Kukurukurirana nesatellite kunobata basa rakakosha mukushandiswa kwechiuto uye kwevanhuwo zvavo kwemazuva ano, asi kukanganisa kwayo kupindira kwakafambisa kuvandudzwa kwemaitiro akasiyana-siyana ekurwisa jamming. Ichi chinyorwa chinopfupisa matanhatu akakosha matekinoroji ekunze: kuparadzira spectrum, coding uye modulation, antenna anti-jamming, pa-board processing, shanduko-domain processing, uye amplitude-domain processing, pamwe neadaptive link matekiniki, kuongorora misimboti yavo nemashandisirwo.
1. Kuparadzira Spectrum Technology,
Kupararira spectrum kunowedzera anti-jamming kugona nekuwedzera chiratidzo bandwidth, kuderedza simba spectral density. Yakananga Sequence Kupararira Spectrum (DSSS) inoshandisa pseudo-random macode kuwedzera chiratidzo bandwidth, kuparadzira narrowband kupindira simba. Izvi zvakakosha mukutaurirana kwemauto setiraiti, kupokana nemaune jamming (semuenzaniso, co-frequency kana Broadband ruzha kupindira) kuve nechokwadi chekuraira kwakachengeteka uye kutapurirana kwehungwaru.
2. Coding uye Modulation Technology,
Yepamusoro-soro-yekugadzirisa makodhi (semuenzaniso, Turbo macode, LDPC) akasanganiswa nepamusoro-odha modulation (eg, PSK, QAM) inovandudza spectral kunyatsoshanda uku ichideredza kukanganisa-induced zvikanganiso. Semuyenzaniso, LDPC ine yakakwira-odha QAM inosimudzira kutengeserana setiraiti masevhisi (semuenzaniso, HDTV, internet) uye inova nechokwadi chekutaura kwakasimba kwemauto munzvimbo dzinokwikwidza.
3. Antenna Anti-Jamming Technology,
Adaptive uye smart antennas zvine simba kugadzirisa mapatani ekubvisa majammer. Adaptive antennas inotungamira nulls kune yekukanganisa masosi, nepo smart antennas anoshandisa-akawanda-array kugadzirisa kune spatial kusefa. Izvi zvakakosha muSATCOM yemauto kurwisa kutyisidzira kwehondo yemagetsi.
4. Pa-Board Processing (OBP) Technology,
OBP inoita dhizaini yekudhirowa, kudhirodha, uye nzira yakananga pamasetiraiti, ichidzikisa kusagadzikana kwepasi relay. Zvishandiso zvechiuto zvinosanganisira kuchengetedzwa kwakachengeteka kwenzvimbo kudzivirira kuterera uye kugovaniswa kwezviwanikwa zvekushandisa.
5. Shandura-Domain Processing,
Tekinoroji senge FFT uye wavelet inoshandura inoshandura masaini kuita frequency kana nguva-frequency domains yekukanganisa kusefa. Izvi zvinorwisa Broadband uye nguva-inosiyana-siyana jamming, inovandudza kuchinjika munzvimbo dzakaoma dzemagetsi.
6. Amplitude-Domain Processing,
Limiters uye otomatiki Gain Control (AGC) inodzvanya kupindira kwakasimba (semuenzaniso, mheni kana kurovera kwemuvengi), kuchengetedza maseketi ekugamuchira uye kuchengetedza kugadzikana kwekubatanidza.
7. Adaptive Link Technology,
Real-time gadziriso kune kukodha, modulation, uye data mitengo yakavakirwa pane chiteshi mamiriro (semuenzaniso, SNR, BER) inovimbisa kutaurirana kwakavimbika kunyangwe mamiriro ekunze kana jamming. Mauto masisitimu anowedzera izvi mukusimba mumamiriro ehondo ane simba.
Mhedziso,
Kune dzimwe nyika anti-jamming matekinoroji anoshandisa akawanda-layered nzira dzinotora masaini kugadzirisa, kukodha, uye adaptive masisitimu. Kushandiswa kwechiuto kunoisa pamberi kusimba uye kuchengetedzeka, nepo zvekutengesa zvikumbiro zvinotarisa pakubudirira. Kufambira mberi kweramangwana kunogona kubatanidza AI uye chaiyo-nguva kugadzirisa kupikisa kutyisidzira kuri kubuda.
Chengdu Concept Microwave Technology CO., Ltd inyanzvi inogadzira zvikamu zve5G/6G RF zvekukurukurirana nesatellite kuChina, kusanganisira iyo RF lowpass sefa, highpass sefa, bandpass sefa, notch sefa/bhendi stop filter, duplexer,Simba divider uye directional coupler. Ese anogona kugadzirwa zvinoenderana nezvinodiwa zvako.
