The impulse response method is often used tostudy the ultrasonic field radiated by planar orgently curved transducers. These investigationscan be extended to include the reflected echoesfrom point reflectors, which can be used in syntesizingechoes from reflectors of known shapes.The single point echo can be measured directlybut there are however certain problems associatedwith this. This paper proposes an alternativemethod to estimate the echo from a point-like reflectorby measuring...
