| ABSTRACT In this paper we introduce a complete modelling and simulation of both target and missile trajectories in one plane with and without the effect of phase front distortion jamming. Although the missile guidance is done in two independent perpendicular planes, the simulation process in the other plane will be identical to that included in this model. Besides, the time variation of different variables in the missile radar guidance system are computed and displayed, to monitor the system performance along the missile trajectory starting from the missile launch up to the impact point. The impact is defined here as the time instant when the rate of variation of the relative speed measured by the missile radio fuse crosses the zero value. This is the same definition adopted by the radio fuse system. The missile-target range at this instant is calculated and displayed as the final miss-distance. Without such a simulation, it is not possible to evaluate an angular deception technique and optimize its parameters; since the instantaneous effect of angle deception will be recovered by the proportional navigation guidance system and the only criterion of jamming effectiveness is the final miss-distance [1]. The simulation program is written as an m-file to be run in MATLAB environment. | ||||
