ABSTRACT:
A method for determining the position and velocity of a target in inertial space including the steps of (a) tracking the target and providing three orthogonal velocity components in inertial space; (b) computing the scalar velocity V.sub.T of the target in an inertial reference frame by providing the square root of the sum of the squares of the orthogonal velocity components; and (c) computing the aspect angle .beta..sub.cue of the target relative to a line-of-sight to a platform as an inverse sinusoidal function of the ratio of one of said orthogonal components and V.sub.T, when such tracking data is available, and otherwise; (d) estimating actual target maneuver to develop a minimum uncertainty zone using an assumed worst case lateral target acceleration. Also disclosed are techniques for bounding the aspect angle and for providing global range and range rate estimates which account for uncertainties in the measurements of target and platform ranges and velocities.
