Cramer-Rao Bounds on the Accuracy of Location and Velocity Estimations Using CCD Optical Sensors
Abstract
A moving point-target generates a non-circular image on a CCD photo- detector focal plane. Using a two-dimensional Gaussian signal model, we have derived the Cramer-Rao lower bounds for target location and velocity estimators. It is shown that, when the signal and the noise are assumed to be Poisson processes, both the location and the velocity bounds are inversely proportional to quadratic functions of SNR. Keywords include: CCD imaging, Cramer-Rao Bounds, Parameter estimation, and Point spread function.
