Abstract
This work analyses the method of correlational accumulation (averaging) of a set of multiple copies of a signal from the same object arbitrarily displaced with relation to one another and observed in a mixture with additive signal independent sensor noise in which the signal displacements are measured by localization of maximum of the signal cross-correlation function. Three main problems are addressed and investigated both analytically and bycomputer simulation: optimility of the correlational accumulation method, signal distortions which originate from the signal registration errors and noise reduction capability of the correlational accumulation as a function of signal-to-noise ratio in the observed signal-plus-noise realizations.
