It was reported [J. Acoust. Soc. Am. 93, 1460--1465 (1993)] that the Doppler component and both the magnitude and phase of an object's transfer function could be extracted from the fourth-order cumulant spectrum. Results for three elastic spherical objects in motion will be discussed. Specifically, performance results for the extraction of the Doppler component, phase, and magnitude of the object's transfer function from the fourth-order cumulant spectrum will be compared with classical first- and second-order methods.
