Abstract

Eine Schalllaufzeitmessvorrichtung enthält einen Schallsende- und Empfangsabschnitt, der ein Schallelement aufweist zum Senden und Empfangen von Schallwellen, einen A/D-Wandler, der ein Echosignal, das von einem Zielobjekt reflektiert wird, welches zu messen ist, in ein digitales Signal umwandelt, einen Inverse-Analysis Abschnitt, der das digitale Echosignal in ein Impulssignal durch eine inverse Analysis konvertiert, wobei das digitale Echosignal mit einer inversen Matrix multipliziert wird, einen Berechnungsabschnitt, der eine Schalllaufzeit und eine Laufzeitdifferenz, basierend auf dem digitalen Echosignal, das in das Impulssignal konvertiert wurde, misst und einen Anzeigeabschnitt, der die Schalllaufzeit und Laufzeitdifferenz, die durch den Berechnungsabschnitt berechnet worden sind, anzeigt.
