Abstract

En fremgangsmåte for måling av lydens hastighet gjennom et fluid som rommes i et langstrakt legeme, hvor lyden i alt vesentlig beveger seg gjennom det langstrakte legeme langs en retning som ligger på linje med det langstrakte legemes lengste akse, idet lyden forårsaker en momentan forandring i trykket i en del av fluidet idet lyden beveger seg gjennom denne del av fluidet, hvilken fremgangsmåte innbefatter følgende trinn: anordning av en gruppe av minst to følere fordelt på forutbestemte steder langs det langstrakte legeme, hvor hver føler skal skjelne og signalisere rom-tidsavsøkte. data som innbefatter informasjon om fluidets trykk ved. føleren; innsamling av rom-tidsavsøkte data fra hver føler. på hvert av en rekke suksessive øyeblikk i tid;. konstruksjon av en graf som kan utledes fra en graf, ved. bruk av en teknikk som velges fra gruppen som består av. spektralbaserte algoritmer, som for eksempel Capon-metoden eller MUSIC-metoden, hvor det dannes en. spektrallignende funksjon av lydens hastighet, og. parametriske løsningsmetoder, som for eksempel den. deterministiske maksimale sannsynlighetsmetode;. identifisering av en spektralrygg i grafen og bestemmelse. av spektralryggens retningskoeffisient; og bestemmelse av. lydens hastighet gjennom å anta en sammenheng mellom. lydens hastighet og spektralryggens retningskoeffisient.
