Tracking a Moving Vessel from Bearing Measurements.
Abstract
This paper presents a method for tracking a distant moving target as a function of bearings measured from a tracking platform. The method is an improvement of the Hinich-Bloom passive tracking approach. The target is assumed to be moving at a constant speed on a fixed heading, whereas the platform maneuvers. The direction cosines are computed with respect to a rotation of the coordinate system that places 0 degrees at the mean of the estimated target bearing. This is done to maximize the variation of the sines of the bearings. The coordinate system is rotated to estimate the target coordinates. When the noise is Gaussian, the estimate of target range and heading are approximately maximum likelihood for large target ranges.
