Abstract:	Shipboard radar is used to estimate the relative position and velocity of nearby ships for potential use in collision-avoidance. The noise in the radar data, and the small perturbations in the ship motion both have an influence on the steady-state error or uncertainty in these estimates. Optimal filtering is modelled with a range of these parameters, and the variation of position uncertainty is found with respect to both of these noise sources, and with respect to the sample interval.
