Kuyankhulana kwa satellite kumagwira ntchito yofunika kwambiri pazochitika zamakono zankhondo ndi anthu wamba, koma kusokonezeka kwake kwachititsa kuti pakhale njira zosiyanasiyana zotsutsana ndi jamming. Nkhaniyi ikufotokoza mwachidule matekinoloje asanu ndi limodzi ofunika kwambiri akunja: kufalitsa spectrum, coding and modulation, antenna anti-jamming, on-board processing, transform-domain processing, and amplitude-domain processing, pamodzi ndi njira zogwirizanitsa zogwirizanitsa, kusanthula mfundo zawo ndi ntchito.
1. Kufalitsa Spectrum Technologypa
Kufalikira kwa sipekitiramu kumakulitsa luso lodana ndi jamming mwa kukulitsa bandwidth yama siginecha, kuchepetsa kachulukidwe wamagetsi. Direct Sequence Spread Spectrum (DSSS) imagwiritsa ntchito ma pseudo-random codes kukulitsa bandwidth ya siginecha, kubalalitsa mphamvu yosokoneza ya narrowband. Izi ndizofunikira kwambiri pamalankhulidwe a satana ankhondo, kutsutsa kuthamangitsana mwadala (mwachitsanzo, kusokoneza kwapafupipafupi kapena kusokoneza phokoso la Broadband) kuwonetsetsa kutetezedwa kotetezedwa ndi kufalitsa nzeru.
2. Coding ndi Modulation Technologypa
Ma code owongolera zolakwika (monga ma Turbo codes, LDPC) ophatikizidwa ndi kusinthidwa kwadongosolo lapamwamba (mwachitsanzo, PSK, QAM) amawongolera magwiridwe antchito ndikuchepetsa zolakwika zosokoneza. Mwachitsanzo, LDPC yokhala ndi dongosolo lapamwamba la QAM imakulitsa ntchito za satellite zamalonda (mwachitsanzo, HDTV, intaneti) ndikuwonetsetsa kulumikizana kwamphamvu kwankhondo m'malo omwe amapikisana nawo.
3. Antenna Anti-Jamming Technologypa
Tinyanga zosinthika komanso zanzeru zimasintha masinthidwe amtengo kuti athetse ma jammers. Tinyanga zosinthika zimatsogolera kuzinthu zosokoneza, pomwe tinyanga tanzeru timagwiritsa ntchito njira zingapo zosefera. Izi ndizofunikira mu SATCOM yankhondo kuti athane ndi ziwopsezo zankhondo zamagetsi.
4. Ukadaulo wa Pa board (OBP) Technologypa
OBP imapanga ma signature, decoding, and routing molunjika pa satellite, kuchepetsa chiwopsezo cha relay. Ntchito zankhondo zimaphatikizapo kukonza kotetezedwa kwanuko kuti mupewe kumvetsera komanso kugawa bwino zida kuti zitheke.
5. Kusintha-Domain Processingpa
Njira ngati FFT ndi wavelet amasintha ma siginecha kukhala ma frequency kapena madera anthawi zosefera. Izi zimalimbana ndi kuchuluka kwa ma Broadband ndi kusinthasintha kwa nthawi, kuwongolera kusinthika m'malo ovuta amagetsi.
6. Amplitude-Domain Processingpa
Malire ndi Automatic Gain Control (AGC) amapondereza kusokoneza kwamphamvu mopupuluma (mwachitsanzo, mphezi kapena kupindika kwa adani), kuteteza mabwalo olandila ndikusunga ulalo kukhazikika.
7. Adaptive Link Technologypa
Kusintha kwanthawi yeniyeni pamakhodi, kusinthasintha, ndi mitengo ya data kutengera momwe ma tchanelo alili (monga, SNR, BER) zimatsimikizira kulumikizana kodalirika ngakhale kuti kuli nyengo kapena kusanja. Asilikali amathandizira izi kuti athe kupirira pazochitika zankhondo.
Mapetopa
Matekinoloje odana ndi jamming akunja amagwiritsa ntchito njira zingapo zosinthira ma sigino, kukopera, ndi makina osinthira. Kugwiritsa ntchito usilikali kumaika patsogolo kulimba ndi chitetezo, pamene ntchito zamalonda zimayang'ana kwambiri pakuchita bwino. Kupita patsogolo kwamtsogolo kungaphatikizepo AI ndi kukonza nthawi yeniyeni kuti athane ndi zowopseza zomwe zikuchitika.
Chengdu Concept Microwave Technology CO., Ltd ndi katswiri wopanga zida za 5G/6G RF zolumikizirana ndi satellite ku China, kuphatikiza fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop, duplexer, Power divider ndi coupler yolunjika. Zonse zitha kusinthidwa malinga ndi zomwe mukufuna.
