The filter dynamics are built in the three dimensional engagement scenario and the states are composed of relative position, velocity, missile acceleration and targetacceleration.
在三维坐标下，创建包含导弹运动方程、目标运动方程、弹目相对运动方程的滤波模型。

The missile guidance law utilizing nonlinear variable structure control is proposed. The acceleration command input is determined considering the targetacceleration as an uncertainty.
针对导弹拦截问题，在非线性系统滑模变结构控制理论的基础上，提计出一种新型滑模变结构导引律；

If the observed acceleration in case-finding is maintained, DOTS programmes will detect more than 60% of cases in 2005, but they will fall short of the 70% target.
