I-electromagnetic spectrum ibe sisixhobo esinqabileyo. Ukukhusela iinkqubo zeRF zebroadband kwindawo ezixineneyo zombane okanye amaza omoya anobutshaba, iDARPA isungula inkqubo. . Ukukhethwa kwabagqatswa kuya kuqala ngoFebruwari.
Ukukhutshwa kweendaba kuye kwapapashwa kwiwebhusayithi ye-Arhente yeeProjekthi zoPhando oluPhezulu lwase-US (i-DARPA) ebhengeza ukuqaliswa kwenkqubo ye-WARP (i-Wideband Adaptive RF Protection). I-DARPA iyazithanda izifinyezo ezizichazayo. Igama lenkqubo entsha linokuguqulelwa njenge "wormhole" - indawo emangalisayo yendawo apho umgama ongenakucingelwa unokoyiswa ngaphandle kokuphazamiseka. Inkqubo yeWARP ayizenzi ngathi yintsomi yesayensi, kodwa ithembisa ukunceda amajoni kunye nabemi bayeke ukugilana ngeengqiniba kumaza omoya kanomathotholo.
Ukusebenza kweesistim zerediyo zerediyo ngohlobo lweerada okanye uthungelwano lonxibelelwano luya lufumana uphazamiseko oluvela kuzo zombini iisignali zayo kunye nezangaphandle. Xa sijamelene nenkcaso yotshaba, iingxaki ziya kwanda amaxesha amaninzi, nto leyo ebeka isoyikiso ekufezekisweni kwemishini. Iindlela zangoku zokunciphisa uphazamiseko lwe-wideband receiver zincinci kwaye zikhokelela kurhwebo-offs kubuntununtunu bomqondiso, ukusetyenziswa kwe-bandwidth, kunye nokusebenza kwenkqubo. Kodwa uninzi lwale parameters alunakuncama.
Ukusombulula iingxaki zokukhusela izikhululo zerediyo zedijithali ukusuka kowona mngcipheko mkhulu wokuphazamiseka, kucetywa ukuba kuphuhliswe itekhnoloji "yerediyo yokuqonda". Iinkqubo ze-RF kuya kufuneka ngokuzimeleyo "ziqonde" imeko ye-electromagnetic emoyeni kanomathotholo kwaye, umzekelo, ngohlobo lwezihluzo ezihanjiswayo ezibanzi, zilungelelanise ngokuzenzekelayo ukugcina uluhlu oluguquguqukayo lomamkeli ngaphandle kokunciphisa ubuntununtunu okanye umqondiso webandwidth.
Ukulwa nokuveliswa kokuphazamiseka ngumthombo wakho, inkqubo ye-WARP incoma ukudala i-adaptive signal suppressors ye-analog. Ngamanye amaxesha i-transmitter yenkqubo ngowona mthombo mkhulu wokuphazamiseka kumamkeli. Ukwenza oku, ulwamkelo kunye nokudluliselwa ngokuqhelekileyo kuqhutyelwa kwiifrikhwensi ezahlukeneyo. Kwiimeko zokunqongophala kwe-spectrum, kunengqiqo ukusasaza kumacala omabini kwi-frequency efanayo, kodwa kubalulekile ukungabandakanyi impembelelo ye-transmitter kumamkeli. Ukuza kuthi ga ngoku, le ngcamango isetyenziswe kumda olinganiselweyo, apho i-WARP iya kufuneka ijongane nokusebenzisa abaxhasi be-analog kunye nokusetyenzwa kwedijithali okulandelayo.
Okokugqibela, uphuhliso oluphantsi kwenkqubo ye-WARP luya kunceda ukwandisa usetyenziso lwengqikelelo entsha yerediyo echazwe kwisoftware (SDR) kwindawo exineneyo kunye neguqukayo ye-spectrum, elinganiselwe ngoku. Umkhosi wase-US usebenzisa iteknoloji ye-SDR ukuhambisa kunye nokusebenza kwemiqondiso usebenzisa i-frequencies kunye nemigangatho eyahlukeneyo. Umkhosi wase-US uthembele kwii-SDRs ukuseka unxibelelwano phakathi kweeyunithi kunye nemikhosi ehlangeneyo. Kodwa kwiimeko ezilinganiselweyo, itekhnoloji ye-SDR ayisebenzi kakuhle.
