Isishwankathelo soNxibelelwano lweSatellite yaNgaphandle kweAnti-Jamming Technologies

Unxibelelwano ngesathelayithi lunendima ebalulekileyo kwizicelo zale mihla zasemkhosini nezoluntu, kodwa ukuba sesichengeni sokuphazamiseka kuye kwaqhuba uphuhliso lweendlela ezahlukeneyo zokulwa nokuxinana. Eli nqaku lishwankathela ubuchwepheshe obuthandathu obuphambili bangaphandle: i-spectrum yokusabalalisa, ikhowudi kunye ne-modulation, i-antenna anti-jamming, i-on-board processing, i-transform-domain processing, kunye ne-amplitude-domain processing, kunye neendlela ezihambelanayo zekhonkco, ukuhlalutya imigaqo kunye nezicelo zabo.

1. Ukusasaza iTekhnoloji yeSpectrum...

I-spectrum yokusasaza iphakamisa amandla okuchasana ne-jamming ngokwandisa i-bandwidth yesignali, ukunciphisa ukuxinana kwamandla okubonakalayo. I-Spectrum ye-Direct Sequence Spread Spectrum (DSSS) isebenzisa iikhowudi ze-pseudo-random ukwandisa i-bandwidth yesignali, ukusabalalisa amandla okuphazamiseka kwe-narrowband. Oku kubalulekile kunxibelelwano lwesathelayithi yomkhosi, ukubala ukuxinana ngabom (umzekelo, i-co-frequency okanye ukuphazamisa ingxolo yebroadband) ukuqinisekisa umyalelo okhuselekileyo kunye nosasazo lobuntlola.

2. I-Coding kunye ne-Modulation Technology...

Iikhowudi eziphucukileyo zokulungisa iimpazamo (umzekelo, iikhowudi zeTurbo, iLDPC) ezidityaniswe nemodyuli ephezulu (umzekelo, i-PSK, i-QAM) iphucula ukusebenza kakuhle kwembonakalo ngelixa unciphisa iimpazamo ezibangelwa kukuphazanyiswa. Umzekelo, i-LDPC ene-QAM ephezulu iphucula iinkonzo zesathelayithi zorhwebo (umzekelo, i-HDTV, i-intanethi) kwaye iqinisekisa unxibelelwano lomkhosi olomeleleyo kwiindawo ezikhuphisanayo.

3. I-Antenna Anti-Jamming Technology...

Ii-eriyali eziguquguqukayo kunye nezikrelekrele zihlengahlengisa iipateni zemiqadi ukuze zitshitshise iijammers. Ii-eriyali eziguquguqukayo zilawula ama-nulls ukuya kwimithombo yophazamiseko, ngelixa ii-eriyali ezikrelekrele zisebenzisa inkqubo yoluhlu oluninzi lokucoca indawo. Ezi zibalulekile kwiSATCOM yomkhosi ukulwa izoyikiso zemfazwe ye-elektroniki.

4. ITekhnoloji ye-On-Board Processing (OBP)....

I-OBP yenza ukuthotywa komqondiso, ukucacisa, kunye nokuhamba ngokuthe ngqo kwiisathelayithi, ukunciphisa ubuthathaka bokuhanjiswa komhlaba. Izicelo zomkhosi zibandakanya ukusetyenzwa kwasekhaya okukhuselekileyo ukuthintela ukuvalelwa kunye nokwabiwa kwezixhobo zokusebenza kakuhle.

5. Ukuguqulwa kweDomain Processing...

Ubuchwephesha obufana ne-FFT kunye ne-wavelet iguqula imiqondiso ukuba ibe ngamaxesha okanye imimandla yexesha eliqhelekileyo lokucoca ukuphazamisa. Oku kulwa ne-broadband kunye ne-jamming eguquguqukayo yexesha, ukuphucula ukuguquguquka kwimeko enzima ye-electromagnetic.

6. I-Amplitude-Domain Processing...

Imida kunye noLawulo lokuNgena ngokuzenzekelayo (AGC) lucinezela uphazamiseko olungxamisekileyo olunamandla (umzekelo, umbane okanye ukuxinana kotshaba), ukukhusela iisekethe zomamkeli kunye nokugcina uzinzo lwekhonkco.

7. I-Adaptive Link Technology...

Ulungelelwaniso lwexesha langempela kwikhowudi, ukumodareyitha, kunye namazinga edatha ngokusekelwe kwiimeko zetshaneli (umzekelo, i-SNR, i-BER) iqinisekisa unxibelelwano oluthembekileyo nangona imozulu okanye i-jamming. Iinkqubo zomkhosi ziphakamisa oku ukomelela kwiimeko zemfazwe.

Ukuqukumbela...

Ubuchwephesha bokuchasana ne-jamming bangaphandle busebenzisa iindlela ezinolwaleko oluninzi ezithatha ukusetyenzwa komqondiso, ukukhowudwa, kunye neenkqubo eziguqukayo. Ukusetyenziswa komkhosi kubeka phambili ukuqina kunye nokhuseleko, ngelixa izicelo zorhwebo zijolise ekusebenzeni kakuhle. Inkqubela phambili yexesha elizayo inokudibanisa i-AI kunye nokusetyenzwa kwexesha lokwenyani ukulwa nezoyikiso ezivelayo.
