Abstract

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.

弹道目标的探测和跟踪
本文分析了弹道目标探测与跟踪的几个方面。特别地,从一个概念目标的CAD模型出发,得到了该目标随俯角的RCS模型。随后,推导了弹道目标的运动学模型;它包括作用在它上面的主要力,即推力、阻力和重力。在这两个模型的基础上,可以确定假设l波段雷达在目标飞行过程中的探测概率,并建立目标跟踪的交互式多重模型。通过蒙特卡罗仿真对设计的IMM跟踪算法进行了性能评价。特别地,高机动飞机和弹道目标在助推阶段被用来检查IMM的能力。
