandiswa zvakanyanya muradar uye satellite kutaurirana.

.3.Circuit-Level Anti-Jamming Techniques.

.Yakaderera-Impedance Dhizaini:Inoshandisa pedyo-zero-ohm impedance kugadzira tambo dzakatetepa, kusefa kunze kwewireless kupindira.

.Anti-Jamming Zvikamu (semuenzaniso, Radisol):Inodzvanya kupindirana kwepakati pakati peantenna yakaganhurwa, inovandudza kugona kwemwaranzi.

.II. Zvishandiso zvePassive Microwave Zvikamu.

Passive microwave components (inoshanda mu4-86 GHz renji) inoita basa rakakosha muantenna anti-jamming system, kusanganisira:

.Isolators & Circulators.

Isolators inodzivirira RF simba rekuratidzira, inodzivirira transmitters; ma circulator anogonesa chiratidzo chekutungamira, chinowanzo shandiswa mu transceiver-yakagoverwa antenna masisitimu.

.Kusefa Zvikamu.

Bandpass/bandstop mafirita anobvisa kunze-kwe-bhendi kupindira, senge smart kusefa mune anti-jamming GPS antennas3.

.III. Mamiriro Ekushandisa Akajairika.

.Military Applications:Ma radar anotakurwa nema Missile anosanganisa frequency hopping, polarization process, uye MIMO matekiniki ekupikisa jamming yakaoma.

.Kukurukurirana Kwevanhu:Microwave/millimeter-wave passive components inogonesa yakakwirira-simba-renji chiratidzo chekufambisa mu5G/6G masisitimu.

Concept Microwave mutengesi wepasirese weakagadziridzwa mafiritamumashandisirwo eMota dzemuchadenga dzisina kufambiswa (UAVs) uye counter-UAV masisitimu, anosanganisira yakaderera sefa, highpass sefa, notch/band stop filter, bandpass filter uye mafirita mabhangi.
