Detection and tracking of ballistic target

Some aspects of detection and tracking of ballistic targets are analysed in this paper. In particular, the RCS model versus aspect angle is obtained for a notional target starting from its CAD model. Subsequently, the kinematic model of the ballistic target is derived; it includes the main forces acting on it, namely, the thrust, the drag and the gravity. On the basis of these two models it is possible to determine the detection probability of a notional L-band radar during the target flight and to build up an interactive multiple model (IMM) for target tracking. The performance evaluation of the design IMM tracking algorithm is obtained via Monte Carlo simulation. In particular, highly manoeuvring aircraft and ballistic targets in the boost phase are used to check the capability of the IMM.
