Iyo electromagnetic spectrum yave chinhu chinoshomeka. Kuchengetedza Broadband RF masisitimu munzvimbo dzakazara magetsi emagetsi kana mafungu emhepo ane hutsinye, DARPA iri kutangisa chirongwa. . Kusarudzwa kwevanoda kukwikwidza kuchatanga muna Kukadzi.
Kuburitswa kwenhau kwaburitswa pawebhusaiti yeUS Defence Advanced Research Projects Agency (DARPA) ichizivisa kutangwa kwechirongwa cheWARP (Wideband Adaptive RF Protection). DARPA inoda kuzvitsanangura acronyms. Iro zita rechirongwa chitsva rinogona kududzirwa se "wormhole" - inzvimbo inonakidza yenzvimbo umo madaro asingafungidzirwe anogona kukundwa pasina kukanganiswa. Chirongwa cheWARP hachiedze kunge ngano dzesainzi, asi chinovimbisa kubatsira mauto nevanhuwo zvavo kuti vamire kunetsana nemagokora mumasaisai eredhiyo akazara.
Kushanda kweredhiyo frequency masisitimu nenzira yema radar kana network network kuri kuwedzera kusangana nekukanganisika kubva kune ayo uye ekunze masaini. Mukutarisana nekupikiswa nevavengi, matambudziko achawedzera kakawanda, izvo zvinopa tyisidziro pakuitwa kwemishoni. Nzira dzazvino dzekudzikisa kupindira kwebroadband inogamuchira hazvina kukwana uye zvinokonzeresa kutengeserana mukunzwa kwechiratidzo, kushandiswa kwebandwidth, uye kuita kwehurongwa. Asi mazhinji emaparamita aya haagone kubayirwa.
Kugadzirisa matambudziko ekuchengetedza Broadband dhijitari redhiyo kubva kune yakanyanya kunaka spectrum yekukanganisa, zvinokurudzirwa kuvandudza tekinoroji ye "cognitive radio". RF masisitimu anozofanira kuzvimiririra "kunzwisisa" nharaunda yemagetsi mumhepo yeredhiyo uye, semuenzaniso, muchimiro che wideband tunable mafirita, otomatiki anochinjika kuchengetedza dhizaini yeanogamuchira pasina kudzikisa kunzwa kana chiratidzo bandwidth.
Kurwisa chizvarwa chekuvhiringidzwa nekwako pachako sosi, chirongwa cheWARP chinokurudzira kugadzira anogadzirisa analog sign suppressors. Dzimwe nguva iyo sisitimu inotapurirana ndiyo honzeri huru yekukanganisa kune anogamuchira. Kuti uite izvi, kugamuchira uye kutapurirana kunowanzoitwa pamafafitera akasiyana. Mumamiriro ezvinhu ekushomeka kwespectrum, zvine musoro kutepfenyura mumativi ese parimwe frequency, asi zvakakosha kusabatanidza pesvedzero yeanotumira pane anogamuchira. Parizvino, pfungwa iyi yakashandiswa kusvika padiki, iyo WARP ichafanirwa kubata nekushandisa analog compensator uye inotevera dhijitari kugadzirisa.
Chekupedzisira, kusimukira pasi pechirongwa cheWARP kuchabatsira kuwedzera kushandiswa kweiyo software-defined radio (SDR) pfungwa munzvimbo dzakatsvikinyidzana uye dzine simba rekuona, izvo zvave zvishoma. Mauto eUS anoshandisa tekinoroji yeSDR kufambisa uye kugadzirisa masaini vachishandisa ma frequency uye zviyero zvakasiyana. Mauto eUS anovimba nemaSDR kuti atange kutaurirana pakati pemayuniti nemauto akabatana. Asi mumamiriro ekushomeka kwemaitiro, SDR tekinoroji haishande nemazvo.
