Abstract

When optical correlators are used for target location measurement or tracking, errors in the position estimation may be induced by the presence of noise and additional objects in the field of view. The variance of the positioning error is evaluated with its dependence on the capabilities of the spatial filter to discriminate among the patterns in the observation field, the shape of the correlation functions, and the noise.
