Ma electromagnetic spectrum asanduka chida chosowa. Kuteteza machitidwe a Broadband RF m'malo odzaza ndi ma electromagnetic kapena ma airwaves oopsa, DARPA ikuyambitsa pulogalamu . Kusankhidwa kwa ofuna kusankhidwa kudzayamba mu February.
Kutulutsa kwa atolankhani kwasindikizidwa patsamba la US Defense Advanced Research Projects Agency (DARPA) kulengeza kukhazikitsidwa kwa pulogalamu ya WARP (Wideband Adaptive RF Protection). DARPA amakonda mawu ofotokozera okha. Dzina la pulogalamu yatsopanoyo limatha kumasuliridwa kuti "wormhole" - dera losangalatsa la danga lomwe mtunda wosayerekezeka ukhoza kugonjetsedwa popanda kusokonezedwa. Pulogalamu ya WARP sikunamizira ngati nthano za sayansi, koma ikulonjeza kuthandiza asitikali ndi anthu wamba kusiya kumenyana ndi zigongono zawo pamawayilesi odzaza ndi wailesi.
Kachitidwe ka ma frequency a radio mu mawonekedwe a radar kapena maukonde olumikizirana akuchulukirachulukira kusokonezedwa ndi ma siginecha ake komanso akunja. Poyang'anizana ndi chitsutso cha adani, mavuto adzawonjezeka nthawi zambiri, zomwe zimawopseza kukwaniritsidwa kwa utumwi. Njira zamakono zochepetsera kusokoneza kwa mawilofoni olandirira ndizovuta kwambiri ndipo zimabweretsa kusinthanitsa pakukhudzidwa kwa ma siginecha, kugwiritsa ntchito bandwidth, komanso magwiridwe antchito. Koma zambiri mwazigawozi sizingaperekedwe.
Kuti athetse mavuto oteteza mawayilesi apawayilesi amtundu wa digito kuti asasokonezedwe, akuyenera kupanga ukadaulo wa "wailesi yozindikira". Makina a RF adzayenera "kumvetsetsa" mlengalenga wamagetsi pawailesi ndipo, mwachitsanzo, ngati zosefera za wideband tunable, zimasinthiratu kuti zisungike kusinthasintha kwa wolandila popanda kuchepetsa kukhudzika kapena bandwidth yama siginecha.
Pofuna kuthana ndi kusokonezedwa ndi gwero lanu, pulogalamu ya WARP imalimbikitsa kupanga zopondereza za analogi. Nthawi zina makina opangira makinawo ndiye gwero lalikulu losokoneza wolandila. Kuti muchite izi, kulandira ndi kufalitsa kumachitika pafupipafupi mosiyanasiyana. Pakakhala kuchepa kwa ma sipekitiramu, ndizomveka kuulutsa mbali zonse ziwiri pafupipafupi, koma ndikofunikira kusiyanitsa mphamvu ya transmitter pa wolandila. Pakadali pano, lingaliro ili lakhala likugwiritsidwa ntchito pang'ono, zomwe WARP ikuyenera kuthana nazo pogwiritsa ntchito ma compensators a analogi ndikusintha kwa digito.
Pomaliza, zomwe zikuchitika pansi pa pulogalamu ya WARP zithandizira kukulitsa kugwiritsiridwa ntchito kwa lingaliro latsopano la pulogalamu-defined radio (SDR) m'malo odzaza ndi ma spectrum, omwe pano ali ochepa. Asitikali aku US amagwiritsa ntchito ukadaulo wa SDR kutumiza ndikusintha ma siginecha pogwiritsa ntchito ma frequency ndi miyezo yosiyanasiyana. Asitikali aku US amadalira ma SDR kuti akhazikitse kulumikizana pakati pa magulu ankhondo ndi mabungwe ogwirizana. Koma mumikhalidwe yocheperako, ukadaulo wa SDR sugwira ntchito bwino.
