Abstract

Et flettet partikkelhastighetssignal blir generert ved å flette et registrert, vertikalt partikkelhastighetssignal som er skalert i et øvre frekvensområde ved bruk av en tidsavhengig ankomstvinkel som er bestemt ved hjelp av hastighetsanalyse, med et simulert partikkelhastighetssignal som er beregnet i et nedre frekvensområde fra et registrert trykksignal, ved å bruke et tidsvarierende filter basert på den tidsavhengige ankomsttiden. Kombinerte trykk- og vertikale partikkelhastighet signaler blir generert ved å kombinere de registrerte trykk- og flettede hastighetssignalene.
