Paper Abstract

In this paper we discuss the estimation of separation and polarization characteristics for a two point target from interferogram when laser backscattered radiation is collected with an incoherent array of polarization sensitive detectors. We establish fundamental limits on the resolution of such a system and obtain a quantitative understanding of the dependence of estimation accuracy on target separation, polarization state and number of photons available. The results obtained in semiclassical limit include Poisson photon statistics. The performance of various estimators is evaluated by utilizing the Cramer-Rao bound, for both signal and background shot noise limited conditions. The results presented are applicable to laser radars, discrimination of closely spaced objects, and provide a better understanding of the system when spatial polarization coding of source is used to transmit information.
