Isgaadhsiinta dayax-gacmeedku waxa ay door muhiim ah ka ciyaartaa militariga casriga ah iyo codsiyada rayidka, laakiin u nuglaanshaha faragelinta ayaa horseeday horumarinta farsamooyin kala duwan oo ka hortag ah. Maqaalkani waxa uu soo koobayaa lix teknoolajiyada ajnabiga ah ee muhiimka ah: faafinta spectrum, codeing iyo modulation, anteenada anti-jamming, processing on-board, transform-domain processing, iyo amplitude-domain processing, oo ay la socdaan farsamooyinka isku xirka la qabsiga, falanqaynta mabaadi'dooda iyo codsiyadooda.
1. Faafidda tignoolajiyada Spectrum?
Faafinta spectrum waxay xoojisaa awooda ka-hortagga jammaynta iyadoo la balaadhinayo xadhkaha xadhkaha goosashada, yaraynta cufnaanta muuqaalka awoodda. Direct Sequence Spread Spectrum (DSSS) waxay adeegsataa koodh random-ka- random ah si ay u balaariso xadhkaha xadhkaha goosha, kala firdhisa tamarta dhex dhexaadinta xadhiga cidhiidhiga ah. Tani waxay muhiim u tahay isgaarsiinta dayax-gacmeedka militariga, kahortaga isku-dhafka ula kac ah (tusaale, faragelinta buuqa iyo buuqa ballaaran) si loo xaqiijiyo gudbinta taliska iyo sirdoonka sugan.
2. Tignoolajiyada Codaynta iyo Habaynta?
Koodhadhka hagaajinta sare ee khaladaadka (tusaale, Turbo codes, LDPC) oo ay weheliyaan habaynta nidaamka sare (tusaale, PSK, QAM) waxay hagaajiyaan hufnaanta muuqaalka iyadoo la yareynayo khaladaadka faragelinta. Tusaale ahaan, LDPC oo leh QAM-sarreeya waxay xoojisaa adeegyada dayax-gacmeedka ganacsiga (tusaale, HDTV, internet) waxayna xaqiijisaa wada-gaarsiinta millatari ee adag ee goobaha lagu muransan yahay.
3. Tignoolajiyada Anti-Jamming Anteenada?
Anteenooyinka la qabsiga iyo kuwa caqliga leh ayaa si firfircoon u hagaajiya qaababka iftiinka si ay u baabi'iyaan jammers. Anteenooyinka la qabsiga ah waxay u leexiyaan ilaha faragelinta, halka anteenooyinka caqliga leh ay u isticmaalaan nidaaminta habab badan si ay u shaandheeyaan goobta. Kuwani waxay muhiim u yihiin militariga SATCOM si ay uga hortagaan hanjabaadaha dagaalka elektiroonigga ah.
4. Tiknoolajiyada Hagaajinta Boodhka (OBP).?
OBP waxa ay qabataa habaynta signalada, goynta, iyo habaynta tooska ah ee satalaytka, iyada oo yaraynaysa dayacanka isu gudbinta dhulka. Codsiyada militariga waxaa ka mid ah habayn sugan oo maxalli ah si looga hortago dhageysiga iyo qoondaynta kheyraadka ee la wanaajiyey.
5. Badal-Domain Processing?
Farsamooyinka sida FFT iyo mawjaduhu waxay u beddelaan calaamadaha soo noqnoqda ama waqtiyada soo noqnoqda ee shaandhaynta faragelinta. Tani waxay la dagaallantaa xayndaabyada ballaaran iyo waqti-kala-duwanaanta, hagaajinta la qabsiga jawiga korantada ee adag.
6. Balaadhan-Domain Processing?
Xaddidaadaha iyo Xakamaynta Faa'iidada Tooska ah (AGC) waxay xakameeyaan faragelinta xooggan ee degdega ah (tusaale, hillaaca ama isku-xidhka cadawga), ilaalinta wareegyada qaataha iyo ilaalinta xasilloonida isku xidhka.
7. Tignoolajiyada La Qabsiga?
Dib-u-habaynta wakhtiga-dhabta ah ee codaynta, habaynta, iyo heerka xogta ee ku salaysan xaaladaha kanaalka (tusaale, SNR, BER) waxay xaqiijisaa wada xidhiidhka la isku halayn karo inkasta oo cimilo ama cidhiidhi. Nidaamyada militariga ayaa tan uga faa'iideysta u adkeysiga xaaladaha dagaalka firfircoon.
Gabagabo?
Tignoolajiyada qalaad ee ka-hortagga-jamming-ka waxay shaqaaleeyaan habab badan oo lakabyo leh oo ku saabsan hab-samaynta calaamadaha, codaynta, iyo nidaamyada la-qabsiga. Isticmaalka ciidanku waxa uu mudnaan siinayaa adkaynta iyo amniga, halka codsiyada ganacsigu ay diiradda saaraan hufnaanta. Horumarka mustaqbalka ayaa laga yaabaa inuu isku daro AI iyo habaynta waqtiga-dhabta ah si looga hortago khataraha soo koraya.
