一种预测拦截未制导方法

A KIND OF PREDICTIVE INTERCEPT FOR TERMINAL GUIDANCE

本文提出一种预测拦截末制导方法。用等价预测碰撞线代替预测碰撞线,只需要探测视线的角速度,使需要探测的参数减少。文中还提出了外扰动常驻条件下,渐近稳定系统的设计方法。应用该方法设计出的末制导系统,可使导弹的攻击区扩大到一个蛋形球空间,使原理脱靶量趋于零。为说明以上结论,给出了仿真结果。

This paper presents a new terminal guidance law for predictive intercept. If predicted collision courses are replaced with equivalent collis'on courses, this method only needs to measure the rotation rate of the Line-of-Sight, therefore, the measured parameters are reduced. This paper also presents a new approach for designing of the asymptotive guidance systems when external disturbances exist. By suing it to design these guidance systems, they can wide the attack zone of missiles to a egg-shape space and make principle miss distances tend to zero. For demonstrating above conclusions, the simulation results for trajectories of a missile are given.
