Open the CIPO recordAbstract From the Canadian patent
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 VT 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.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 VT, when such tracking data is available and otherwise; d) estimating actual target maneuver to develop a minimum uncertainty zone using an …
