Abstract
Estimation of positions, amplitudes, and the relative phase of double star targets is considered for an imaging system when the image pattern is registered by an incoherent array of photodetectors. An analytical framework is developed to establish the fundamental limits on the resolution of an imaging system and to obtain a quantitative understanding of the dependence of the accuracy of estimation upon the separation between targets and on the number of photons available. The additional number of signal photons required to obtain a desired accuracy for any parameter when the number of unknown parameters increases is computed and discussed for selected cases. Targets representing sources which can be either mutually coherent or incoherent are considered.
