Accurate tracking of targets flying at low altitude above a smooth surface is difficult because of the surface reflection. We propose a solution to this problem based on deterministic physical modelling of the specular multipath used with the maximum likelihood method. We incorporate the effects of target fluctuation statistics in our model to develop a family of estimators for different target fluctuation models. We derive the Cramer-Rao bounds corresponding to the various target fluctuation models and the refined propagation model. Monte-Carlo simulations compare performance with the Cramer-Rao bound and demonstrate the threshold effects for both fluctuating and non-fluctuating Swerling target models.
