Accuracy of Parameter Estimates for Closely Spaced Optical Targets

Abstract

Cramer-Rao lower bounds on the degradation of measurement precision for closely space optical targets are found. Degradation is more severe than previously thought, especially, for small target separations. The bound obtained by a previous analysis, is, in fact, theoretically identical to the Cramer-Rao bound presented here. The disagreement in results is caused by numerical problems in a computer program used in the previous analysis.
