Abstract

A motion-estimation technique for coherent underwater acoustic imaging systems is presented. This technique does not require point feature selection or matching correspondence identifcation. The rotation matrix is estimated from the covariance matrices of the amplitude distributions of the wavefield spectra, and the translation vector can be obtained subsequently from the phase change in the spatial-frequency domain.
