He kuleana koʻikoʻi ke kamaʻilio Satellite i nā ʻoihana koa a me nā noi kīwila hou, akā ʻo kona hiki ke hoʻopilikia i ka hoʻomohala ʻana i nā ʻano hana anti-jamming. Hōʻuluʻulu kēia ʻatikala i nā ʻenehana ʻē aʻe ʻeono: pālahalaha spectrum, coding a modulation, antenna anti-jamming, on-board processing, transform-domain processing, a amplitude-domain processing, me nā ʻenehana loulou adaptive, ke kālailai ʻana i kā lākou mau loina a me nā noi.
1. Hoʻolaha ʻenehana Spectrum?
Hoʻonui ka Spread spectrum i ka mana anti-jamming ma ka hoʻonui ʻana i ka bandwidth hōʻailona, e hōʻemi ana i ka mana spectral density. Hoʻohana ʻo Direct Sequence Spread Spectrum (DSSS) i nā code pseudo-random e hoʻonui i ka bandwidth hōʻailona, e hoʻopuehu ana i ka ikehu hoʻopilikia. He mea koʻikoʻi kēia i nā kamaʻilio satelite pūʻali koa, ke kūʻē ʻana i ka hoʻopaʻapaʻa i manaʻo ʻia (e laʻa, co-frequency a i ʻole ka leo leo ākea) e hōʻoia i ke kauoha paʻa a me ka hoʻouna ʻike.
2. Hoʻopili a me Modulation Technology?
ʻO nā code hoʻoponopono hewa kiʻekiʻe (e laʻa, nā code Turbo, LDPC) i hui pū ʻia me ka modulation kiʻekiʻe (e laʻa, PSK, QAM) e hoʻomaikaʻi i ka pono spectral me ka hoʻēmi ʻana i nā hewa i hoʻopili ʻia. No ka laʻana, hoʻonui ka LDPC me ka QAM kauoha kiʻekiʻe i nā lawelawe ukali kalepa (e laʻa, HDTV, pūnaewele) a hōʻoia i ka kamaʻilio pūʻali koa ikaika i nā wahi hakakā.
3. Antenna Anti-Jamming Technology?
Hoʻololi ikaika nā antenna adaptive a me ka naʻauao i nā kumu kukuna e hoʻopau ai i nā jammers. Hoʻokele nā antenna adaptive i nā kumu hoʻopilikia, aʻo nā antenna akamai e hoʻohana i ka hana multi-array no ka kānana spatial. He mea koʻikoʻi kēia i ka SATCOM pūʻali e kūʻē i nā hoʻoweliweli kaua uila.
4. Mea Hana Hana Ma luna o ka Papa (OBP).?
Hana ʻo OBP i ka demodulation hōʻailona, decoding, a me ke ala pololei ʻana ma nā satelite, e hōʻemi ana i nā nāwaliwali o ka relay. Hoʻokomo ʻia nā noi koa i ka hana kūloko kūloko e pale i ka eavesdropping a me ka hoʻokaʻawale ʻana i nā kumuwaiwai no ka pono.
5. Transform-Domain Processing?
ʻO nā ʻenehana e like me FFT a me ka wavelet e hoʻololi i nā hōʻailona i ke alapine a i ʻole ka manawa-frequency domain no ke kānana hoʻopili. Hoʻopili kēia i ka broadband a me ka manawa-varying jamming, hoʻomaikaʻi i ka hoʻololi ʻana i nā kaiapuni electromagnetic paʻakikī.
6. Amplitude-Domain Processing?
Hoʻopaʻa ʻia nā palena a me ka Automatic Gain Control (AGC) i ke keakea ikaika (e laʻa, ka uila a i ʻole ka hoʻopaʻa ʻana o ka ʻenemi), pale i nā kaapuni mea hoʻokipa a mālama i ka paʻa o ka loulou.
7. Adaptive Link Technology?
ʻO ka hoʻololi ʻana i ka manawa maoli i ka coding, modulation, a me nā helu ʻikepili e pili ana i nā kūlana channel (e laʻa, SNR, BER) e hōʻoia i ka kamaʻilio kūpaʻa ʻoiai ʻo ka wā a i ʻole ka hoʻopaʻa ʻana. Hoʻohana nā ʻōnaehana koa i kēia no ke kūpaʻa ʻana i nā hiʻohiʻona kaua ikaika.
Ka hopena?
Hoʻohana nā ʻenehana anti-jamming ʻē aʻe i nā ʻano hoʻokalakupua he nui e pili ana i ka hoʻoili ʻana i nā hōʻailona, coding, a me nā ʻōnaehana adaptive. Hoʻohana mua ka hoʻohana kaua i ka ikaika a me ka palekana, ʻoiai nā noi pāʻoihana e kālele ana i ka pono. Hiki i nā holomua o ka wā e hiki mai ana ke hoʻohui iā AI a me ka hana manawa maoli e pale aku i nā hoʻoweliweli e ulu nei.
ʻO Chengdu Concept Microwave Technology CO., Ltd he mea hana ʻoihana o nā ʻāpana 5G/6G RF no ke kamaʻilio satellite ma Kina, me ka kānana haʻahaʻa haʻahaʻa RF, kānana kiʻekiʻe, kānana bandpass, kānana notch/band stop filter, duplexer, Power divider and directional coupler. Hiki ke hoʻopilikino ʻia lākou a pau e like me kāu requrements.
