Abstract：Targets maneuver along serpentine paths to avoid naval or antiaircraft gun fire. A method was developed to track a target's path and identify the target's rectangular coordinates and rotation angles. Least square filter models are then defined assuming first-order and second-order motion to predict the target motion, bomb impact points and shell miss distances in functional forms. Rotations of the flight path do not affect the filtered parameters for the target motion, but do affect the miss distance. Rotations of the bomb impact point change the shell's flight time. If the change in the flight time is ignored, the miss distance and the rotations do not affect the calculations. Finally, targeting of gun emplacements was simulated to verify the conclusions.
