Tekinoloje ya Anti-Jamming ya Antenna ndi Kugwiritsa Ntchito Zida Zapassive Microwave

Tekinoloje ya anti-jamming ya antenna imatanthawuza njira zingapo zomwe zimapangidwira kupondereza kapena kuthetsa kusokoneza kwa magetsi akunja (EMI) pakutumiza ndi kulandira ma siginecha, kuwonetsetsa kukhazikika ndi kudalirika kwa njira zoyankhulirana. Mfundo zazikuluzikulu ndikuphatikiza ma frequency-domain processing (mwachitsanzo, kudumphira pafupipafupi, kufalikira kwa sipekitiramu), kukonza malo (mwachitsanzo, kupanga beamform), ndi kukhathamiritsa kwa kamangidwe ka dera (mwachitsanzo, kufananiza kosokoneza). M'munsimu muli mwatsatanetsatane mwatsatanetsatane komanso kugwiritsa ntchito matekinolojewa.

paI. Antenna Anti-Jamming Technologiespa

pa1. Njira Zotsutsa-Domain Anti-Jamming Techniquespa

paFrequency Hopping (FHSS):Amasintha mwachangu ma frequency ogwiritsira ntchito (mwachitsanzo, masauzande pa sekondi iliyonse) kupewa zosokoneza, zomwe zimagwiritsidwa ntchito kwambiri pamalankhulidwe ankhondo ndi GPS.

paSpread Spectrum (DSSS/FHSS):Imakulitsa bandwidth yama siginecha pogwiritsa ntchito ma code a pseudo-random, kuchepetsa kachulukidwe wamagetsi ndikuwongolera kulolerana kosokoneza.

pa2. Njira Zotsutsana ndi Jamming Spatialpa

paMa Antennas Anzeru (Kusintha kwa Beamforming):Amapanga nulls munjira zosokoneza pomwe akukulitsa kulandirira kofunikira45. Mwachitsanzo, ma anti-jamming antennas a GPS amathandizira kuti malo azikhala okhazikika polandila ma frequency angapo komanso kuwunikira.

paKusefa kwa Polarization:Imalepheretsa kusokonezedwa pogwiritsa ntchito kusiyanasiyana kwa polarization, komwe kumagwiritsidwa ntchito kwambiri polumikizana ndi radar ndi satellite.

pa3.Njira Zotsutsana ndi Jamming za Circuit Levelpa

paMapangidwe Ochepa-Impedans:Imagwiritsira ntchito pafupi-zero-ohm impedance kupanga mayendedwe opapatiza kwambiri, kusefa kusokoneza opanda zingwe.

paAnti-Jamming Components (mwachitsanzo, Radisol):Imalepheretsa kulumikizana pakati pa tinyanga tating'ono tating'ono, ndikuwongolera magwiridwe antchito a radiation.

paII. Kugwiritsa ntchito kwa Passive Microwave Componentspa

Zida za ma microwave (zomwe zimagwira ntchito mu 4-86 GHz) zimagwira ntchito yofunika kwambiri pamakina odana ndi jamming antenna, kuphatikiza:

paMa Isolators & Circulatorpa

Zodzipatula zimalepheretsa kuwonetsa mphamvu kwa RF, kuteteza ma transmitters; ma circulator amathandizira mayendedwe azizindikiro, omwe amagwiritsidwa ntchito kwambiri pamakina ogawana ma transceiver.

paZigawo Zosefapa

Zosefera za bandpass/bandstop zimachotsa zosokoneza zakunja kwa gulu, monga kusefa mwanzeru mu anti-jamming GPS tinyanga 3.

paIII. Zochitika Zofananira za Ntchitopa

paNtchito Zankhondo:Ma radar onyamula mizinga amaphatikiza kudumpha pafupipafupi, kukonza polarization, ndi njira za MIMO kuti athane ndi zovuta zovuta.

paKulankhulana Kwachiwembu:Zida za Microwave/millimeter-wave passive zimathandizira kutumiza ma siginecha amphamvu kwambiri pamakina a 5G/6G.

Concept Microwave ndiwogulitsa padziko lonse lapansi zosefera makondam'mapulogalamu aMagalimoto apamlengalenga osayendetsedwa (ma UAV) ndi makina opangira ma UAV, kuphatikiza fyuluta ya lowpass, fyuluta ya highpass, notch/band stop fyuluta, fyuluta ya bandpass ndi mabanki osefera.
