Umugqa Wokulibaziseka Olawulwa Ngedijithali, 0.1~18GHz, Ububanzi Bokulibaziseka 1.25~78.75ps, Isinyathelo 1.25ps

Imigqa Yokulibaziseka Elawulwa Ngedijithali ingamadivayisi kagesi akwazi ukuhlinzeka ngokulawula ukubambezeleka kwesikhathi okunembile nokuhlelekayo kwezimpawu ze-RF/microwave. Ngokuhlanganisa amaseli amaningi okulibaziseka kanye nezishintshi ze-RF ezisheshayo, ashintsha isignali yokufaka phakathi kwezindlela zokudlulisela ezinobude obuhlukene ngaphansi kwezibonakaliso zokulawula zedijithali, ngaleyo ndlela athole ukubambezeleka okusethwe kusengaphambili ekuphumeni. Uma kuqhathaniswa nama-phase shifters endabuko, imigqa yokulibaziseka elawulwa ngedijithali inikeza "ukubambezeleka kwesikhathi sangempela", okugwema ngempumelelo umphumela wokugoba kwe-beam okwenzeka kumasignali e-wideband ngesikhathi sokuskena kwe-beam. Ziyizingxenye ezibalulekile zokusebenzisa ama-array ahlukaniswe nge-wideband, ama-radar anesinqumo esiphezulu, kanye nezinhlelo zokulinganisa ezinembile kakhulu. Okulandelayo yisingeniso sezici kanye nokusetshenziswa kwemigqa yokulibaziseka elawulwa ngedijithali engu-0.1 ~ 18GHz.

Izici:

1. Imvamisa yokusebenza ye-Ultra-wideband
Imvamisa yokusebenza ihlanganisa i-0.1 ~ 18GHz, kusukela ku-L-band kuya ku-Ku-band, ihlangabezana nezidingo zokucubungula isignali zezinhlelo eziningi ze-RF/microwave. Ngokuklama okuhambisanayo kokunciphisa amaseli okulibaziseka kwangaphakathi, umthelela wokushintsha kwemvamisa ekusebenzeni kokulibaziseka ucindezelwa ngempumelelo, kugcinwa izici zokulibaziseka ezizinzile phezu kwe-band ephelele.
2. Ukulibaziseka okuhleliwe okunembe kakhulu
Ukulawula kwedijithali kuvumela ukulungiswa kokulibaziseka okunembile, ngesinyathelo sokulibaziseka esiphansi njenge-1.25ps kanye nenani lokulibaziseka eliphelele elifika ku-78.75ps. Ukunemba kokulibaziseka okuvamile kufinyelela ku-±4ps, okwanelisa izinhlelo zokusebenza ezidinga ukulungiswa kwesikhathi esiphezulu kakhulu.
3. Ukulahlekelwa okuphansi kokufakwa kanye ne-VSWR enhle
Igcina ukulahlekelwa okuphansi kokufakwa phezu kwebhendi ephelele, okuzuzisa isabelomali sesixhumanisi sesistimu kanye nobuqotho besiginali.
4. Ukwenziwa kube lula kanye nokuhlanganiswa okuphezulu
Ubuchwepheshe obuthuthukisiwe bomugqa wokudlulisa we-microwave kanye nezinqubo zokukhiqiza ze-semiconductor zihlanganisa izintambo zokulibaziseka zekhebula noma ze-coaxial ezivamile zibe yiphakheji encane, zinikeza ukubambezeleka okuzinzile, ikhono eliqinile lokulwa nokuphazamiseka, kanye nokuhlanganiswa okulula kwesistimu, kunqobe ukushiyeka kwezintambo zokulibaziseka zendabuko njengosayizi omkhulu, ukulahlekelwa okuphezulu, kanye nokusabalala okukhulu.

Izicelo:

1. I-radar ye-wideband ehlukaniswe ngezigaba
Kuzinhlelo ze-radar ze-wideband phased array, ukukhomba kwe-antenna beam kuyashintshashintsha ngemvamisa yokusebenza ngenxa yemiphumela yokuvula. Imigqa yokulibaziseka elawulwa ngedijithali inikeza isinxephezelo sokulibaziseka kwesikhathi sangempela, iqeda ngempumelelo ukugoba kwe-beam futhi ithuthukise ukunemba kokuma kwe-radar kanye nesisombululo se-angular. Ziyizingxenye eziyinhloko kuma-subarrays angaphambili e-RF ama-radar e-phased array.
2. Izinhlelo zokuxhumana kanye nokucubungula amasignali
Ezokuxhumana zedijithali, ukuxhumana kwesathelayithi, kanye nezinhlelo zempi ze-elekthronikhi, imigqa yokulibaziseka elawulwa ngedijithali ikhokhela umehluko wokulibaziseka kokusabalala phakathi kweziteshi ezahlukene zesignali, ukufeza ukuqondanisa kwesikhathi, ukuvumelanisa iwashi, kanye nokulungiswa kwesigaba, ukuthuthukisa ukusebenza kwesilinganiso samaphutha e-bit yesistimu kanye nekhwalithi yesignali.
3. Ukulinganiswa nokuhlolwa kwe-radar
Ekuhlolweni kwelabhorethri kanye nokulinganiswa kwesistimu ye-radar, imigqa yokulibaziseka elawulwa ngedijithali isebenza njengemithombo yokubhekisela yesikhathi enembile kakhulu, ilingisa izimpawu ze-echo ezivela ezinhlosweni ezikude ezahlukene, isekela ukuqinisekiswa kokusebenza kwe-radar, ukuhlolwa kwephethini ye-antenna, kanye nemisebenzi yokuzihlola yesistimu.
4. Izinhlelo zempi ze-elekthronikhi kanye nokuhlola
Ezinhlelweni zokuhlola nokufaka i-elektroniki, imigqa yokulibaziseka elawulwa ngedijithali ingadala umehluko wesikhathi ukuze ivumele ukugcinwa nokudluliselwa kwesignali, ukukhiqizwa kwe-jamming okuvumelanayo, kanye nokulinganiswa komehluko wesikhathi sokufika (i-TDOA), okwenza kube yizingxenye zokulawula ukubambezeleka kwesikhathi okunembile okubalulekile emishinini yempi kagesi.
5. Amamojula e-T/R
Kumamojula e-T/R ama-antenna e-phased array, imigqa yokulibaziseka elawulwa ngedijithali isebenza ngamakhodi esistimu yokuqondisa i-beam ukuze kufezwe ukulawulwa kwesikhathi okunembile kwezimpawu zento ngayinye ye-array, ngaleyo ndlela kufezwe ukwakheka kwe-beam kanye nokuskena kwe-beam okusheshayo. Izinhlelo ezinjalo zidinga imigqa yokulibaziseka ene-bandwidth ebanzi, ukulahlekelwa okuphansi kokufakwa, ukuhambisana okuhle kwesigaba, kanye nekhono lokushintsha isiteshi ngesivinini esikhulu.

I-Qualwave Inc. inikeza ububanzi obukhulu, ububanzi obuguquguqukayoimigqa yokulibaziseka elawulwa ngedijithalingamaza afinyelela ku-18GHz. Lesi sihloko sethula umugqa wokulibaziseka olawulwa ngedijithali onebanga lemvamisa elingu-0.1~18GHz, ibanga lokulibaziseka elingu-1.25~78.75ps, isinyathelo esingu-1.25ps.
