Abstract:

A mathematical model for passive optical sensors, which takes into account the inherent shot-noise process, is presented. Based on this sensor model, the Cramer-Rao bounds on the variances of intensity and angular location estimates for two closely spaced optical targets are derived. Representative results for the estimation performance degradation due to the interfering targets are shown.
