A new NDT method to detect ultrasonic flaw echoes close to the surface in strongly scattering materials is proposed. The method is based on high-resolution pursuit (HRP), which is a version of matching pursuit (MP) that emphasizes local fit over global fit. Since HRP produces representations which r
