Abstract
Innsamlede signaler som representerer sampler av propagerende bølgefelter er prosessert ved bruk av metoder med koplede variable i rom og tid for å danne bilder med bedre skarphet og oppløsning enn de som kan oppnås ved • konvensjonelle metoder. Frekvenser man har fått adgang til inkluderer både de som er mulige og de som tilsynelatende er utover de som er ansett for å være mulige i henhold til både Nyquist-kriterier og i forhold til de som er til stede i bølgefeltkilden.Signalene og de fysiske trekkene kan oppnås i f.eks. tomografi (medisinsk CT-scanning), ekkolokalisering (radar eller sonar) eller seismisk avbildning. Signaler prosesseres ved å opprettholde det innbyrdes forholdet av de koplede variablene for tid og rom, heller enn å følge de konvensjonelt aksepterte nåværende teknikkene som behandler tiden og romvariablene uavhengig.Skarphet og oppløsning av bilder er oppnådd ut over de som normalt er ansett for å være mulige med tidligere teknikker, ved forståelse av og korrekt tolking av informasjonsinnholdet i et samplet bølgefelt. Datainnsamlingshastighet kan økes sterkt, mens innsamlingskostnader også blir redusert siden de beskrevne metodene krever mindre data og bruker slike data som er tilgjengelige, mer effektivt.
