Photocounting Image Tracking of Fluctuating Targets.

摘要

A theory of estimation of angular position and other attributes of optically rough and smooth targets with a monopulse laser radar is developed. It applies to systems deriving information about the target position by sensing its image with an array of noncoherent detectors. The theory develops quantitative formulations of the fundamental limitations imposed upon measurement accuracy by the shot noise arising from both the target return and the background radiation, by the detector dark current, and by the random fluctuations of the target cross section.
