一种空中发射弹道导弹摄动制导方法

An Air-launched Ballistic Missile Disturbance Guidance Method Research

为解决弹道导弹空中发射时发射点位置不能预先确定对摄动制导的影响,分析了在空中发射方式下实现摄动制导的制约因素;通过弹道差分的方法求取了诸元偏导数,给出确定了发射点位置偏差后,快速修订诸元的方法;实现了弹道导弹空中发射时的摄动制导。仿真验证表明该方法具有速度快,占用空间小的特点,可满足制导精度及弹载计算机计算能力的要求。

To solve the air-launched ballistic missile launch point which can not pre-determine the impact of disturbance guided,the facts of constraints to achieve the air-launched disturbance guided is analyzed,through the various differential trajectory to strike data partial derivatives.The way is given that when determining launching point deviation,fast to amend the data,achieved the air-launched disturbance guided of ballistic missiles.Simulation results show that the method has the merit of speeding and using small space and can meet the guided precision and missile computer computing power requirements.
