Statistical estimation of ultrasonic propagation parameters for aberration correction |
摘要 |
In estimation of an aberration in propagation of an ultrasonic wave from an aperture through an aberration path, the aperture is modeled as a plurality of sources and receivers. The frequency-domain magnitude of the aberration is estimated by normalizing the scattered signal power spectrum. The frequency-domain phase of the aberration is estimated by a recursion using cross spectra of signals at neighboring receivers.
