摘要: A method and apparatus for determining the value of a Doppler frequency shift component Δf present in signal f ± employing correlation process which utilizes Mellin transform is scale invariant. The location peak reference coordinate system used provides measure magnitude Δf. sequence steps involved when optical include forming transmittance pattern Δf, has horizontal that natural log time original signal, similarly scaled f, utilizing first patttern input plane correlator holographic matched spatial filter produced from second contains term corresponding to conjugate its plane.
