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.
