Abstract
The article presents a generalized structure of a correlation system, which includes a two-dimensional correlator memory, a preprocessor, a reference memory, and a control unit. Two variants of hardware realization of two-dimensional correlator memory as part of an optoelectronic correlation system are proposed. The functional capabilities of an alternative method of correlation processing of the current optical image are considered, which allows to determine the location of the reference center on the field of the current image. The regular structure of the two-dimensional memory of the correlator ensures its compact placement on a promising element base - on an FPGA chip or on a matrix of smart pixels.
