  • Guidance system
    Patent number: 6651004
    Abstract: A method and apparatus for directing a pursuing vehicle, such as a torpedo, on an intercept trajectory from a launching vehicle to a target vehicle with evasion capabilities. The guidance system bases a solution on vectors on a first Cartesian coordinate system. Evasive maneuvers for the target vehicle are based upon vectors on a second Cartesian coordinate system. The guidance system converts the evasive maneuver to the first coordinate system and then performs an iterative process using initial guidance parameter values to determine, upon convergence of the solutions, final guidance parameters for the target vehicle.
