动能拦截弹末段制导导引律设计与仿真实现

大气层外动能拦截弹(EKV)是导弹攻防系统中一个重要的拦截作战系统。为了提高制导精度,在末段制导过程中必须采用性能优良的导引律。针对反导导弹末段的飞行特点及应用场合,根据脱靶量最小的原则,设计并实现了三维扩展比例导引模型。扩展比例导引在经典比例导引模型的基础上,通过对目标角加速度的估计,判断目标的运动趋势,可有效提高拦截精度。仿真图形及脱靶量实验对比结果证实了该导引方法的有效性及实用性。

Guidance Law Design and Simulation Implementation in the Terminal Control of Exoatmospheric Kill Vehicle

Exoatmospheric Kill Vehicle (EKV) is an important interceptor combat system in the whole missile defense system. In order to improve the guidance accuracy, an efficient guidance law should be adopted in the terminal control. According to the flight characteristics and application occasions of anti-ballistic missiles in the terminal control, designs and implements the three-dimensional extension proportional guidance based on principle of minimum miss distance. This guidance law adds the acceleration estimation of targets based on the classical proportional guidance in order to estimate the motion trends of targets, which can improve the interception accuracy effectively. The simulation figures and miss-distance experiment results verified the effectiveness and utility of this guidance method.
