Reconstruction of the Acoustical Impedance Profile of a Multilayer Medium

The recovery of the acoustical reflectivity function and impedance profile of a layered medium from bandlimited and noisy pulse-echo ultrasonic data is considered. The effects of the transducer and the noise are reduced using Wiener filtering. With further signal processing and a priori knowledge of...
