Abstract

Although the FRI (Finite Rate of Innovation) model may be feasible in reducing the sampling data andsampling frequency of industrial ultrasound imaging systems,the existing FRI model cannot be well applied due tothe high frequency of reflected signals.In order to solve this problem,a new FRI acquisition method named Sum of Sinc (SoS) filter,which is very suitable for the processing of industrial ultrasound signals,is proposed on the basisof the FRI filter group.Afterwards，the necessary conditions for this method are deduced,and the structure of theSoS filter is presented.From the results of raw one- dimension ultrasound imaging data，the proposed method isfound to be effective and feasible.
