In this paper the kinematics of a proportional navigation homing guidance trajectory have been simulated, first without any initial heading errors or target maneuvers and then with certain inserted angular errors to simulate a jamming effect that be maximized. We demonstrate in the same paper that the inserted angular error has to be time varying; such that additional false guidance commands are continuously generated which deviate the missile from its correct trajectory. Different methods can be adopted to induce such angular errors which are out of the scope of this paper. The simulation results have been congruent with the theoretical discussion: Zero miss-distance has resulted without jamming. With constant inserted angle error the guidance system has succeeded to recover with a negligible miss-distance. Different laws of variation have been proposed for the inserted angular error and their parameters have been optimized for maximum possible miss-distance. Miss-distances in excess of 4 kilometers have been achieved.
