Application of the taguchi quality method to design navigation constants that are robust to target maneuvers

The object of this paper is to present a quality control approach to design the navigation constants for missile guidance law that are robust for target's maneuverability and missile's performance. Target's maneuvers and missile's time constants are considered to be noise factors and Taguchi Quality Method (TQM) is used to conduct matrix experiments and determine the robust navigation constants. From the simulation results for three kinds of guidance laws, we find that robust navigation constants have a greater ability to enhance the interception of targets that are performing uncertain maneuvers with less interception time and smaller miss distances in the hitting phase.
