摘　　要：对脉冲式末制导子弹攻击地面固定目标的导引规律进行了研究.在视线坐标系中建立了子弹相对运动方程,根据零效脱靶量的概念,给出了脉冲发动机的点火曲线,并得到发动机正确的推力方向.仿真计算表明,该导引规律能有效的抑制目标视线的旋转,保证子弹对目标实施精确打击.In this paper, the guidance law for impulse terminal guidance sub-munitions is studied. It is used to attack immobile targets on the ground. In the line-of-sight coordinate system, the relation motion equation is given and the ignition line of impulse engines is put forward according to the concept of zero effort miss, and the correct thrust orientation is gotten. The computational results show that this guidance law can restrain turn rate of line-of-sight effectively and insure precision attack to the target.
