Abstract

In this paper we study different factors affecting the angular tracking error of a modern radar homing missile induced by phase front distortion jamming. The normalized induced angular error due to jamming is defined as an objective function to be maximized. An analytical formula for its computation is adopted and the effect of each factor on that function is studied analytically and numerically. Those factors related to the self-protection jamming system parameters are studied as an approach to optimize the system specification, whereas the other factors, which are out of control, are studied to minimize their negative effects on the jamming performance. It is not enough just to maximize the induced angular error to get a successful deception effect on a homing-guided missile. The induced error has to be time-variant and to exist for the longest possible periods of time. That is why we tried also to maximize the ranges of variation of different parameters that guarantee a certain minimum desired value for the induced error. The results can be considered as a basis for the jamming system specification and design.
