I-spectrum ye-electromagnetic isiphenduke insiza eyivelakancane. Ukuze kuvikelwe izinhlelo ze-broadband RF ezindaweni eziminyene kagesi noma amaza omoya anobutha, i-DARPA yethula uhlelo. . Ukukhethwa kwabazongenela ukhetho kuzoqala ngoFebhuwari.
Ukukhishwa kwabezindaba kushicilelwe kusizindalwazi se-US Defence Advanced Research Projects Agency (DARPA) ememezela ukwethulwa kohlelo lwe-WARP (Wideband Adaptive RF Protection). I-DARPA iyawathanda ama-akhronimi azichazayo. Igama lohlelo olusha lingahunyushwa ngokuthi "i-wormhole" - indawo enhle yesikhala lapho amabanga angenakucatshangwa anganqotshwa ngaphandle kokuphazamiseka. Uhlelo lwe-WARP aluzenzi njengenganekwane yesayensi, kodwa luthembisa ukusiza amasosha kanye nezakhamuzi ukuthi ziyeke ukugigiyela ngezindololwane kumaza omsakazo agcwele kakhulu.
Ukusebenza kwamasistimu efrikhwensi yomsakazo ngendlela yama-radar noma amanethiwekhi okuxhumana kuya ngokuya kuba nokuphazamiseka okuvela kumasignali awo nawangaphandle. Lapho kubhekene nokuphikiswa kwesitha, izinkinga zizokhula ngokuphindaphindiwe, okubeka usongo ekufezweni kwemishini. Izindlela zamanje zokunciphisa ukuphazamiseka kwesamukeli se-wideband zincane futhi ziholela ekuhwebeni kokuzwela kwesignali, ukusetshenziswa komkhawulokudonsa, nokusebenza kwesistimu. Kodwa eziningi zale mingcele azikwazi ukunikelwa.
Ukuze kuxazululwe izinkinga zokuvikela iziteshi zomsakazo zedijithali ze-broadband kusukela ku-spectrum enkulu yokuphazamiseka, kuhlongozwa ukuthi kuthuthukiswe ubuchwepheshe "bomsakazo wokuqonda". Amasistimu e-RF kuyodingeka βaqondeβ ngokuzimela indawo ye-electromagnetic emoyeni womsakazo futhi, isibonelo, ngendlela yezihlungi eziguqulekayo ze-wideband, azivumelanise ngokuzenzakalela ukuze kugcinwe ububanzi obuguquguqukayo bomamukeli ngaphandle kokunciphisa ukuzwela noma umkhawulokudonsa wesiginali.
Ukuze ulwe nokukhiqizwa kokuphazanyiswa ngumthombo wakho siqu, uhlelo lwe-WARP luncoma ukuthi udale izicindezeli zesignali ye-analog eziguquguqukayo. Kwesinye isikhathi isidlulisi sesistimu uqobo siwumthombo omkhulu wokuphazamiseka kumamukeli. Ukwenza lokhu, ukwamukela nokudluliswa kuvame ukwenziwa ngamafrikhwensi ahlukene. Ezimweni zokushoda kwe-spectrum, kunengqondo ukusakaza kuzo zombili izinkomba ngefrikhwensi efanayo, kodwa kubalulekile ukungafaki ithonya lesidlulisi kumamukeli. Kuze kube manje, lo mqondo ususetshenziswe ngezinga elilinganiselwe, i-WARP ezobhekana nalo ngokusebenzisa izinxephezelo ze-analog kanye nokucutshungulwa kwedijithali okulandelayo.
Okokugcina, intuthuko ngaphansi kohlelo lwe-WARP izosiza ekukhuliseni ukusetshenziswa komqondo omusha we-software-defined radio (SDR) ezindaweni eziminyene neziguquguqukayo ze-spectrum, okwamanje ezilinganiselwe. Ibutho lase-US lisebenzisa ubuchwepheshe be-SDR ukuze lidlulise futhi licubungule amasignali lisebenzisa amaza namazinga ahlukene. Ibutho lase-U.S. lithembele kuma-SDR ukuze asungule ukuxhumana phakathi kwamayunithi namabutho ahlangene. Kodwa ezimeni ze-spectrum elinganiselwe, ubuchwepheshe be-SDR abusebenzi kahle.
