For KKV without an orbit control engine along its longitudinal axis, an OGL is developed based on the linear kinematical model of space interception, by adopting a new time to go algorithm.
针对纵轴方向没有轨控发动机的KKV,建立空间拦截的线性运动学模型,通过采用新的剩余时间计算方法,提出了拦截任意机动目标的最优导引规律。
The PN-variant guidance algorithms such as OGL and APN require information about target acceleration, but it is difficult to obtain the information without time delay.
PN制导的其它算法则需要目标加速度的有关信息,而这些信息一般难于精确测量。
